Isolated dual batteries are a must in any Overland vehicle. The isolation part refers to how the batteries are connected and disconnected with the engine is running and when the engine is not. When the engine is running, we want the batteries to be connected in parallel positive to positive, negative to negative so we still get 12V, and the alternator can charge both batteries. When the engine is not running, we want to separate the batteries, so that if the House Battery is completely discharged, the Engine Battery remains unaffected and will still start the vehicle engine without issue.

Step 1: Follow the instructions that came with your dual battery tray to remove your existing battery and the large factory plastic tray, and install the new dual battery tray. Usually this involves cutting the factory plastic tray. If your tray mounts the batteries side-by-side or front-and-back, check how well the stock jeep wires for the positive and negative will reach each location. Whichever battery suits those wires the best can be your Engine Battery. Step 3: Connect the negative terminal of both batteries directly together. These will always be connected with large gauge wire, and never need to be disconnected. Step 4: Find a good spot to mount the solenoid. Check hood clearance, and make sure neither terminal will touch any part of the body nor hood. This will trigger the solenoid to turn on when the engine is running.
