He has found a Napa brand flasher no ground strap that works and blinks proper speed. And also an adapter to reverse the one flasher.

I'll check these out. I'm just not sure if I have an issue elsewhere. One thing that makes me wonder is that my turn signal lights on the dash don't seem to be working. The gauge cluster circuit board is the all original. When I replaced all the dash lights with Leds I looked at the board and didn't see any issues. Had to replace a few sockets aswell.

Ok, this maybe some of the trouble.

Well it's all new from LMC. LEDs, fuse box, everything.

LMC has had a bunch of wiring issues with the relay kits for the head lights, there are many post on here about the wires being crossed up in the kits. I would be inspecting these parts good.
I would be looking at the half moon connector under the dash. I have had trouble before with them not matting up good and the pins coming out of the plastic holders when trying to connect them. All your turn signals and brake lights go through this connection. Just take your time. Check each wire with a test light and find where the juice stops.

Now that you mention that. I had to repin that particular connector with the original plastic to get that to work. Took me a while to figure out what was going on. I never used a test light on it though. Might look into that next.

Ah, I did not realize we needed two flashers - which is why my Hazards Flash Fast (Hyper Flash)! Though now looking at the fusebox, I see the flasher can at the top! Doh!

Thanks for this thread!
