Electronic Transistorized Alternator voltage Regulator test

I guess if you think there is no information, you have not read many of my posts.

While that pdf is a quick test, for many guys on here that don't really understand this, there is a LOT left out

Example. What if the jumper test does NOT cause a charge? You go out buy an alternator, and guess what? It STILL doesn't charge!! WHY!!?

Several reasons.........

Maybe there's a break in the alternator field 12V supply, and the field is not getting 12V

Maybe there's a problem in the green wire, or a break right in the regulator connector

Maybe there's a problem in the output circuit of the alternator, and it essentially is no longer hooked to the battery

This is just a few. There are others.

One BIG BIG thing that causes guys grief with these systems, both charging and ignition, is that BOTH the ignition ECU AND the regulator MUST BE grounded. Because of the "crappy" mounting system originally used (firewall "threads") this can be no joke.
