MG TD TF 1500 - Dead Ignition Solution


I have read several times of loss of ignition because the tach drive gear box vibrated down and grounded out the dizzy primary connection. A zero cost solution is to use one of those plastic caps that are found on new electronics equipment. I picked one that fit tightly, notched the side to clear the wire terminal and pressed it on over the terminal nut. May prevent an annoying stoppage. Apologies it I stole someone's idea.

Another popular fix is to ad a bracket as shown.
Has not been an issue since I did this.

isn't it easier to reindex the distributor so the terminal is on the side opposite the tach drive. regards, tom

In answer to your question, no! My fix took 3 minutes including digging through the miscellaneous plastic parts box. Also it is easily removed for maintenance or really picky show judges. However I like Dave's bracket. Nice neat job.

Well, indeed you do learn something new here every day! My dizzy was installed (by PO) backwards like Tom suggests above. Maybe that was the reason! That said, I can tell you from personal experience that getting to that terminal on the other side if you have to is not fun!! (Don't ask me how I know!). I have it on my to-do list to turn it back to specs for that reason. However, this thread may make me rethink that idea. Humm...
Thanks Jim & Tom!

Very nice and approximately the same $$ as mine.

I simply fitted a nylon washer between the coupler and the boss on the generator. It stopped it from rotating.

Mabey the fact that it's eary in the morning,,,, but can you post a picture?? I can't figure out what these are;
>>plastic caps that are found on new electronics equipment.<<



I will try to get a photo in a day or so. In the mean time the plastic caps I am referring to are usually on coax connectors on new TVs VCRs DVD players etc. You can also find them on small plumbing fittings refrigerators ice-makers to keep dirt out of the lines until installation. Also on new or rebuilt brake cylinders and master cylinders. Email me with an address and I will send you one. I have accumulated a few over the years.
