Dead Battery 6.4

[Devildog1]

Hey Guys,

How do you jump start a 6.4? Which Battery?

Thanks

I've seen guys do it either way, personally I would jump to the main battery (I forget which side its on, drivers I think) its the one with the cables that go directly to the starter. Then when you can take your batteries out and charge them on the lowest amp setting you schedule will allow. That is assuming your wanting to keep them for a while.

There isn't a "main" battery: they're wired in parallel. You can have your truck jump started off of either one.


Semper Fi.

Well I figure why have the juice go from one battery over to the other battery then down to the the started. I call the battery that goes straight to the starter the "Main Battery" And ya with them being parallel it really doesn't matter.

Hot on dead batt's hot lug.
Negative on dead truck's GROUND, not lug. Just jump it like any vehicle.

High compression. A single battery does not have enough power to compress all that air, so you need more power.
