Need assistance - Turn signals won't work beyond 65mph

[prizepup]

Not sure what the problem is but my turn signals work fine if I ride up to 65mph. However, they won't function at all once hit about 67mph and beyond. Has anyone had this problem? It may be a vibration thing but it's odd that my signal lights seems to have such a consistent and defined cut-off. Any helpful advice on fixing this problem would be appreciated. And no, staying 65mph is not a solution I'll entertain. Just wanna make sure that's clear right upfront.

Just the fronts or the back ones two?

Thats an easy fix, just stay under 65MPH.

I think you got one of them Government regulated BDMs..

If you travel at the speed of light and turn the lights on, what happens? Nothin. Yea you're going to fast

not sure about you set up but if you were to unhook the speedo and give it a try it might allow you to rule out that the speedo has anything to do with it?

You sure? When I'm rolling like that I'm not looking at my own blinkers...

Yes, I'm sure. I always make certain traffic around me knows my intention especially when I'm moving at high speed. So yes, I do pay attention to my blinkers.

I know the fronts don't work beyond 65mph and I can't see my tail while I'm whippin' it. But neither left nor right signal indicators don't work either under same conditions.

Left arm straight out for left turn. bent at a 90 degree angle for right turn!

When I lived in Houston, signaling to change lanes was a nono. It just gave the other person a reason to cut you off.

I see, apparently I'm the first to have this problem because I'm not getting anything useful from the peanut gallery. Thanks for the jokes. But if any of the gurus can come up with a possible cause and/or resolution, please let me know soonest. Thanks.

Sounds like vibration might be the factor here Pup. I would suggest you inspect for wires with bare spots under the tank and under your rear fender, some have had the rear tire rub the wires raw and maybe put dielectric grease on your connections to include the EHC. Just sounds like the vibration at higher speeds might be wreaking havoc on your connections somewhere to me. I hope you find the issue, good luck...

 

[prizepup]

Thank you for the helpful suggestion, Brew. I've already checked those areas but will inspect them again. It's possibly a very small nick somewhere in the wiring that I missed the first time.

See if you have the problem at lower speed (lower gear) at the same RPM at 65 MPH.

If you do it could be a voltage regulator or its internal rectifier.

Kidding aside. I don't know if the Bulldog wiring is run the same as the Mastiff. Take a look again at the wiring under the rear fender. I think some have had issue with nicks that could cause shorts. Not sure about the fronts. May be on the same circuit.
