how many volts out of gp relay

[trugertha]

i was wondering what kind of voltage i should get coming out of the gp relay?

[trampsdieseltruck]

i get 9.6 volts when the "wait to start light" comes on

[trugertha]

i get 11.5.. do you think i should replace the controller?

[trampsdieseltruck]

does the truck start ok.did you test the volts at the controller relay or at one of the wires going to the glow plugs.take one wire off of one of the glow plugs and hook up the (+) end of the volt meter and ground the (-) end.turn the key on and check the volts

[trugertha]

yes i did test at relay, ill test at wire in the morning..hopefully the new gp's fixed my problem and she'll go first thing, without plugging it in haha

[trampsdieseltruck]

when you installed the new glow plugs did you use anti-sieze in the threads

[Snotzalot]

Beru states antisieze isn't required.

[trugertha]

not required but never hurts haha

hmmm i had it working this morning 9v at gp connector then this after noon nohting no volts at the other side of the relay...but 12 on the hot side...i can hear it click when i push the button for my manual plugs, but no drop in voltage on my stock meter and no volts show up on my voltmeter either.. i assume relay ???

[trugertha]

fixed!!! thanx everyone

What was the fix?

[trugertha]

it was the relay, the controller is shot 2 but i just hooked up a manual switch, until i can afford a new controller, then ill set up a manual and the stock system
