Check things like the under hood light and be sure it goes off, and glove box light, Alternator can have a bad diode and drain the battery down, These are things to check.

i own a repair shop,,and it sounds like the alternator is draining the battery dry on it,,they will do this if the regulator goes out on them,,as long as you drive it its OK right,,but if you let it set they go dead,,this is typical of the alternator when it goes bad,,you can take it somewhere and have it checked while its on the truck,and they can tell you for sure,,id also check all my ground wires on it,,it may not be letting the alternator charge the batteries good enough,,good luck with it,i hope this help,s.

There is an easy test for alternators (at least it's used on gasolene engines). It should work. With your car running, take a flathead screwdriver and hold the end of it sideways to the middle of the spinning pulley of the alternator. If your alternator is good, the screwdriver will be sucked in SORTA SLIGHTLY by the electricity/ magnetism. If your alternator is bad, the screwdriver will bounce around (SORTA SLIGHTLY) on the spinning pulley. Put the end of the screwdriver to the middle of the pulley like this > ------o and see if it stays put or not.

It sounds like you have something stuck on, such as a dome light or something. If you can't find anything, start by taking your batteries down to one of the autoparts chains and have your batteries tested, usually free. If they're good, ask them if the can bench-test your alternator, usually free, also.

The regulator. Also look for a dead short.
Most parts stores will check your charging system for free.

replace the batteries every 3 years as the maintenance manual states

You either have an electrical short or you need an alternator.
