What year is bike?

[oldskool]

the bike is a 1993 1200 sportster! haven't had any luck so far! I have continuity through the wire that goes through the fender and up to the switch!The only thing I've found is I do not get battery volts at turn signal with red probe on wire end that the bulb hit's in bulb socket? and blk probe on rivet in socket! I get battery volts on other side doing this!???

I think your turn signal modual is failed on one side this is the unit that makes them flash,under seat anyway ,I have swiched wires from one side to other to test the whole circuit for proper working ,you could just plug the TSM in to a friends bike and see if it acts the same
