Not sure that this is germane but it might be -

I had a string of failures of cheap Chinese Denso knockoff alternators on my HP car. The stators (fixed windings inside the case) were vibrating loose.

My local generator/alternator/starter rebuild shop (a dying breed I think) took a new one apart and reassembled it using more or better epoxy. They seemed quite familiar with what was happening and how to prevent. No more failures.

My problem with the Isuzu starters (spridget) was the wiring inside the solenoid breaking from vibration. I seem to have fixed that with application of gobs of Goop, available at your hardware and Home Depot. Seems to hold everything in place, and it's a simple matter to remove the rear solenoid cover, dab in the goop and seal it up again.

So that's what I need to do. Every now and then, it just quits working. Another thing to fix on my Spridget. Thanks Mike.

Are you guys saying GOOP like the hand cleaner? I just had a "brand new" gear reduction starter die after only about 14 starts last race weekend. Had to be push started then sat on grid with the motor running for about 25 mins. while the track was cleared from an incident. Luckily, it didn't over heat.
Mine is from BRITISH STARTERS. Replacement one is on the way but I'm worried the same thing is going to happen.

They're referring to a non-conductive epoxy of some sort.

The issue is thing buzzes and vibrates which fatigues the wires themselves, causing them to break loose- typically right at connection point. The solution is to secure the internal wiring somehow. a little "rubbery goop" secures and stops the fatigue of the wires.

I don't know if RTV silicone would be acceptable since it emits acetic acid (vinegar) when curing, and that stuff is conductive. Permatex website states that their "ultra copper" RTV is non-conductive, so I *assume* everything would be fine with any RTV once the stuff is allowed to cure.

Other options are to use an electrical potting compound of some sort, which is typically again a 2-part epoxy that's mixed and poured into something to protect and seal it.
