Message: [QUOTE="psduser1, post: 1550286, member: 735"] I'm checking voltage across my gpr, and its not right. Power in is 12.8 ish on the main lug-battery voltage. Turn the key on, the wts light is lit, and voltage on the scanguage drops to 11.8 ish, for about 2 minutes, just as it should. Trouble is, with the key on, at the relay, I have 12v on both small posts, and 0.00 on the terminal to the glow plugs. I've tried with a two year old stancor, and a new parts store relay, so I don't think its a faulty relay. I've checked the harness to the junction between the heads, and all the wiring looks good. A quick look at the rest of the wiring to the 42 pin connector looks good, as well, short of opening up the whole loom. What am I missing? [/QUOTE]
