Re: 24volt trolling
Use the search feature. This has been covered many times including just a couple days ago. Since the boat is already set up for 12 OR 24 volts, set the switch on the panel for 24. Then check which two terminals in the receptacle provide +24 volts and ground. When you determine that, wire the troller PLUG so the red (+24 volts) and black (ground) match the receptacle. After that, leave the panel alone.
