If you lost power while driving and it did not start again, it could be an alternator issue. Double check the battery just to make certain it isn't an issue with the cable connectors too.
If it lost all power it could be the battery connection.
It could be your connection to your battery. If its bumped loose, you would lose all power, even while driving.
Dead cell in the battery or something is on pulling power from the battery. If it is a dead cell the battery must be replaced.
no because power steering is a hydrollic assist system
you could have a bad ground wire that was my problem
Could be the switch between the front seats, or a fuse, or a shortcircuit in the wire with power from the battery.
Yes, a dead cell in the battery or something is on drawing power from the battery.
Clean them and see.
Either the battery is defective and has a dead cell or something is on which is pulling power from the battery every night.
One possiblity could be that the charging system has failed and you were running off battery power only, eventually the battery goes dead and so does the car.
The old battery was bad it could cause a power surge and plow the main fuse.
