Pull the master switch in the door.
Turn on key till dash lights come on or just start it.
Check the plug for 12V on pin 1 the blue wire and check for a good ground on pin 5 the White with black stripe.
Turn off key.
If no power with good ground pull the main power relay.
Turn on key and and check for 12V on pin 2 and pin 1. They should both have 12V. Pin 1 energizes the main relay when you turn on the key and start the car and stays powered till you shut off the car.Pin 2 is power from the 30A CB that feeds the switch when the relay is energized. If no power on 2 then change the CB or try and reset it. The CB either heats up and trips when too much current and resets itself when it cools down or you have to manually reset it. I havn't looked at it so I don't know which it is.
Try those steps and let us know how it goes. |
ok , tried those steps today and still no luck
pull the main switch off the door,
with a good ground i tested the blue wire nothing
i tested the white with black wire nothing
so i went to the main power relay
with good ground i tested all pins
and i got a power on the number two pin, and none on the other 3
so with the main power relay off, i went to the 30A Power CB
i got power on the pin 1 and none on 2
what does this mean? and how do u reset the CB
