Default Voltage reducer question

I am trying to hook up a voltage regulator. Wondering where to connect the positive and negative wires for the unit. I was thinking the + and - posts with the wires that go to the charge receptacle (even though these are on two different batteries.)

Also, this capped 4 wire plug is connected to the negative post there. Anyone know what this is or if it should be hooked to anything? Thanks all.

If you are talking about a 48 to 12 volt reducer, go from pack positive and negative.

Yes that is the one.

I am still new to the cart world so I want to be sure what you mean by pack positive and pack negative. There are 6 batteries. I was asking if that refers to where the wires for the charging receptacle hook to. It is positive on one battery and negative on another.

The reducer I bought has 5 wires. + and - to run to the batteries. + and - to run the accessory. And a yellow wire that says it goes to the ignition switch.

Yes that would be pack negative and positive. Not all carts run the charging wires that way.

Get a digital voltage meter if you do not have one. You will need it for anything you do with the cart wiring.

Your reducer is probably (the 5th wire) designed so it can be "triggered" by the switch.

Go from the first batteries negative post to the last batteries positive post. This way it evenly pulls from all batteries. Otherwise you will shorten the life of the batteries you hook too.

I do have a voltage meter. Iím familiar with working with the 12v system on my old car but this 48v is a new animal.

For the yellow wire that triggers the reducer via the key switch, do I just tie into one of these wires going to the back of the switch? Thanks.

Find the one that has no power when the switch is off and tie into that one
