    Trolling motor battery wiring

    Is this providing 24 volts or 12 volts?

    I am electrically challenged an on my other boats I tied the batteries together and ran 2 heavier wires to receptacle.

    This boat runs 4 wires to receptacle.

    I just want to make sure this is a 24 volt set up.

    The answer is : Yes.

    That’s 12/24 wiring and both are available at the plug. The plug has a jumper in it to make the 24V connection.
    If you have integrity, nothing else matters. If you don't have integrity,
    nothing else matters.​

    Yes, but that's the old way of wiring when there were 12/24v switchable trolling motors. Most people now have straight 24v TM's so you can eliminate two wires from the battery to the plug, usually White and Orange, and then connect the batteries in series in the bilge. Most TM's now come with only a 2 wire connection for the plug.

    A- and B+ is the 24 volt tap IF there is a jumper in the plug between A+ and B-.

    There is a jumper (A- and B+ are connected).
    If I wanted to move to a 2 wire 24 system..........would I need to break the connector off at the receptacle?
    I then would add a jumper at the batteries.

    Just use two wires, one from the positive battery post of one battery and the negative post of the other one, with a jumper between the two unused battery posts.
    There's nothing wrong with a 4 wire system.

    Currently it's a 12/24 volt. Staying with 4 wire for now....just losing the 3rd wire to get rid of 12v. Guess that's all I have to do to get rid of the 12v.

    Thank you.
