    The same. IF in doubt, put the 3rd battery between the two you have, with positive to negative, one from each current battery.

    You likely have it jumpered in the plug. Connecting a new battery between the existing batteries would be creating a direct short across the new one. You need to verify that you have it jumped in the plug, then wire the batteries appropriately.

    With two sets of wires (one set to each battery) and a 4 prong plug you will most likely have it jumped in the plug. Disassemble the plug and look for a jumper between two of the wires. If so, you can take the positive off battery 2 and place on battery 3 positive. Then place a jumper from battery 2 positive to battery 3 negative and have 36V on the same connections at the plug that you previously had 24.
