BARTAMOS......naw, I kinda like the generator / regulator. Have you been to an auto electric shop lately and seen the pile of scrap alternators waiting for diodes ?

WRENCHBENDER...battery voltage with engine running is 13.9. I opened the ammeter. There is no shunt in there, just a brass bus bar. Nothing to break.

JON G..... I pulled out all the fuses to isolate other electrical stuff. With all the fuses out, the ammeter was still full +. I'll keep poking around in the un-fused areas.
