My bike has had a weird condition. Its had it since I have owned it and I have no idea what it is. Every once in a while (like once every 3 or 4 months), the blinkers will start to flash in a goofy way while I am riding. It doesn't do it very often at all, and its only done it a cruising speeds. What will happen is the turn signals will start flashing like the hazards are on but instead of all 4 flashing at the same time they will switch from left to right, over and over again till I hit the turn signal buttons. Then they go back to normal. Its very rare, like I said, but it will do it every so often. Has anyone ever heard of such a thing????

 

Mine will occasionally start flashing while the bike is sitting there at an idle. I push either button and it'll stop and go back to normal operation. I'd guess it's just a faulty module and in my case it doesn't bother me but in your case I could see where it might get other drivers freaked out...

 

I'll go with the module. It's an electronic device. I'd also check the connections to it.......Maybe take it apart and use some contact cleaner.

 

I just had to get mine checked out for the lights going crazy on me as well. The hazards would flash rapidly and dim, come to find out there is a wiring harness mounted under my back tire that came lose and depending on how I hit a bump, it would hit the back tire and go into a freak out mode.

 

Thanks guys. I might start looking at stuff tomorrow. Supposed to rain anyways, might as well work on the bike.

 

A little something I found on my 91 flhs.... the sockets are grounded to the housings... which caused my module to take a puke. Also corroded dielectric grease in the sockets... Fix was clean sockets and wire ground to the housings.

I also did a voltage drop test, and found that I was loosing 2 volts to the ignition switch. took it out to find oil on the back causing my resistance. Module is shot, in turn for time being until I get another, I wired in 2 flashers, one per side to keep me on the road til the module comes in. ordering monday. I'd start with checking voltage @ the socket and compare it to voltage from the battery. anything more than 1/2 volt is bad. and have fun chasing that gremlin!

 

Thanks!
