LED Taillight Swap

I removed the Dave Irwin LED taillights from 721, planning to install in the "new" Z. Brought along the LED flasher that worked in 721, too. Guess what? They no workie! The "new" Z is a 10/70 '71. Any thoughts or comments, 'cause I'm stumped?

Could you have reversed polarity somewhere? LEDs don't like reversed polarity.

I tried both sides of the flasher. Got a buzzer going off with one configuration, nothing with the other. The hazards cause one LED taillight to fully blink, while the other only lights up about a third.

Was everything on the "new" car functioning before you attempted the swap? I've found that a bad hazard switch, or one that is not in the correct position can wreak havoc on the turn signal system.

Everything worked before I plugged in the LED taillights and flasher and everything works after I changed back. Guess I'll wait 'til Dave gets back from MSA to ask more. Thanks for the thoughts.

Go back to the basics. First, verify that you get voltage to the tail-light connectors. If you have voltage at the connectors, then just run 12V from the battery to the tail-lights to see what's working and what's not.
