82 750 nighthawk with 4,500 miles on it. It hasn't been tagged since 03. I've put 2 batteries on it. One just kept going dead. I checked the rotor and it's sitting on 5.2 ohms. The stator tested fine but they both looked rusty. I cleaned them up. I've only rode this bike 10 miles since I got it. I took the battery to get it charged and it came back with 11.5 volts and I still had to jump it off. Revving it to 5,000 rpm, it doesn't go over 13 volts. I checked the brushes and they aren't worn but I have to scratch and poke to get a reading. This bike has sat for 20 years until I got it last month.
Someone has had the stator off before because the gasket is gone and it was rusty inside. Is the stator the problem? Maybe the brushes? I just don't understand why I have these charging problems with a bike with such low miles... I'm lost!!!!
