i have a 95 gst that is literally draining every battery i put in it. i thought it was the battery, so i bought a brand new one, still did it. so then i thought it was the alternator, bought a brand new one, still did it... looked for loose wires, nothing. changed cables, nothing. i even put another new battery in it, drove it for like 15 mins, parked it and the nxt morning it was completly dead!!!! please help, im at my wits ends!!

 

Your gonna need a DVOM (digital volt ohms meter) Hook it up and see how much amperage its drawing and then pull fuses and see if the draw goes away.

 

x2. it sounds like a cable issue to me. also i would get the charging system tested, autozone and advanced does it for free.

 

do you have an aftermarket audio system in the car? Something is running on constant power.
