Chevy express van dual battery setup. Each car battery for chevy express offers a 2 year nationwide free replacement warranty 3 year warranty on duralast gold and platinum batteries. Its almost identical to a group 3478 or group 78 battery. When you order a 2500 with dual batteries you receive 2 48 series batteries which includes an isolator. You can set up a simple system in a few hours with a few basic tools and the right equipment. I ordered the gm factory cables for a dual battery install and will have my installation shop add the appropriate isolator and fuses. The factory ac delco group 48 battery is unique to gm trucks and its rated at 615 cca cold cranking amps with 110 rc reserve capacity.
I am trying to connect a battery isolator dual battery setup in my 2009 express van. So i finally go over my secondary battery. I am following the installation instruction per the isolator. One wire from the alternator that used to go to the primary battery now goes to the middle of the isolator. I forgot to mention that i am actually able to start of both batteries as well. Duralast batteries offer best in class vent caps a solidium weld system robust separators lifespan negative paste and power designed to meet or exceed your specific vehicles needs.
You need to run power from the fuse holder bus bar side to the top post of the isolator and then run power from the bottom post of the isolator to the second battery. I had a lot of help with this install and couldnt have done it alone. The tp2 configuration is the same as the tp3. Prior to the introduction of the tp3 770 cca dual battery setup the tp2 option was the most powerful dual battery option for the chevrolet express van. So we chose an odyssey 78 pc1500 a agm battery as the auxiliary which delivers 880 cca and 135 minutes rc. The battery is then grounded to the driver side head via a m10x15 bolt.
At this point is when i would run the power and grounds for the second battery. While setting up a dual battery system may sound like a big task its actually not that difficult. There are 4 terminals.
