My 2002 suburban battery keeps draining. My battery gauge reads good so I thought it was the altornater and changed it. It started up after charging the battery and did so for half a day. I got in this morning and it was nearly dead again with not enough juice to start up. I feel stupid for assuming it was the alt. But now can't figure out what's pulling the energy. Is there common issues with this year suburban? Can anyone help?

get the battery tested

This is why we TEST parts first instead of just throwing parts at an issue.

You need to identify the source of the drain. You can do this if you have a multi-meter. Keep pulling fuses until you see the drain drop. At that point you've identified the circuit where the drain is.

Sorry took so long to get back to whomever cares. I did use a multi meter as suggested and found I had a draw coming from the tow adapter plug I had just bought from uhaul. It was actually a surprisingly high draw, as well as the radio. I pulled both fuses and my truck has started ever since

Ronald - ALWAYS suspect something that was changed/fixed/added recently. You didn't supply this bit of information about something "just bought" or several here would've jumped all over it.

Agreed
