Turn/brake bulb problem help!!

My rear turn signals on my 08 street bob were converted to dual use with the turn/brake module. Everythig has been working fine for over a year. Then the idiot warning came on the left side (blinking fast). It looked like I just had a bad bulb. However the bulb is fine and I checked the socket for power. It lights up the tester with the turn and with the brake. What gives??? You all are always a big help thanks in advance.

I just had a bad turn sig experience, turned out to be the TSM was faulty.

Check for error codes before you start pulling things apart, could save you a lotta time chasing phantom problems.

Good luck

If you have one of those Turn signal/Brake light modules in your bike take that out and hook it the stock connectors back together and see if your blinkers work like they should stock. If they do then its your module,

I just replaced mine, I hit a big pot hole the other and it went out on me...

I will try that. I just thought it was weird there was power there but the bulb won't light up.

Here is a link to a thread I started about how to check the codes on your bike.

In my accident my right rear signal light was broken off. When repaired the module did not work. I replaced module and works fine. I think the sudden loss of power fries the units. Like you said a large bump or impact could damage the units.
