2002 Excursion with 7.3. Hey truck just died on my wife and i towed it home. the batteries are 2 months old and all the terminals and grounds are perfect. batteries test great but the truck just died. there is no power whatsoever. no lights no doorlocks, nothing at all. is there any kind of main fuse or solenoid that would cause this type of problem. i need this thing running quick.

Don't know if the Excursions suffer from this, but in a '02 Pick Up this can do that -> POTENTIAL ELECTRICAL CORROSION if your truck is like mine......

That was right on the money. I found the problem about 2am and fixed it the next day. Thanks alot for the help.
