What would cause the electrical system to quit totally after it has been working perfect.
What is your question?
The problem we've had is the electrical system goes crazy with door locks going up and down, lights flashing, radio changes stations and from Sirius to FM on its own, engine tries to stall and bucks. Once we get it running it will run perfect then after driving a ways we shut it off and everything is totally dead.
What makes this problem better or worse?
Installed new battery twice, shorted battery once.
