Default TSM/Turn signal module

I had a left rear blinker issue. All other 3 blinkers worked as normal. I fixed the broken wire, now I have no blinkers? Not sure what could have happened, but am wondering if the TSM is bad now? Do you check it by seeing if there is 12v in, and hit one of the blinker buttons and if there is no pulse out is that mean it is bad? 2010 Fatboy Lo, thanks

I don't know how the blinkers work but for my bikes the starter and igniton enable from the TSM is done by grounding signal.

But think about it, you fixed a broken wire and still doesn't work. Something ain't right. Recheck your work. Ohm pins form end to end.

Broken wire and bad TSM is a lot.

I would buy harley TSM it works with your check engine light, to my knowldege, on my older bikes it does not.

I found the issue, the "accessory fuse" was blown. I must have done that fixing the wire to the blinker. Just to let you know, the 2010 fatboy blinkers are powered by that fuse.

FWIW ... The Custom Dynamics TSM will require a Technoresearch Tuner to complete the installation
