DavisIslander Posted June 13, 2022 Report Share Posted June 13, 2022 So far so good! New charger, new 60 amp circuit breaker and being the dumb*** I don't remember where the battery switch lines attach. Any and all help is appreciated. I must report, that storage compartment on the 04 RF18 under the steering wheel is a BEAR to work on/in. Tiny! Thanks and Tight Lines.

smilemaker Posted June 13, 2022 Report Share Posted June 13, 2022 I use the breaker as off on for the trolling motor. I know you are not supposed to use it as a switch but it is 24 volts and i want no confusion with switches. If you want to use a battery as a backup on your diagram use battery #1. Connect its negative to your common ground and its positive to #2 on a 3 way switch Quote Link to comment Share on other sites More sharing options...
DavisIslander Posted June 13, 2022 Author Report Share Posted June 13, 2022 I've updated the image, I have a house battery for the motor, etc. Quote Link to comment Share on other sites More sharing options...

DavisIslander Posted June 13, 2022 Author Report Share Posted June 13, 2022 Skip, I only have a 2-bank charger. Quote Link to comment Share on other sites More sharing options...
fin-addict Posted June 13, 2022 Report Share Posted June 13, 2022 Your TM set up looks correct. The neg and pos from batt switch should go to the main fuse block if not mistaken . Don’t know your exact set up. I also use my 60 amp as the TM on off switch. Quote Link to comment Share on other sites More sharing options...
Hobo Posted June 13, 2022 Report Share Posted June 13, 2022 DAVISLANDER, Skips diagram is the best and most practical battery set up for a boat with a 24 vdc trolling motor IMHO... One battery serves a dual function as both a cranking battery as well as part of the 24 vdc supply for the trolling motor.... I've been using this system for years and have never had even a hiccup... The only suggestion I can add would be to rotate all the batteries about once a year and use matching size 27 or 31 AGM batteries... If you don't intend on upgrading to a three-bank charger (which would be the best option) you can always add just a single bank charger,,,,, or swap one set of your existing charger leads between two batteries but this would get old quick... If you don't want to manually switch charger leads from one to the other another option would be to use another separate battery selector switch on one of your dual charger leads and switch from one battery to the other... 1 Quote Link to comment Share on other sites More sharing options...

Quote The neg and pos from batt switch should go to the main fuse block if not mistaken You do not have a negative lead on a battery selector switch... Nothing but positive leads connect to a battery selector switch... Negative are not switched... 1 1 Quote Link to comment Share on other sites More sharing options...

Thanks Hobo, I don't plan on changing to a three-bank charger. Knock on wood, I've never had an issue with the motor charging the cranking battery. I don't have a ton of electrical demands on this boat so I've never had any type of charger for the cranking battery; just the motor. The TM batteries are 37's and less than a year old. Correct Fin-Addic, nothing but Positives! Quote Link to comment Share on other sites More sharing options...
smilemaker Posted June 13, 2022 Report Share Posted June 13, 2022 Are you saying you have a house battery and crank battery plus two trolling batteries. Or does one battery run house and crank. Quote Link to comment Share on other sites More sharing options...
smilemaker Posted June 13, 2022 Report Share Posted June 13, 2022 Slyshon s diagram is what i was saying. If you connect your charger to the two trolling batteries and put your switch to both you can charge all 3 batteries at once with some limitations. Crank and #1 will be in parallel and share amp output of the one bank. Battery #2 will have its own bank and charge twice as fast. Quote Link to comment Share on other sites More sharing options...

smilemaker Posted June 13, 2022 Report Share Posted June 13, 2022 Keeping it simple follow diagram from slyshon and hook 2 bank charger to trolling batteries. Charge crank with a portable charger as needed or just put switch to "both" and give it longer to charge. Quote Link to comment Share on other sites More sharing options...

So again, where do my switch wires go? Quote Link to comment Share on other sites More sharing options...
smilemaker Posted June 13, 2022 Report Share Posted June 13, 2022 The switch is diagramed in slyshon attachment. #1 pole is cranking battery. #2 pole is your first trolling battery positive.(this pos also goes to the neg of the other trolling motor battery to create 24v) The center pole goes to motor and to the pos on the fuse block.
