That's not going to matter much if his charging system isn't working, other than to give him enough juice to get stranded 30 miles from home.

 

If you are going to get stranded, you might as well do it right.

 

i have a freinds with a sportster bible and i ran a test on my rectifier.. it failed.. i replaced it and everything is perfect, voltage at the battery is right on... so it was the rectifier... thanks for everyone input..

Could be that you have a bad battery cable. Disconnect the battery and check the battery cables with an ohm meter. Should have less than one ohm resistance on both cables. Or use a voltmeter with the battery installed and check for a voltage drop. The higher the voltage drop the worse the cable. Either way put your test leads on either end of the battery cable(s). Check one cable at a time. My '04 XLR snapped the lug on the ground cable where it bolts onto the top of the engine cases. Good Luck!
