I have a 1988 FLHTC. I moved the battery from the right side to under the seat. The only wires moved are the battery cables. My head light and tail light began blinking on and off after the battery move. The console light remains on. I have a Badlands rear light controller installed, so my turn signals do not operate unless the lights are on. When the lights are blinking I think I hear the flasher clicking on and off. All lights worked perfectly for the first 150 miles after the battery relocation. Any suggestions on what I should try to solve this problem? Could it be a bad Badlands module or a bad flasher? I can't think of any reason why the flasher should control the running lights.


Any help you guys can give me will be appreciated.

 

I knew that it had to be related to the lighting system. I isolated the problem by disconnecting the Badlands module. That left the front end of the bike. I removed the headlight and checked the wiring behind it. While moving things around in there to be able to get to the connectors to check for shorts to ground, one wire was sparking when it moved. The hot wire going to the right turn signal/running light had a spot about 1/16 missing insulation. Fixed the wire and all lights working as they should. I do not know how that one wire could make them all blink on and off, the flasher would even sound.

 

Well done for sorting it out. You have proved my theory that many electrical problems are actually mechanical - a wire touching something it didn't oughta!
