Now this has happened twice. My truck sits up for a couple of days and the batteries are dead. I put the battery charger on them and they charge up and are ok for an few months.
I bought the truck in April of 07 and it has 14500 miles.
No switches or key left on.
Any ideas

 

Sounds like something is discharging your batteries. if nothing is left on let the dealer figure it out.

 

Are you leaving the sentry key in or close to your truck? There were some posts about this last year when the 06's were shipping with sentry keys. Do a search and you may find your answer.

 

staarma the key stays in all the time...

 

my friend had the same problem with his '06, dealer replaced alternator under warranty.... no more problems

 

Try taking the keys with you. It seemed like the threads were relating the fact that the sentry key was being left in or near the truck and that was the draw. I can't remember for sure though.
