Battery config - wiring diagram?

[ifishforbass]

Does anyone have a wiring diagram of how you should have your batteries configured in a 36v TM / Starting Battery - jump switch (position 1,2, and 1&2)?
Thank you!

I'm not clear on what you are wanting to do. A dual battery switch isn't really the right choice for jumping a battery in a bass boat. You flat can't use any kind of jump system if you have a US2 trolling motor.

I don't have a diagram, but maybe I can lead you through it. You will need to identify the trolling motor battery that feeds ground to the trolling motor. This is the battery that we will be dealing with, known as battery 1. The cranking will be simply cranking:
Negative battery 1 to cranking battery 1
Positive cranking 1 to switch 1 or A
Positive battery 1 to switch 2 or B
Outboard and any accessories you would like to cutoff when the switch is turned off to "C" common.
Since most larger outboards use a 4ga wiring harness, the cable from positive cranking 1 should be 4 ga.
The others can be 6ga since they will act as a "booster cable" -- unless you turn it to "2", then you will be pulling off the trolling battery and will need 4ga for both the ground and the wire from the switch to the positive of battery 1

This is what I have in my boat. Installed at factory. I have (1) cranking battery, and (3) trolling motor batteries. I have both pos and neg from the battery feeding the negative to the TM hooked up to the switch for jumping.

I don't understand this statement. The negative will connect to the negative. Only positive wires will connect in the switch.

My apologies. Here is my config right now.

Number of switch?

[Jonestrollingmotor]

That is a dual circuit switch. A dual circuit switch from Blue Sea Systems has 4 stud terminals. The above diagram see post 7 is not using a dual circuit switch.

Do you have 4 stud terminals on your switch....your diagram only shows 3 wires at the switch?

Lou, I've used this switch as well as other brands in the same switch many times. It only has 3 studs in the back. An A, B, and common. It selects, as it shows, battery A, Battery B, or both.

Yes, my error, I was editing .

Can i asks a silly question.............


What is the benefit of the switch about? What does it accomplish?

[ifishinxs]

The switch allows you to turn off all power to the boat. It also allows you to switch from battery 1 to battery 2 should battery 1 fail. It makes working on you boat safer to work on with battery's turned off rather then disconnecting the battery

Got it!

I have a master power switch, but not the ability to switch to a secondary battery. I carry jumper cables if that is ever needed.
