MG Midget and Sprite Technical - Simonbbc electronic ignition

I'm just trying to fit my new electonic ignition kit from Simonbbc. Delivery very quick and fitting looks easy. However the two wires that run from the sensor unit to the fitting which slides into the distributor casing are too short.

Has anyone else had this trouble

I've emailed the company to ask there advice.

If they don't sort this out could I simply lengthen the wires with two spade/ bullett connectors within the distributor casing.
T Wainwright

What an idiot I am.

The plastic thing that slots into the distributor casing can slide down the wires.

Heres a picture, at £24 I though it would be worth the risk. I will let you know if it actually works.

cheers

I'll be interested to hear your findings T. I saw these advertised on ebay and was wondering if they were any good. Do you need to make any other changes ini the ignition system?

I find them very good here and now stock them here in Australia at the Classic Car Clinic

Sadly, they are not as cheap as they are in the UK, but still very reasonable....!

Looks a neat unit - just check wire lengths within dizzy not strained on full advance.

I put one on last year and it worked great. I seem to remember a bit of cutting & lengthening of wires but I was also doing a lot of other wire tidying up at the same time. Best part is I've not had to look at it since ;-)

What exactly is it? A replacement for the points, right? Is it a hall sensor? Does it need a special rotor arm too?

A replacement for the points, right?

Yes.

Is it a hall sensor?

Yes.

Does it need a special rotor arm too?

Yes (supplied with kit).


I've used one of these kits on my MGB for the past 14 months and 11,000 miles and not had a single problem. It's every bit as good as the (much) more expensive Aldon/pertronix Ignitor units.

Whichever unit you go for, an electronic points replacement is well worth the investment - expect easier starting, smoother running & idling with a consequent improvement in MPG. Easy to fit and easy to remove should you want to revert back to a point-based system, at £24 they're cheap enough to carry a spare unit in the car if you're worried about being stuck roadside in the event of a failure.

I'm with Richard... just make sure you can get full movement of the advance plate.

And having said that, I've just written a note to myself to check my own PerTronix installation when I get home. Over the past little while, my midget's acceleration has leveled off at around 65 or 70 mph, and it won't go any faster. Runs brilliantly otherwise, and all its vital signs look spot-on. But if advance is being held back by short wires, that would be good to know.

Cheers,

I fitted one of these to mine whilst trying to sort ignition problems. Works just as well as the Lumenition that was on there as far as I can tell.

Mine did not use a special rotor arm though, just a plastic ring fitted with magnets that fits over the cam, under a standard rotor arm.
G Hawkins

It's a good idea to tie a small nylon cable tie around the wire to serve as a cable grip on the inside of the plastic clip that passes through the side of the distributor, this will prevent you accidentally pulling the cable tight when you work under the bonnet near the distributor.
Mike

I totally agree with Mike that these are every bit as good as the Pertronix kits.
Nick Sayle

I have also fitted one of these units very easy to do and good value although my car is still not on the road yet. Saving up for some paint work to be done.

There is one issue I see that you need to give attention to.

where the wires go into the chip, at that point, the wires will want to "hinge" as the advance moves back and forth the wires move back and forth at the entrance to the chip, over time the intallation will break down and it will ground to the dissy and eentually let the blue smoke out of the chip, but not before missing alot esp. under load (acceleration) for 2-3000 miles

what I did on my 2nd Pretronix (and thats exactly what this is) I put heat shrink over the wires and repositioned further up the wires with a small zip tie where the "hinging" takes place... basically any place to "Hinge" is better then where the wires attach to the chip

just my personal experiance... btw it takes awhile for this to happen so not like you have to deal with it in the next 24 hours.

I Pickering,

I may be wrong but im pretty sure paint alone wont fix that big hole in the side of your car....LOL

Prop

you might want to get a door first :P
or are you going for the buggy look ;)
Onno Könemann

Are you sure thats a special rotor bug?

It looks like a stock rotor bug with a special megnetic disk under the rotor bug like on the pertronix set up

Hi 5 onno...LOL

It's definitely a proprietary rotor arm Prop, the top looks like a standard rotor, but the magnet ring is integral unlike the Pertronix. Replacements are cheap and available though, I've not bothered with the Powermax rotor as it seems to work fine with the standard kit.

Ian - I'd go a bit easier on the rubbing compound next time, you only need to remove the surface of the paint, or are you preparing for a bullion hoist?

Ladies and gentlemen THE DOOR!!!!!!!!

"It's definitely a proprietary rotor arm Prop"

The kit for the 25D Midget dissy is definitely a standard rotor arm and separate ring.
G Hawkins

My bad G, the 45D uses a single piece rotor.

BTW, if anyone sees a similar electronic ignition unit with a blue casing - avoid! I bought one from a LandRover dealer for about £5 and initially thought I'd found a bargain, it worked brilliantly for a couple of weeks. Unfortunately it did not like a hot engine bay and the car would lose power almost to the point of stalling once the engine got to working temperature. Curiously if a put a small amount of load on the electric system e.g the indicators, the engine would liven up again, also after 5-10 minutes cooling it would work OK again. These were the initial units sold by SimonBBC, the replacement 'red' modules do not suffer this problem.

The blue units (manufactured/supplied by Britpart) were withdrawn, but I still see them available online for discount prices.
Mike

I bought his bundle with the 12v coil - works really well. The 45D has a special rotor arm whilst the 25D has a ring beneath the standard rotor arm.
It solved a very annoying misfire for me and took about 5 mins to install.
Best value part so far I would say!

ps No I'm not on commission
Andrew Dunn

I have got a Lumenition Optronic set up I have never got around to putting on the car that someoone gave me. Is it worth it? This system seem simpler, are there any advantages/disadvantages(apart from spending £24)
m fairclough

"The 45D has a special rotor arm whilst the 25D has a ring beneath the standard rotor arm"

I installed one last week in my 45D and used the seperate magnetic ring in combination with my rotor 'cause I didn't want to use the supplied rotor with ring because it is a riveted rotor.

So I put in a 25D ring in? It works ok, except I still have pinging on pick up between 2K - 3K revs.
