VS: Both turn signal light flashes at the same time

On my VS I have a problem. When I activate the turn signal switch, both the left and the right turn lights flashes at the same time (like a modern warning hazard light). I have checked all the grounds and all the wiring, but everything seems fine (no corrosion)

Any thoughts on what to do?

take it back to Kirk, or call him. If it is a 2007 VS, don't let it be your problem.

Did it just pop up now? I was thinking grounds also.

It should be something simple, like a ground or a defective turn signal switch (?). Call Kirk; he should be able to help you sort through the problem.

Assuming everything used to work OK, and this is new problem, how do all your OTHER lights work? Front and rear? If all else is normal, I agree switch is first look.

My late 2006 turn switch developed problems and when it was pulled out at Kirk's shop
it had a hole burned in the side the size of a penny.

It's most likely a faulty ground. Try running a temporay jumper to a good grounding source. If that works, you know you need to make a permanent fix either by running a new wire to a good grounding source or checking for where the fault may be. Lot's of fiberglass makes it easy to have ground problems.

Thanks for your input.

I'm living in Denmark, so I'm 5.000 miles from the helping hands of Kirk, but I might call him for help anyway.

All the other lights are working okay, so I will have a look at the turn switch.
