Aft batteries
|
|
Aft, we have 3 batteries. The two starboard batteries power the starboard transom mount trolling motor, and the port battery, as well as one battery in the forward hatch power the port 24v trolling motor. If you look closely, you can see a relay on each side. The owner wanted to be able to control these trolling motors from the bow. Thus, a "Big Foot" switch will control them. However, due to the amp draw these motors pull, the 10 AWG wire that all these switches have, the current loss would be too great. The run of that length would actually require the use of 4 AWG wire, and the 10 gauge would cause major current loss. "A chain is only as strong as it's weakest link."
Thus, the solution was to use 24 volt continuous duty rated relays. Not only did it eliminate the need to run full power through the mediocre switch, it also shortened the run length drastically, allowing the use of 8 AWG wire on the starboard side, and 6 on the port, as that has the split battery setup.
