[QUOTE="mikeeg02, post: 1399531, member: 24194"] Well I wouldn't keep that part as useful information and carry on with your investigation. What is the voltage across the two larger terminals on the GPR solenoid? With the red probe on the one large terminal (B+ into the GPR) with the ground probe on the other large terminal on the solenoid (Wire that goes to the glow plugs) Polarity in this case with a DMM doesnt actually matter, just so you are going across the two large terminals with the DMM, and having someone turn the key on. I know you said you replaced the GPR, but if the higher the voltage, the less power is getting into the glow plugs, and more is being "eaten up" (due to poor contacts) IN the GPR. [/QUOTE]
