Here is my question, but I will start off explaining why I have this question first.
Because of the birth of my daughter my truck has been sittin a lot more then usual it was about a month an a half before I felt the need to start it up and warm it up. And on doing this the motor would barely crank over ( batteries very low ). So I took both out and charged them ( 2.5 amps for 3 days )to get a nice good charge in them, plus I had the time.
Question 1. is it normal for a diesel to drain batteries in that long of time sittin?
So then I put the batteries back in the truck but before I hooked them up I put a multi meter in line with positive terminal on passenger side and noticed a draw of
.208 amps ( seems awful high to me ) so I start pullin fuses the only fuse that would make a difference was fuse 15 ( Generic Electronic Module , Powertrain Control Module, Anti-lock Brake System, Brake Shift Interlock, Speed Control ) Once this fuse was pulled the amp draw went to .049 amps Im guessing this might be normal current draw through out the charging system.
Question 2. is it normal for the Modules on Fuse 15 to draw .159 amps on its own?
Question 3. is .208 amps too much current draw?
thanks in advance for the help
