`99 Road King, left rear blinker intermitting, thought to be a corroded connection at bulb, then right brinker intermit, sometimes it would work and sometimes not, thought to be thumb switch as I can put pressure on it and it would sometimes work.
Then last night I head home and Ive no lights at all except for gauge? Replaced blown 15amp fuse and right rear run/turn light is staying on bright (brake mode).
Could the run/ turn module be defective? What else could it be??

 

just unplug the module and go back to stock and see if that fixs the problem , if not start checking plugs for corosion or bad ground

 

Look under the rear fender, had a friend that had that issue and the wire harness that runs under the rear fender had been rubbed by the rear tire and was intermittently shorting out.

 

sounds like a short to me

 

well... found the culprit.
Seems we were all right, there was a short, and it was in the module. Seems last time some genius (me) changed the seats, the wiring on the module got pinched, eventually wearing thru, shorting the module and blowing the fuse. Works great with no module, apparently I popped a diode in it? Thanks for the help fellas.

 

damm gremlins , glad ya found it , easy fix
