I have a guy that was doing some wiring on his FB and he thinks he may have fried his TSSM because he forgot to disconect the battery first. He said one of his signals doesn't blink (the other one does) but the run light does work on the non blinker. So I told him to remove the run-turn module. So he checked all his fuses & Fob battery, and removed the run turn stop module and it didnt change anything. He also says he tried to start the bike, hits the run button and the fuel pump runs but no yellow engine light and engine won't turn over. So I'm asking you guys if you have any suggestions for him. I have the following questions. (I'm pretty sure he has switched the bulbs but I will have to ask him again) Can one signal still work if the TSSM is fried ? Is there any way to test the TSSM to see if it is failed ?
