Ah, I re-read this. I can look at the pins for corrosion but resistance testing is over my head. I'll pass this tip on to my mechanic.

Maybe the pictorial will help you some.

I love the smell of diesel smoke in my hair

Hey I COULD do that; and a co-worker has the resistance tool I think. Excellent directions with photographs.

Again. BIG thank you gentlemen!

Checked for corrosion, no problems with connectors or sockets on relay or on the connecting plug between the wires.

Well the car started acting flaky electrically after a 3 hour ride. The last few minutes the radio died etc... One thing I have been noticing is that it has been sounding like the battery has been taking a beating after driving it, even on short trips, as it would turn over slowly (even though the battery is almost new and the car has a 2-3 year old new alternator in it).

Went to start it today and it barely turned over. Ironically the glow plug light did come on.

Could a bad relay be shorting out the system causing a power drain or is this indicative of another problem?

If I am unable to test the relay, I am very tempted simply to buy a new one and gamble the money. Tired of the problem....

Thanks again,
Matt

This may not make a bit of difference in your case but check all of your grounds. Find out where your engine grounds to the chasis and make sure its intact and corrosion free. I had a really odd electrical issue where my gauges where jumpy then all of a sudden it wouldnt' start. I pulled my instrument cluster and repacled it and had the same problem. I noticed every light in the cluster would turn on when the cluster touched the speedo cable. I was getting a steady 2.97 volts from the cable??? I also got random voltages from engine parts that definately shouldn't have had power. Thanks to Craig for telling me to check my engine grounds. I was in a hurry because I'm out of town on vacation right now so I took a jumper cable, attached one end to the EGR and the other end to the negative post of the battery and it started! Unfortunately I had to leave right after that so when I get back I'm going to find my main engine-chasis ground and clean it. It may not help but its worth a shot.
