hi frame if you have some done wiring hopefully you have a multimeter if not there bout 20bucks at boating stores.set it to volts then with engine off check the battery voltage should be 11 to 12 volts.then start engine and do same test and if alternator (stator) is working and connected right it now should read between 13v to 14.6 volts if so charging working.if not you have problem ie:short somewhere or stator not working or blown fuse,or faulty rectifyer,good luck
