thanks! I had to call in a bigger truck to help me.

The truck stood outside for a week. been kinda cold latelly. Started it this morning and was kinda hard to crank it over. drove to work, and then tonight at work, nada. hopefully enough just to charge the batteries.

thanks for your help.

I dont think it matters, which ever one is dead

[GoldieStroker944]

most of the time when its really cold i will end up having to hook to both at some point or both and the same time (two trucks)

It should not matter but usually it takes a long time to jump one unless you have more than on set of cables hooked to it like the last post says.

do I have to be conserned about the FCIM or anything due to the battery dieing on me?

Your primary battery is the Passenger side (the one the GPCM and starter/Alt is directly connected to)...the Drivers side is considered the Aux battery, true they're connectred in parallel, but I would opt for the Pass side first...it is usually the first one to go ^^ up also. Yes, I would be concerned about dead batteries. When my wife left my headlights on all day (she still denies this)...of course my Passenger side battery would not hold a charge. Replaced both batteries...1 month later replaced FICM. This is a common occurrance. I would definately check your FICM as described by Dr Quad. You may even consider getting a FrankenFICM...there are a few guys doing this Swamps, IDP, etc..

Moyock is 100 percent correct. If your doing a jump hook to the passenger side battery that is directly connected to the starter and alternator. The Driver is mainly AUX.
