How to wire a 2nd battery

[dogrocco]

I want to add a 2nd battery that will run the stereo. Does anybody know what i need? I was told I need a isolator. I am just not sure of the parts I will need and what type of battery.

You need a battery switch, some 0-gauge marine rated cable, and the mounting hardware for another battery. I highly recommend that you have your Tigé dealer do it. They can get you the exact same setup as the factory would have, and probably cheaper.

You can do it yourself, but as Ruune says, you don't need an isolator...a battery switch will suffice.

The set-up is pretty simple:

• Ground cable between both batteries (preferrably the same guage as your current ground cable)
• 2 cables to connect from each positive battery terminal to the battery switch
• Battery switch
• Battery Box

You'll want to put anything you want to be able to have run from either battery on the battery switch.

I put my own in and it wasn't a big deal. On my boat, I had to relocate the TAPS hydraulic pump, but again, no big deal. Be sure to measure the exact length of the 3 cables you'll need. My dealer made the cables for me because they didn't have time to do the install in the timeframe I needed.

I did this write-up a while back for adding a 2nd Deep Cycle to my boat. Just ignore the 3rd battery in the diagram.

Let us know if you need anything else
