Electronic led signals

[Niagara Dave]

Just want to share a problem I came across. My signals would not work properly when the engine was running. I traced it to the coil wire. When I wired the engine compartment I tried to make the engine harness look neat and I combined the MSD wiring with the main harness. The coil wire was inducing electricity and interfering with the electronic flasher causing the signals not to work properly.

Good catch. You can sometimes eliminate the induction issue by twisting the pair of wires. In aviation it is common to use twisted pair & shielded wires to resist interference by electrical noise. Aircraft Spruce is a good source for twisted pair shielded wire if you want to try it on your coil wires & re-run them in a common loom.
