View Full Version : Perko switch install
03-25-2008, 12:06 PM
I have a 99' Maristar and I am going to install a second battery, Cope wanted $250 to install it. I have a couple of questions, it seems that where the battery is now is a little tight. Does everyone install them there? (under the rear seat on the port side) and where do you install the actual switch? thanks in advance

I have mine under the seat in a '91 PS 190. I put my switch under the engine cover, so the wires to the starter were short. Don't know if that is really necessary though. Keeps the switch dry, and out of the way though. Do a search for "Dual battery" on here, there is lots of info about them, and how to do them.

I have a 2005 Maristar, not sure how that compares to the 1999, but both batteries are under the seat together, and I mounted the Blue Sea Switch on the divider between the storage area and the engine. I didn't put it on the removable door, but the the triangle shaped piece closest to the seat back. The wall is that high density plastic stuff that will hold it nicely. Cost should be the battery $90, switch $35, and cables and connectors $20. So you are looking at around $150.
I used the Blue Sea Switch over the Perko because of the binding posts were larger to attach the power led from the stereo amps.

Read through this, another way to do it.

I added a second battery in my Maristar last year when I bought the boat and used a perko switch at first. Then I found Deisel's posts in the dual battery thread and converted it this winter to the automatic relay! IMO, I'd go with the relay, much simpler and no need to remember to move the switch!
Here is the link.
