I don't know whats causing it but my battery is always dead in my TA! There is a new battery in there....and it's not my alternator. Other then exhaust and line lock, my car is stock. It even have the stock radio. Line lock fuse is out, I thought that was it...but its not. I charged it on Friday...drove it for awhile....drove it for awhile on Sat... and went to start it Wed morning...and it wouldnt even crank. Anyone have any suggestions? It's driving me nuts!! I charged it yesterday and drove it for awhile...even managed to take it to school...I am going to try and start it in the AM to see what happens.
There is 100% NOTHING left on. I don't even set the alarm on it. I am very open for suggestions on what it might be.
Thanks!
