What is the correct way to re-install new batteries... Ours were stolen last night so we don't have a reference to go by.

1. Buy New Batteries
2. Put them in the battery tray
3. Secure them
4. Connect postive terminal to red cable, connective negative terminal to black cable.
5. Start Truck.

the Isuzu npr diesel truck uses a 24 volt system. Connect the 2 batteries in series, i.e. Connect positive post to negative post between the 2 batteries, then connect the negative engine cable to the other negative connection on one battery and the positive engine cable to the other positive connection on the other battery

My 1993 W5 had batteries stolen. what is proper technique to connected dual
batteries? Am I understanding the batteries are plus to minus? I belive the closest batter to the exterior of the truck had the positive terminal towards the rear of the truck. Does this sequence matter? The rear side goes directly to the frame. Is this a positive ground?
Truck also has lift gate, and looks like cab side has connections which go to starter etc.

Please HELP>

My 1995 diesel has a 12v system with two batteries. Batteries are connected in parallel so both negative bat terminals run neg to neg via short cables then connect to ground (black cable) and both positive terminals run pos to pos via short cables then connect to power (red cable).

The 2007 is a 12 volt dual battery POSITIVE GROUND SYSTEM, which means you hook the negatives of both batteries together, and both positives together. and the POSITIVE CABLE HOOKS TO THE CHASSIS FRAME, and the NEGATIVE FEEDS THE INSIDE OF TRUCK, TOTALLY BACKWARD FROM MOST MOST CARS AND PICKUP TRUCKS
