Question about Cars & Trucks
Battery failure and new alternator runs down so something is darning the battery.,
I recently had the same complaint and after alot of trouble shooting I located my problem to be a wirring harnes conector on top of the engine for the injector pump moduel. The contacts looked real good however the theory is when they heat up they warp away from their mate and this activates the computor and keeps it from going into sleep mode thus draining the batteries. You could have any conector problem but I would look where the temperature changes the most. In my case I cut the conector out and soldered the wires together. My batteries seam much better now it has been 2.5 months which is a record for my batteries going dead.

Possible loose or worn alternator belt. Check the condition of the belt. If it's worn, replace it. If it's just loose, tighten it up.

has anyone thought about the regulator, i think that its built into the alt, replace it and then see if the prob continues, you can get a pass on the alt test and still have a bunk regulator

What is the temperature gauge doing?
Does it get to about half way, or does it barely get off cold?
If it stays fairly cold, then it is probably the thermostat jammed open and needs replacing.
The glow rail controller senses engine temperature to turn off the glow rail (about 50C).
If the glow rail stays on + short trips + winter driving with lights, defrost, heater on, lower air temperature, then the alternator cannot keep up with the glow rail staying on.
