Re: PIAA Problems
The lights are directly wired to the battery with a fuse in the plus side, near the battery. Out of sight is the normally open relay in the direct circuit to the lights.
The plus line to the switch also is fused. The black wire at the switch is for the LED. With voltage going to the switch the LED should be green. When you push the switch the LED should go red and the circuit to the relay will be completed, closing the relay.
Unfortunately, I do not remember where the voltage to close the relay comes from. I'm guessing it is from the voltage to the LED? I seem to remember that the ground for the relay is tied into the PIAA's wire running directly to the battery's negative terminal?
I'm also guessing that the slight drop in voltage between just powering the LED and power to the relay and LED causes the LED to change color to red?
If the LED burns out, the switch and relay still work.
