Bill - that's where i am at in my thoughts as well. but the wiring is very simple. Black from Battery to one side of the ammeter, red from other side of ammeter to BAT terminal on regulator (which continues on to horn relay). not much to go wrong there. when a load is put on the system, the proper discharge is shown on the ammeter. with the engine running, no charge is indicated - and I believe it because the voltage back at the battery never changes. it stays at 12.6v.

i am going to ground the field terminal to prove the generator produces in excess of ~13v. if it does, i am going to concentrate on the regulator.

I searched the forum back 15 years and "failure to charge" problems come up a lot. its usually a regulator problem, so that also makes me think my problem is there...

thanks for your reply.
