Motorcycle Repair: charging issue on 1994 Sportster, rotor stator, harley manual

Question
I have a 1994 Sportster XLH 1200 with 7500 original miles on it. I drove it for several hundred miles after I got it, and one day after trying to restart it, the engine would barely turn over. We pop started the bike to get it back, and on the way home the headlight worked but none of the other lights or turn signals worked. When we got it back, the battery was dead. I was able to charge it up and drive it again, but could only get about 70 miles before the battery became dead.

I got the factory Harley manual and did some tests on the electrical system. All the tests seem up to specs, except that when running, I put a volt meter on the battery terminals and got a reading under 12 volts (like 11.x or something). Could it be a bad battery that the bike just won't charge or a problem with the rotor/stator or the regulator? Would it be common for a bike that has 7500 original miles to have a bad stator or regulator? What would be your honest opinion? I have not had the battery tested but I am able to charge it at 2 amps (although I don't get a fully charge indication on my charger after 12-15 hours) and start the bike..

Answer
First, have the battery tested. You might have a bad cell in it. Once you know the battery is good then test the stator. Do the OHMs test as well as the voltage test. If the stator tests ok then the regulator is bad
Electronic parts can fail at anytime, but it is not common at 7500 miles
Good luck and happy riding
