I've looked in the forum and haven't seen a solution to the wiring problem I am trying to solve. I submit the below diagram and invite comments on whether it will work and achieve my goals plus any suggestions to improve it. Please note that I also have a three bank on-board charger, but have not included it in the diagram for simplicity.
My requirements:
With a three battery setup, provide for engine starting (single engine), backup start power source, 12 V house circuit and a 24V trolling motor circuit. I have a Perko switch available for the solution.
My proposed solution:
Battery 1 is the primary starting battery and is wired through the Perko as "Batt 1". Battery 2 provides the 12 V house circuit, but is also wired through the Perko as battery 2 for the occasional "jump start". This battery provides the -12V leg for the 24V trolling motor. Battery 3 provides the +12V leg for the trolling motor.
Note that the diagram includes a SPDT to switch the trolling motor from 12V to 24V. The diagram shows the trolling motor switched for 24V mode.
Thanks in advance for your comments and suggestions.
