Thread: Battery Disconnects Project

Decided I wanted to install a set of disconnects on my cranking and trolling batteries to allow me to isolate them when the boat is sitting.

Scavenged a spare set of heavy duty disconnects up at work. Found some scrape 4 gauge wire and cut the lengths I needed. Crimped a ring terminal to the end of each. Using a stepped bit, drilled my mounting holes. Mounted and wired the disconnects on the boat. Made up a few labels to make it easy to distinguish which was which and what position they were in. A quick test to see if everything was working properly, and all done.

Looks great. I'm sure you checked the amp rating of the switches. My only fear with doing this is being around water and salt, every connection you add is another breakdown point waiting to cause a problem. Make sure you keep a good check on them and pay up your SEA TOW. Nice job and thinks for showing us.

These are actually CAT battery disconnects. Commonly found on construction equipment and large stand-by generators, both 24v and 12v, so very confident of their amperage capacity and resistance to the elements.
