Battery Drain on 2000 Suburban

Recommended Posts

We have a 2000 Suburban 1500 4x4 that my wife inherited from her mother. We've been fixing all the little things here and there, but we're having an issue with the battery draining. If it sits for more than a day the battery goes dead. We've replaced the battery a couple of times in the last 2-3 years. I've used a multimeter and pulled fuses one at a time, but don't see a constant draw. I've disconnected the VCR and power inverter. It has an aftermarket radio, and I've pulled that fuse. Still no luck. One strange thing I've noticed is that it won't run with the battery charger connected. It will start, but dies as soon as I release the key. As soon as I disconnect the charger after charging it, it starts fine. I'm stumped. Is it possible there is an issue with the alternator and/or voltage regulator? Is there something else I may have missed?

I'd pull the alternator and have it tested.
