GPR Test

[Goose350]

How would I test the gpr? Is it the same as the 7.3l or different?

a relay is a relay so if it is indeed a gpr just use a voltmeter to test it

[Goose350]

I figured that but what am I looking for? Number wise

6.0



7.3

voltage should be around the same as what the batts are reading ... not 100% on that but i would assume .. and thats usually around where mine reads when i test it

Ok. Thanks

its still a relay so to test just the relay u can hook a voltmeter to the output on the right nd see if i reads nething if it doesnt then check the one in the back (from the angle that the pic is at) and see if ur getting voltage there if ur getting volts on the small 1 nd not the big 1 then the relay is bad if ur gettin no volt on either then something is messed up w/ the ecm or wutever is sending the signal to the relay
