my selenoid to cut off feul is not lifting up to help turn the feul supply on.
i have read about checking the wiring harness but am a bit new to electronics diognostics.
i have a volt meter....how do i check the relay?continuity,amperage?do i ground out and look for that from the relay or harness?right off the selenoid or relay?

thanks

 

Wellllll, mine went bad. it actuallly wouldnt shut off when thekey was turned off. Went to my local Cummins shop, they metered it while i watched. they gave me a chice, new Cummins part,or an aftermarket one.its spendy, but the Cummins one is much more stout>

 

Good place to find a new one or you could make a fuel shut off pull cable.

A good discussion here that may help you

If you want to ghetto check it, you can put constant 12 volts to the red wire then just touch the white one. The red is "hold" that holds the solenoid open, white is "pop". Just make sure you don't put constant power to the white wire or you'll fry it. White pulls a lot of amperage to pop it open, red pulls just enough to hold it open.

 

thanks for the info
i am going to look into doing a manual on/off cable
anybody got any links to that?
