LED & relay swap...now issues (1 Viewer)

[cstraface]

Ok, need some help. I’m stumped. 1/74 production. Swapped all turn signals, markers, and taillights to LEDs. Swapped flasher relay with a Coolerman unit.

Both dash turn signals are now coming on with the brake light switch. Brake lights work. Turn signals work on their own. But if I press the brake pedal, my left and right signals light up on the dash. I tried swapping the brake lights back to the old bulbs. Same issue. So must be the turn signals?

Can anyone offer any advice? Open to any and all suggestions...

The new flasher relay provides the correct resistance for the LED turn signals, but not for the brake and tail lights. You'll need ballast resistors for those.
