Ok so i took apart the instrument cluster bezel recently to replace some lights, put it all back together and tested it all and everything worked after i plugged it in wright, the car ran fine when i started it, i had it running for about 10 minutes just giving the car a check over, it was running great. then it sat for maybe 2 weeks, and i checked some stuff on the radio and the glove box, i took the glove bow out and dummy me left it off over night and i guess drained the battery because the light. It's had a bad battery for a while now, but now the lights in the car won't come on when i open the doors unless it's on a charger. when i jump start it with the truck, it would run for a minute or too, then die, and again nuthing would light up, no dome lights, fuel pump, or anything. is it just a really fried battery? its had a bad battery for while then leaving the glove box open for 2 days, maybe it fried it. or could it be alternator or ignition problem?

Put in a different battery or get it tested and find out.

get a new battery, when the battery is drained that bad or if it has a bad cell it will only power the main functions needed to run the car. its like when your alternator goes bad things start to go off as yout battery starts to lose its charge, like interior lights, radio, ect.

can i test the battery with my multimeter? if so what do i set it to and what do i look for to see if its bad or good?

No, you need a load tester. A bad cell may have the correct voltage but not the correct amperage.

A load tester will test both.

When a battery is drained to the max, some cells will short out or not be able to recover (it damages teh battery). Just buy a new one and be done with it.

simple way to do it, take the battery out and take it to pep boys or advanced auto and they will test it for you for free
