loose all battery power

Hi everyone. my truck is out of commission. needs new tranny, and has been sitting for a few months with ocasionly starting it and let it run. so its about 15 degrees here and i believe i have a short in my glow plug wires somewhere(darn mice!) i turn the key to on and volt meter drops instantly and lose radio and what not then about 10 to 15 seconds later it stops and the battery charger brings my electronics back. just wanted to confirm if it is was i think it is. thanks Chris

You might have weak or dead batteries. Especially if it's been sitting in the cold.

How long was the charger been doing it's magic? Completely dead batteries may not come back from the dead depending on the age and condition. These trucks need an awful lot of juice to power the GP's and fire the injectors.

Make sure the charger is hooked up properly. I have seen those symptoms when a charger has been hooked up with the cables reversed.

I would agree with this. It sounds like your glow plugs are working properly. When the key is first turned on, the voltage required to run the GPR & glow plugs kills the rest of the electonics. When the glow plugs cycle off, everything else starts working again.

If you amprobe the glow plug wiring at the relay you will be suprised at how much current it draws. I did mine and it peaked at 119 A.
