Hi all, i have an 03' Pontiac vibe AWD 1ZZ and it just recently began to turn off and to kill the battery. I thought it was the alternator, so I replaced it. I can jump start it, but it dies after 15-20 mins and it kills the battery completely. The only electrical work I've done to it is to replace a few blown bulbs w/ LEDs, replaced door speakers and now the alternator. I am mechanically inclined, but not a hardcore mechanic.
Thank you and any advice would be greatly appreciated.
