I have a 2010 Fatboy, just changed the the bulbs and cheked all the fuses. Hazard flashers work fine. When I signal right or left the the hazards blink, any suggestions??
 
Welcome to The Forum, what is the reason changing the bulbs? Did you use the correct bulbs? Do you have any modifications to the lights?
 
The bulbs looked good, I figured that would be the least expensive trail and error replacement options. I put the original bulbs back in. I disconnected the wire harness to the rear signals and the front signals worked just fine. Puzzled............. no modifications, FOB or security alarm on bike.
 
Sounds like you may have the rear running/turn signal optional converter installed?

Or maybe an under rear fender cable damage from tire?
 
Also perform a WOW test and see if there are any codes. If there are any wiring shorts, you will probably have a stored code for a TSM malfunction.
