Randy Brian Posted June 6, 2018 Report Posted June 6, 2018 Hey guy's, My battery started discharging all of a sudden on morning, so I cleaned all connections, no help. tested the generator by grounding field term and supplying juice to the positive term on gen and it spins and when you disconnect the field wire it goes faster so that is supposed to mean the gen is working, not. then I replaced the voltage regulator with a new one and jumped a to b for setting polarity and nothing still discharge, I hooked a wire to the case bolt and to the ground post of batt thinking it was not grounding but nothing helps still discharging, if I unhook the neg batt post while running it dies. what am I missing?

Randy Have you tried disconnecting a battery cable while it's running? Sometimes the gauges go bad. If it continues to run with the battery cable removed,it's charging. Quote
jeffsunzeri Posted June 6, 2018 Report Posted June 6, 2018 (edited) Check battery voltage, then start the car, check the output voltage at the generator, then at the regulator. You need to see voltage greater than battery voltage. Edited June 6, 2018 by jeffsunzeri Forgot step 1. Quote
Randy Brian Posted June 7, 2018 Author Report Posted June 7, 2018 If I unhook the neg cable while running it dies.... Voltage was all over the place when checked while running, I took the gen apart and it is a mess inside beyond it;s worth, do any of you know about a 6volt altenator that will work for my car, I found a bunch of stuff on them for gm and ford. I don't think my gauge would work with one of those. Quote
