1994 capri 1800ls duel battery installation

[wildvortex]

I just bought the boat and it only had 1 battery. cables and a battery switch(one with batt1, batt2, Both, and off. second set of cables were on the oposite side of the boat and I installed the new 2nd batt there. disconnected the origional battery to check and have no power to anything. There is a single cable on one side (left) dont know port or starbord sides :facepalm: this is in addition to the other two cables on that side. I am at a loss on install and bayliner manual simply states to have batts replaced buy dealer. any help would be appreciated

Welcome to iboats!

Here is a simple wiring diagram for a dual battery switch, courtesy of Silvertip:

You'll notice that each battery has both terminals wired, with the two negative terminals connected to each other.

BTW, port is left, right is starboard, when facing the bow. A good way to remember this is that left and port have the same number of letters.

Thank you! I had figured it out after pulling out a multimeter. Was forgetting that all accessories run from the one battery and was tring to disconnect that one to ensure the other batt was working.
