I am tryng to get my 50 Olds 88 on the road but have an issue charging the battery. I have replaced all the wiring under the hood and have cleaned the regulator points as described in the manual. Basically at fast idle the generator puts out roughly 6.5 volts (Chcked at regulator). When headlights are on it drops below 6v. At idle with all electic off it barely hits 6v and goes in the low 5v's with hedlights on.
So reving the engine increases output but never above 6.5v. At idle I can see the speed of my blinkers drops by half and speed up when I rev the engine.
The manual says if you have low output you can isloate to a generator problem if you ground the "F" terminal it should cause the generator to increase output. I tried several times but never saw an increase.. I checked the brushes which look good to me and checked to ensure the connections on the two wires from the generator were clean and tight.
Trying to avoid a trip to the shop to have the generator checked in case it's something simple.
