Actually, regarding the ammeter, I was exploring the possibility that the ammeter was old, had some kind of internal short, had been permanently installed, and that the current drain actually began shortly after the installation but the OP had forgotten it. Evidently that isn't the case.

well, i changed another solenoid. turned out to be the starter solenoid. I thought the starter solenoid was on the starter but i was wrong. haveing a hard time getting to the glow plugs. lack of knowledge. have to do a bit more research to find out where the glow plug relay is.

You can use your ammeter on circuits to test whether or not that circuit is the culprit. No use in changing out parts randomly. You can buy a clamp-on DC ammeter at Sears for not too much. It just goes around the wire like a set of pliers and you get a current reading.

Well, i made a breakthrough today. My battery drain stopped when i disconnected the 2 red striped high voltage wiring harnesses going into the engine. They both have to be disconnected to stop the battery drain. So that means either glowplugs or injectors. Probably glow plugs. But if they are not turning off then it must be a controller. Maybe the temperature sensor?

I went to float the Guadalupe this weekend, left my truck at a friends house, and found the truck with just enough voltage to start.
What I've changed:
-Starter and Starter Solenoid all in one go
-IDM relay and 60amp fuse
-Fuel Pump Relay
Mike, have you had an issue or know of an issue where the GPR would cause this kind of drain?

I changed the glow plug relay. Didn't do it. I'm thinking now that its the glow plugs. I'm just not sure how a glow plug failure could cause a 60 to 70 amp power drain. Someone suggested a partly failed glow plug drawing lots of power.

I hope one of us can figure this out sooner or later...
I'm going to borrow a multimeter from one of guys from work tomorrow, start pulling from the distribution box, and see if I can figure this out...
