Most golf carts emit 36 or 48 volts. A voltage reducer allows the voltage from the entire battery to be reduced to 12 volts. This allows the electrical load that comes from accessories to be evenly taken from each of the six batteries. Otherwise, there will likely be burnouts, and accessories such as radios might cut out every time the engine is turned on.
The batteries are located under the seat. Lift the seat cushion to expose the batteries. There should be six batteries.
Disconnect a terminal to break the circuit.
Connect the voltage reducer's B- terminal to the negative terminal on battery one.
Connect the voltage reducer's +12V terminal to the accessory's hot wire (positive, probably red). The accessory could be a light or a radio.
Connect the voltage reducer's -12V terminal to the accessory's ground wire (negative, probably black).
Mount the voltage reducer in the dash area of the cart.
Reconnect the initial terminal and reattach the seat cushion.
