Hey everyone I am new as well. I have an 81 xs650 I just bought and sounds like it might have the same issue. When the battery is charged up it starts and runs great but as soon as he battery dies, nothing. When I hook a battery jumper to the cables it starts right up but dies just 10 seconds after. Could this be the regulator? Also I heard some say the wrench test to check for magnetic field. Do it just see if it has that and that means e alternator is working? I am a big car guy but newer into bikes. Any help would be greatly appreciated.
