Every boat should have on

I really belive everyone should have one of these on their boat. This is priced well below other battery isolation products and is a quality product. The instructions are probably not specific enough for someone with no knowledge of circuits to understand as they are somewhat generic.

Pictured on the photo is how I mounted the batter switch, I couldn't find a picture of one flush mounted on the net, I was really pleased with how this came out versus miunting it on the surface.

A tip that I used: The instructions tell you to run the postive (B) cable from the Relay to the house battery. Being as my switch and relay were mounted very close to each other and my battery was approx 6 feet away, I chose to use the "power-in" post on the battery switch as a junction connecting the B side of the relay to the "power-in" side of the battery switch for the house battery, so I only had to run 1 cable from the battery to the switch. This saved me from having to buy a $30 cable.

One less thing to worry about!

This product ends the worry about draining your battery with radios, sounders, etc while fishing. It isolates the "house" battery from the "start" battery but keeps them both charged from a single engine.

It does require some knowledge of DC circuits to install, but a careful reading of the instructions and some help from the West Advisor will get the job done.

Blue Sea Add-A-Battery Systems

Don't let the higher rice steer you away, these devices work and have saved several batteries in boats I take care of. Example: Auto bilge pump runs the house battery until dead, start battery is protected. Allows you to wire the entire system so that all devices are on bus bars and the batteries have just cables. Off is really off.
