Voltage regulator soup

[FranksCoronet]

Hey guys, a few weeks ago I noticed my voltage regulator on my 70 coronet turning itself into soup, still runs fine but I got a replacement NOS one that I'm going to put on soon. Obviously I dont want this to happen again, so what causes something like this? What can I do to prevent it? It was fine before I took it on the annual pilgrimage to Carlisle in July.

I've never seen one ooze out it's innards; now I have.

I suspect a cheap quality insulating material.

I only watched the first 2 minutes so far (I'll watch the rest later) but it made my realize, a few months ago I removed the original alternator and replaced it! I'll start there. Thanks!!

Glad it helped you. It is a good video to have in your file.

why does it not show the square back alternator?

Was there 2 different ones for 70?

1970 was the first year for the isolated field alternator, but they were round backs.
