PhilJohnson Posted April 3, 2011 Report Share Posted April 3, 2011 My 51 Plymouth's charging system wasn't working right. The needle was bouncing back and forth from 0 to 40/50 amps. Finally the generator quit charging. I filed the points in the voltage regulator (they looked pretty bad) and adjusted one of the point gaps to the point where the needle quit bouncing. What is normal amount of amperage for a stock generator at idle and and speed? It is 15-20 amps at idle and around 40-50 amps at cruising speed. I am in the dark, sorta guessing how this stuff works. Is there anything I missed or need to do? Quote Link to comment Share on other sites More sharing options...
greg g Posted April 3, 2011 Report Share Posted April 3, 2011 Depends on the charge state of the battery. A fully charged battery may take need nothing after a few minutes of idle to replace what charge was used to start the car. Quote Link to comment Share on other sites More sharing options...
