MG MGF Technical - Mystery fuses !
| Help !! Ive just gone to check the fuses on my 99 VVC for both beams as both sides now dont work, and teh fuse box under teh steering wheel shows 2 15amp fuses...but they are know where to be found !! In all there appears 6 fuses listed on the fuse box display lid that cannot be located !?!? Any ideas >? Thanks Steve S931 MJO |
| Steve |
| What are you on about mate? Are you saying that the diagram shows fuse locations that don't exisit or are you saying that 2 of your fuses have mysteriously dissapeared out of the sockets? SF |
| SF |
| Basically, the diagram on the fuse box cover shows 6 fuses on the Right hand side of the Fuse Box (2 of which are the main beam L & R). However, when you look at the fuse box the 6 fuse locations are not there. |
| Steve |
| Problem solved..... The 6 fuses turned up under the bonnet....obvious ! (not) Thanks anyway |
| Steve |
| Thought so, i was just trying to clarify what the problem was. Glad it's sorted. SF |
| Scarlet Fever |
| Shock Horror....it turns out the extra fuses I found under the bonnent ARE NOT ! the ones I was looking for. So, I'm back to square One again.. I have no main beam on my headlights.....and unable to locate the 6 Mystery fuses that are clearly marked on the fuse cover panel... I have now uploaded some pictures of the Fuses, so if anyone is able to shed anylight on this..please let me know... http://www.angelfire.com/my/crapauction/MG/index.html Thanks again steve |

| Steve, we talk about an MGF, do we ? ;) The fuses drawn between the relais and passenger compartment fuse panel have never been anywhere different then under the bonnet. Look at the fuse site @ http://www.mgfcar.de/schedules/fuses About in the middle is the openend bonnet fuse box shown. This at a LHD car. As well the fuse numbers on that site relate to a mgtf, which needs not mean anything, cause they should be the same. Pictures are all from older MGF :) :o) Good luck Dieter |

| ???????????????? Is this a wind up? .... Hang on, expanded the browser to full size... I take it you're NOT referring to fuses 7 to 12 (which are quite clearly there in the fusebox)? Lets have a look in the good old owners handbook to see what they say about them... Ok, the owners manual is not very clear on this. However, the owners manual shows the fuses you're looking for beside the 'main' fuse board in the car, between the fuse box and the relay for the hard-top rear window (or the connector block if you don't have a hard-top). Are the fuses not between the main fuse box and the relays, only further back? Get down there with a torch, as I can't make it out in your picture. Have a look in the big black hole at the right of the spare fuses. I've scoured dieter's site looking for a front-on picture of the fuse box, but with no luck. However, he does have loads of the back of the fuse-box. If you haven't found it by tomorrow, I'll go and have a look myself (not going to do it tonight as I don't have a garage and it's psssng down). Good luck. Leigh |

| *g, no wind up. No April joking ! error in the above link. :( http://www.mgfcar.de/schedules/fuses.htm We are on the same not numbered fuses. BLOWER HRW MAINBEAM MAINBEAM ABS START Oh yes, don't get me wrong. Just follow the instructions. Simple German English, I'm sorry. - Close both doors of the car. - walk behind and open the boot with the key - short grip to the bonnet handle, RH in front of the coolant expansion tank - pull .... Bonnet at the front opens :) - walk around to the front and open the bonnet. - look for a black box in front of the window. On LHD cars it's on the right. Dunno but I think in your RHD car it will for sure be on the left. - Use a screw driver and unlock the black box cover. Voila: http://www.mgfcar.de/fuse/Sicherungskasten.jpg print below the cover: http://www.mgfcar.de/power_boost_valve/dk_DCP_6132.jpg OK ? :o) Take it easy ! Cheer Dieter |

| Fuse box is under the bonnet on passenger side behind battery, small black box with cover over top. Release and lift off cover and fuses are inside. |
| Chris |
| Jep, found a picture anywhere on the HD. http://www.mgfcar.de/fuse/RHD_MGF_4_bonnet_fuse_box.jpg I think I get scalped when he sees that the description under the bonnet fuse box cover is different to the inner fuse box schedule. ;) Included Steves pix to the fuse document, with credits as usual. Hope it is right this way. Nice, the location for the HT relay can clearly be seen. |
| Dieter K. |
| This is not a wind up guys !..trust me. Leigh, Fuses 7-12 do not include L & R Main beam. Also, I can assure you that the 6 Fuses I am talking about are not in the gap between the Fuse box and Relays...I (and my Brother) have both squeezed behind the steering rack with a torch and cannot find them. Dieter/Chris, The 2nd Fuse box under the bonnet still does not include the 2 15Amp Fuses for L & R main beam that I am looking for. I have just taken a picture of it and included it on the bottom of my web site. http://www.angelfire.com/my/crapauction/MG/index.html Perhaps I have what is known as a 'Friday' car and the good chaps at Rover forgot to icnlude the Fuses for L & R main beam. Steve. |
| Steve |
| Of course no wind up. It's an MG ! The hole series got made on Fridays only ... *g*, but they do almost if nothing unusual happens. Beleave only what you see with your own eyes. And what you found is usual at all other of this serie as well. I said already above and it happenend: >I think I get scalped when he sees that the description under the bonnet fuse box cover is different to the inner fuse box schedule. ;) In any you did the better pictures and I now know that RHD and LHD are equal in that location. Batter then nothing, errr.... -------------- Back to the roots: I know of wrong printed stickers and wrong printed owner manuals. Wiring schedules aren't that precise also. Lets try our very best to bring back *Chris beams* Fusepanel diagram: http://www.mgfcar.de/schedules/sb3.jpg Head lamps (see satelite fuse box #21 & #22 & under bonnet fuse 40Amp for LIGHTS) http://www.mgfcar.de/schedules/sb26.jpg Under bonnet fuse box: http://www.mgfcar.de/schedules/sb1.jpg Bookmark http://www.mgfcar.de/schedules/ for access to the diagrams and link to the fuse list. I think analysis will be much easier then with that mad sticker. btw, the 40Amp Fuse could cause some sourcing troubles. >Special design fuse< Regards Dieter PS. wearing a cap this night to protect the scalp ;) |
| Dieter K. |
| >Batter then nothing, errr ... and so on. Ooops, I think I should really use a spell checker. Anyway, should make sense with swapping a's and e's and some additional imagination. |
| Dieter K. |
| Ok I give in and typed like mad. Could not sleep and *did a brief description* how it should work. If anyone finds failures, pleasse keep them... LOL ---------------------------- LH and RH headlamp units contain individual bulbs for headlamp main and dipped beams, and for the side lamps. Tail lamp bulbs are incorporated into the tail lamp units. Rear number plate illumination is provided by two lamps installed in the rear bumper. Operation of the headlamps and side lamps is controlled by a lighting switch in the steering column LH stalk. A ’lights on’ alarm is installed to prevent the lights being inadvertently left on when the vehicle is parked. How it should operate: Power supplies Fuse 7 in the under bonnet fuse box supplies a permanent feed to the multi function ECU (MFU) on a Purple-Brown wire. Fusible link 1 in the under bonnet fuse box supplies two permanent feeds to the lighting switch on brown wires. Fusible link 4 in the under bonnet fuse box supplies a permanent feed to the ignition switch on a Brown-Purple wire. When the ignition switch is turned to position II, the feed is supplied to fuse 1 in the passenger compartment fuse box on a Black-Yellow wire. Fuse 1 supplies the feed to the multi function ECU (MFU) on a Green wire. Side lamps Turning the lighting switch to the side lamps position connects a feed from the lighting switch to fuses 7 and 8 of the passenger compartment fuse box on Red wires. Fuse 7 feeds the RH side lamp and the RH tail lamp on Red-Orange wires. Fuse 8 feeds the LH side lamp, LH tail lamp, LH rear number plate lamp and RH rear number plate lamp on Red-Black wires. All of the lamps are earthed on Black wires and illuminate. Headlamps Dipped beam Turning the lighting switch to the headlamps position operates the side lamps as detailed above and also connects a feed from the lighting switch to fuses 10 and 11 of the passenger compartment fuse box on a Blue-Pink wire. Fuse 10 feeds the LH headlamp dipped beam on a Blue-Pink wire. Fuse 11 (C0585) feeds the RH headlamp dipped beam on a Blue-Black wire. Both headlamp dipped beams are earthed on the same Black wires as the side lamps and illuminate. Main beam Selecting main beam connects a feed from the lighting switch to fuses 21 and 22 of the satellite fuse box on a Blue-White wire. Fuse 21 feeds the RH headlamp main beam on a Blue-Green wire. Fuse 22 feeds the LH headlamp main beam on a Blue-Slate wire. Both headlamp main beams are earthed on the same Black wires as the side lamps and illuminate. Main beam flash Operating the main beam flash bypasses the main beam contacts in the lighting switch and operates the main beam circuits as detailed above. When the switch is released the circuit is broken and the headlamp main beams are extinguished. Lights on alarm The multi function ECU (MFU) operates an integral warning sounder if the lights are on with the ignition off and the driver’s door open. When the side lamps or headlamps are on, the multi function ECU receives a feed from fuse 8 of the passenger compartment fuse box on a RB wire. When the ignition switch is in position II, the multi function ECU receives a feed from fuse 1 of the passenger compartment fuse box on a Green wire. When the driver’s door opens, the Purple-White wire (LHD models) or Purple-Slate wire (RHD models), between the multi function ECU and the driver’s door lock motor, is connected to earth on the Black wire between the driver’s door lock motor and an earth point (on LHD models) or earth header (on RHD models). While the driver’s door is open, if the side lamps or headlamps are on and the ignition switch is not in position II, the multi function ECU switches the warning sounder to earth on a Black wire connected to an earth header and the warning sounder operates. -------------- Can anyone translate to german 4my webside ?.. ? ROFL ;) |

| So the question is, where are fuses 21 and 22 on the satellite fuse box? I'll have a wee scout around and see if I can find 'em tomorrow. Looking at the description of the fuses in the owner's manual (or the lack of a specified location), I'm still assuming that it's located under the dash-board somewhere. Good hunting! Leigh |
| Leigh |
| Dieter/Anyone, http://www.mgfcar.de/schedules/sb26.jpg OK, the satellite fuse box is what Steve's after. Anyone know where it is? Cheers! |
| Leigh |
| Take it along to the MGR dealer and get them to sort it out otherwise you sound like you may end up loosing your hair!. You might be lucky, they might change the fuses there and then free of charge. kind regards bryan B4 LGW |

| The satellite fuse box (SFB) is sited right next to the passenger compartment fuse box (PFB); the SFB is effectively attached to the side of the PFB. The PFB has fuses 1-18 and relay 1 (cigar lighter). Fuse 25 (SRS) is off to the left. The SFB has fuses 19-24, 19 being the bottom one. Fuse 26 (f fogs) is mounted just to the right of the SFB. Relays 2 (window), 3 (engine fan), 4 (HRW) are mounted to the right of the SFB; 4 being the bottom one. Fuses 21 and 22 are the central two fuses in the bank of fuses in the SFB. OK? |
| Ian Walker |
| Dieter, Many thanks for the wiring details..I promise to print off and put somewhere safe... Ian.....where is the PFB ?? Is this in addition to the one under the steering wheel and the one under the bonnet ?? IF so, I could not find it anywhere. I think I may have to bite the bullet and pop down to my local friendly MGR dealer... Thanks guys |
| Steve |
| PFB I take to mean the main fuse box (i.e. the one under the steering wheel), which is on the passenger side on LHD cars, but under the steering wheel on RHD cars. Indeed if you look at your pic, fuses 1 - 18 are shown on the diagram. Remeber passenger compartment means where we sit, not on the passenger side of the interior. Comparing: http://www.angelfire.com/my/crapauction/MG/index.html With: http://www.mgfcar.de/schedules/sb26.jpg and with Ian's description, that puts the satellite fuses back in the 'black hole' between the 1-18 fuse panel and the relays, as I said above. However, Ian seems to imply that the fuses are down the RHS length of the main fuse box, so have a look down there at the side. Might be tricky to get in there though. I'll have a look this afternoon and see if I can see them. Leigh |
| Leigh |
| Steve, I have a picture of my car's fusebox and when I compare it with yours it is indeed missing the little panel with the 6 fuses which should be in the black hole between the big fusebox and the 3 relays (as Leigh says above). I will try and email you the picture. My guess is that your little panel got lost behind the main fusebox, get a torch and have a good look back there. Spyros |
| Spyros Papageorghiou |
| Anyone out there with the manual that can have a look and find the position of the satelite fuse board? I suspect it's not attached to anything, so may have 'moved' slightly. It may actually be a better idea to get on the floor and look up at the fuse box from behind, rather than with the fuse box open. HTH, Leigh |
| Leigh |
| I think now we got it. SFB must be on the left of the PFB on both, RHD & LHD cars, not drawn on this pic. http://www.mgfcar.de/fuse/Fuses_2.jpg (pic courtesy Steve, but made smaller) I just found this one in my picture archive on the HD. http://www.mgfcar.de/fuse/Dcp_4668.jpg (notice the LHD car different relay location far on the left.) Satellite means in this case, the fuse bulk is clamped to the panel. Kind of *swallow-joint*. May be the case got loose and pushed off and disappeared to the rear. Would be nice to get a full picture of the RHD PFB including SFB and relays :) To complete http://www.mgfcar.de/schedules/fuses.htm (the one missing there) Regards Dieter |
| Dieter K. |
| "Would be nice to get a full picture of the RHD PFB including SFB and relays :) To complete http://www.mgfcar.de/schedules/fuses.htm (the one missing there)" Dieter, you have mail; pictures from my 2002 MGTF clearly showing PFB, the SFB and the relays. As said above it is under a flap about 35cm x 15cm in the dash below the steering wheel/column. The data in my post above was taken from the MGTF electrical manual. I assume from the above posts the MGF is not significantly different. regards, Ian |
| Ian Walker |
| Comparing Dieter's LHD picture http://www.mgfcar.de/fuse/Dcp_4668.jpg with my RHD TF pictures the SFB is on the Right of the PFB with a LHD F? the SFB is on the Left of the PFB. Ian |
| Ian Walker |
| By godness, one of the most confusing threads since month ;) Ian, many thanks fort the 'complete' pix. I just reworked the site. The short words explanation and HT relais mark will be enhanced later. Stop, closed down. Last from me. @ Steve, good luck on finding the lost fuse box ;) I suggest to remove the fusepanel lid for easier access, but at first disconnect the battery. Two Philips bolts to be loosened, then pull off the flap. Unbolt the two upper hexagon nuts holding the sheet metal in place and careful lower the panel. The 'lost' fuse bulk should by woving around there anywhere. You should as well be able to but it back on the right of the panel where it should be. Cheers Dieter |
| Dieter K. |
| Hooorah ! I wasnt going mad ! At least I now know that there should be 6 extra fuses ! Right...Im going to have a few cups of strong coffee then start dismantling the F. Thanks again guys for all your help... I'll take some pictures while im working and post them later Steve. |
| Steve |
| Guys !....finally resolved the problem. The 'extra' 6 fuses had somehow worked their way right down behind the carpet underneath the pedals. I spotted a bunch of wires and pulled them out to reveal the 6 fuses......both main beam fuses had fallen out. All back in place now and lights working fine. My guess would be that this extra fuse panel was never fixed in place to start with.. Thanks again for everyones help. If you are interested, I have taken a few more foto's http://www.angelfire.com/my/crapauction/MG/sorted.html Steve. |
| Steve |
| >My guess would be that this extra fuse panel was never fixed in place to start with.. I think no guess, but the truth. Would be no reason for any service personnell at dealers to remove and later forgetting it down there. May be Mr Lucas shocked the guy at the manufacturing line, so he forgot it. Or someone forgot to train the worker from new after a works break or visit to the toilet ;) Anyway, nice to see you fixing the problem now. Cheers Dieter PS. I steal the pictures, may I ? :-) |
| Dieter K. |
| Dieter, Feel free to take whatever pictures you want..... steve |
| Steve |
| Well done steve. One other worrying aspect of this is that they could have dropped down onto the brake pedal possibly causing a problem when braking. I'll definately be making sure mine are now properly in place! Leigh |
| Leigh |
| Mystery solved! All's well that ends well! Have a happy New Year everyone Ian |
