Battery Drain 1995 Z71 4wd
Two months ago my 95 silverado was completely dead after setting for 5 days. Changed battery and all was well until yesterday when again it was dead after setting for 5 days. Not sure how long it actually has to set to go dead this just happens to be the time frame. This is so intermittent i have no idea how to find culprit. Is there any one item that would be more suspect than another, can a dvd player somehow stay energized and drain a battery with the ignition off. Other than lighting system and remote door locks what else remains under power with the switch off. Am thinking about installing a priority start battery isolater, but would much rather find the problem. I did notice that turning the ignition switch to on would make the function lights of the light switch illuminate but this is probably normal. Truck has approximately 60,000 actual miles and is in excellent shape. Any help appreciated. tia. pahoo31

I would check all the grounds and if you know it will sit for a few days before you let it sit take a minute and go through everything the dvd player lights radio etc and make sure nothing is on and see what happens.

Check your terminals. Sounds simple and something you wouldn't think of. My truck was slow starting and the battery wasn't charging and only running at 12 amps. My truck was completely dead one day and I went to jump it and noticed the terminal was loose and never had a problem after. If the terminals are loose or have build up the alternator can't charge the battery the same while driving which could be why its dead when you go to start it again. There's also 4 grooves that are on them. You'll notice them when you look. Rotate it until you feel them lock in and you'll get your best connection. Also the threads on the screw could be worn out and not locking in right. There only a couple bucks and wouldn't hurt to just buy new ones and see if it fixes it

Thanks for your reply. Terminals were fine. Now looking for relay locations. Would anyone know where the following electrical relays can be found on a 1995 k1500 silverado 4 wheel drive pickup.
Fuel pump relay, heater control high fan blower relay, abs relay, instrument light panel relay, and headlight relay.
Read elswhere that these are the most likely to cause parasitoc issues.

Thats the problem, intermitent. I checked it with a multimeter and when all is well the draw is 10 miiliamps. Is there any way an alternater could cause an intermitent drain, like stopping in a certain spot. This never happened until i put on a new alternater, but i have been told that if it was defective it would be defective all the time, not intermitent.

If the battery is "drained" overnight or over time it is something drawing current when not running.

Notorious battery drain ( intermittent) and was a factory recall was the cooler weather would cause the door panel to allow the door jam to open slightly and cause the dome light to come on. Turn on the dome override switch.
