I've searched the forums, but I've not found anything that is exactly my problem. The issue somewhere in my electrical system. Started out one day I went out to start my truck and it turned over very slow, but cranked. It started fine for the next week or so, and I didn't really think about it because I thought I had left my overhead light on. (I'm second guessing that now) Battery tests as good when it's charged and in the truck (700 cold amps) and the alternator tests good on the truck.

However, the battery will go dead in about two days after I charge it completely. It doesn't seem to matter how much I drive it or when I drive it. Example, it was weak about thirty minutes ago when I turned it over, but it cranked. After I drove it to the store and back (left it running) it wouldn't crank in my driveway.

However, I never get limp mode. I've had it where I knew the next time it was going to not start, I would turn the AC on full blast, the radio on, the headlights on, etc. and I couldn't get it to draw down or even fade the lights when it was idling.


Background-

This has just started happening, but in the last 1K miles I've done head gaskets, heater core, & brakes all the way around, and front passenger's side window motor and regulator. Since then the door lock actuator on the same door has gone out. I've noticed a high pitched whine in my stereo.

Any help is appreciated.

 

I'm just going to start posting on here so I can answer my own question in about five minutes. Just pulled the battery and looked back over things. Obviously a bad ground wire coming off the battery.
