How would i jump someone off with my truck? it is a 2004 chevy silverado 3500 (6.6L diesel)?

chevy diesel
Cody asked:


I’m asking because it has 2 batteries, im pretty sure the voltage is still 12volts. How are they wired and would i just connect cables to one battery? could soemone jump my truck with a car that just has one battery?

Thanks

  1. Connect to the primary battery which is isolated from the auxiliary power battery:

  2. considering the amount of OBCs on your modern vehicle,many of the manufacturers do not recommend jumping or being jumped by another vehicle.if you want,you can get one of those portable rechargeable battery packs from the auto parts store.

  3. Yes, you are correct as far as your vehicle still having a 12 volt system, as they are hooked up in a parallel circuit. If they were hooked up in a series circuit, that would make for 24 volts. It is best to hook up to your primary battery, not in that the other one is isolated, because it’s not, but because it’s the one that is most directly connected to the Alternator.

    Otherwise, follow the proper procedures as outlined in the link the first poster provided, especially the parts about having both vehicles off, and making the last connection away from the battery. The Master Brake Cylinder often works well for this, if you can reach it. Also that the other car has it’s doors closed, and/or as much else turned off as possible.

    As far as someone else jumping your truck, yes, that can be done. It would be helpful if the other car had a battery with a high CCA/Reserve Capacity, and a High Output Alternator, as your diesel-equipped vehicle requires more power to start it, hence the use of 2 batteries.

  4. You have 12V system. As Catman said, you have 2 batteries to double your cranking ampacity, because diesels have a higher compression ratio and are harder to start (and also a larger reserve for energizing glow plugs/grid heater).

    You don’t have a primary battery, each battery is equal (because one is NOT isolated). You just pick which ever battery is closer to the vehicle ot be jumped so that you don’t have to stretch your jumper cables as far and chance them coming loose.

    Just remember, pos to pos, neg then your last hookup should be the dead car neg to a ground spot on the car. The alt housing or bracket is one good spot, somewhere on the engine block. As Catman said, have the dead car doors closed and everything turned off, this is to reduce the load on the electrical system when you connect the jumper cables to reduce the size of the spark that the cable draws when first connected.
