I get a voltage drain on my truck. it will go down to 11.4 volts in 3 days .I cheaked for draw and am pulling 21 millamps. dealer said this is normal and I should drive it more often like every other day or more I still think they are not telling me the wright story. is this normal or do I need new batterys truck has 4110mi. and it didnt do this before.maybe someone has had this problem also .thanks

 

If you are correct and not measuring voltage draw while the grid heaters are on to me that means that if you don't drive truck every other day it won't have enough voltage to start by the third day or so. There should be a small draw for various electronics on the truck but I would expect it to be able to sit for 1-2 months without having the 2 batteries drawn down so much that the truck will not start. Find another dealer would be my suggestion, sounds like something is deffinatly wrong.

 

I've read some posts that the 06 will drain if you leave the key in it.

I think there is a TSB for charging enhancement but don't know if to applies to your truck, it's the same number has the hard start TSB.

how long was it sitting for???


fill out your sig please

 

Easily within specfications. With that small load it should take weeks to draw down the batteries.

I suggest the batteries need to be checked.

 

had mine in the dealer for the same thing last week. they did a TSB for charging enhancments. Have not let the truck sit since then but I plan on letting it sit for a couple days next week to see if it worked. My truck would be stone dead if I let it sit for as little as 3 days..........

sad part is i had to jump it with an old mitsubishi pickup that been sitting in my driveway for a year untagged..........but still freakin starts!

 

Same here: no lights on or no key in shut down 12.7 v 12:30 pm ,12.4v 4:00 pm,12.3v 7:00pm,12.2v 9:00pm, 10/12/06 11.8v 8:00 am I still think it is the batterys

 

How are you able to check that, are you placing a charger on one of the batteries and reading it? I want to know because I better check mine to see if it is draining.

 

I have let mine sit for over a week and it fires right up. Something doesn't sound right here.
