headlight power drain
Hello, I'll get down to intro real soon but for now... I bought an 89 VN750 with 30k miles that didn't charge. I just installed a Tim Parrot re-wound stator, coupled with Shindengen (MOSFET) relocated about an inch over JB. Conducted test on stator; she works perfect (not grounding & idle = 31-32 Vac & 3k rpms = 60-70+ Vac.
My problem: she doesn't charge correctly once I connect the headlight (JB yellow to stator leg), I'm barely getting 13v (DC). But, when I connect just the stator to the mosfet, (WITHOUT the yellow headlight relay wire in the JB) I get an awsome 14.27+v, but of course, no headlight. So I moved the Blue wire of the JB 8-connector to the empty slot (yes, I've done extensive research on this site) and now I have headlight upon turn of key but... only 13.5v (cold eng). This is unacceptable voltage for a cold engine, and I'm not too happy with this blue wire rearrangement (bypassing trigger relay/3 diodes of JB).
What/where/how do I look for this power drain? short? Something is not right. why is she draining nearly a whole volt upon teeing off the headlight?
