How to wire in a second battery?

Asked by Joe Jul 05, 2020 at 06:57 PM about the 2019 Chevrolet Express Cargo 2500 RWD

Question type: Maintenance & Repair

Can I come off the main supply at the fusebox under the seat and ground to the
body, or do I need to run positive and negative wires from the main start
battery?
The second battery will be located behind the driver seat.

2 Answers

Run the wires positive to positive and negative to negative. Use a battery isolator unless you want the second battery for starting. https://www.etrailer.com/question-259273.html

Run the wires positive to positive and negative to negative. Use a battery isolator unless you want the second battery for starting. I would wire it directly to the charging system and other battery. https://www.etrailer.com/question-259273.html
