    Battery Disconnect

    When hard wiring an Ultrex do both the positive and negative lines need to be disconnected before charging?

    If you don't have a battery cutoff switch already installed, I believe Minn Kota advises having power disconnected to the trolling motor while charging your batteries.

    Only one needs to be disconnected, and most put the cut off switch on the pos wire. I put mine on the pos also

    Gives you both circuit protection and a switch duty disconnect.

    That's what I use to protect myself TM. I also disconnect my electronics. With the HB,collector system, I just pull it out. At least until I come up with a better solution.
