positive battery to glow plug side of the relay

about 30 seconds should do it...

 

[97powerstroker]

what do you mean 30 sec should do it,i shouldnt start the truck with it jumped?

 

[97powerstroker]

so do i just hook pos to neg up to batt,then hook them to the big terminals on the gpr,

Check with a 12v test light there should be power on one of the large terminals on the GPR and you can just jump it with a small wire over to the other side

 

[JLDickmon]

no, just use your jumper cable like a big jumper wire...
just jump it and power the glow plugs...
let it cook for about 30seconds,
I'd disconnect it and lay the cable aside so it doesn't get all entangled in the belt..
try to make go

how can i do it with jumper cables

 

[Wingdog]

With just the positive cable to the GPR. The GPR should be grounded already so don't put a negative cable on it. There is constant power to one of large top posts on the GPR at all times and when you turn on your key it sends a signal to the GPR wich makes the power jump threw to the other large post and then to your glow plugs.

alright thanks guys,gnite

Good luck, if that doesn't work you may be in for a new set of glow plugs.
