Hi,
I recently rebuilt the throttle body on my 87 R10. It was my grandfather's truck that my grandmother sold me a few years after he died. After rebuilding the throttle body it ran and drove great. Battery was dead when I first bought the truck (it had been sitting for a year and a half). Battery was replaced, I tested for a parasitic load, and the it was only pulling about 16mA when turned off. I left the battery hooked up over night after the throttle body rebuild and the next morning nothing worked but the dome lights. Tried jumping the truck off and nothing happened. Battery was reading about 12.55 V on my meter, so pretty close to a full charge. Went and got it charged anyways and tried it again yesterday, upon trying to start the truck, the radio and all electronics blinked to life, but before it could turn over it all died again and my battery (which was at 12.7V after charging) dropped immediately to 12.66V. Battery seems good to me every time I measure it, and it seems like a short to ground somewhere. The weird thing is that there are no blown fuses. Anyone have any ideas on where to start trouble shooting? Or any good literature for schematics? Pic for attention.
