Loseing charge over night.........

[spoolinawdtsi]

I have two red top optima batteries. they have been tested good. New alternator.
When the car sits overnight it kills the batteries an will not start without being jumped. once jumped an drove the car will start fine all day long.
\\Just wondering what would draw that much juice from the batteries over night? is there any common simple fixes?

When my step dad had my truck he had kind of the same problem, mines a 96 F-250, he took a look at a lot of things, it ended up being the light in the glove box compartment. It took a couple days instead of overnight but try looking at the lights inside your truck also

Test the amp draw at key off with an ammeter.....i had a 4 amp draw that took me forever to diag. Should be little draw when off. If you have a draw, pull each fuse and use a multimeter to check for any draw on each circuit.

THIS HAS BEEN BOUT A 3 WEEK process. As of now i just pull the cables each night.
I did take it to autozone an they brought out the little machine tat checks the volts an amperage while runnin an then shut off. with key off it had very little draw an he said it was in the normal range.
