thanx brb

Expert:  Peter Bagley replied 1 year ago.

has anything been added or worked on recently or did this just happen all of a sudden? It sure sounds like a short you may have to treat this as a short or draw and start pulling fuses to find which sircuit is effected unless you have a short detector.

tbh its the 3rd time. mom drives it and she says it'd turn on, but today it didnt
Customer: replied 1 year ago.
nothing has been done to the car though we bought it 4-6 months ago an it was fine
Customer: replied 1 year ago.
ive pulled fuses and nothing seems shorted out. i do notice the positive batt terminal is warm to the touch after trying to start it
Expert:  Peter Bagley replied 1 year ago.

I can't seem to find a wiring diagram for this so I'll opt out so another expert may help you further , good luck.
