There are two connectors in the base of the unit. Which goes to the positive and which is the ground?

One the ones that I have the + and - terminals are marked on the bottom. The + terminal is the one closest to the center and the - terminal is the one closest to the edge.

The positive terminal is always red and in lighter type socklets the middle terminal is always positive. The ground (or black) is usually like a surround as the lighter or the power supply plug is inserted into the socket the heating element or "button" is pressed against the middle, power is supplied and the ground circuit is completed through the outside of the plug.

Yes. The positive pole is on one end and the negative pole on the other. It is very easy to hook up and operates great.

I believe that it is the larger one. It should show a + and - at the base of the terminals. If not marked with + or - it will have a red dot on the positive terminal. If still not marked for some reason, then there is a capacitor soldered to the + terminal. It will be a little round thing soldered to one of the leads that goes to the tweeter. This is the positive terminal.

The set of ground tabs is your Negative (ground). Normally, you'd directly connect the set of ground tabs to your vehicle chassis ground. Each fuse's fast-on (0.250") connector is Positive. You can use the ground tabs on this fuse block if needed, depending on how you're wiring everything.

There is no positive/negative wire. One end goes into the outlet and the other goes into the device.

Don't no name but the connection one is vertical the other is horizontal on a plug in connection.

Positive & Negative on the board is the 12 volt power input. The other two connect to the motor

The + terminal connects to Battery/Fused positive; the light symbol terminal connects to the load/accessory (where the light illuminates when switched on). Connect chassis ground to the ground symbol terminal.

The one I have is 2 pads on one wire and another 2 pads on another wire. There are 2 spots in the unit to plug in 2 wires. One to the left side and one to the right side Hope this helps

The black wire connects to the battery or positive connection... The ground is obtained through the bolted connection of the jack base to the trailer tongue. Be sure that there is a good metal-to-metal connection when bolting the jack in place.

The end is a pair of wires that you will need to connect to a positive and negative source.

The positive and negative wires from the solar connect to the appropriate connection in, in the contrôlée. The positive out goes to the battery + and the negative out goes to the battery negative post. The controller is not grounded, no ground terminal.

A ground wire can easily be connected to one of the screws on the side of the unit. That's how I installed mine and got great results.

The Positive lead is clearly marked if you have the one with the rubber MC3 connectors, The Female MC3 (the one with the hole inside if looking at the face of the connector) is the Positive Wire. If you look at the rubber boot it has a + molded into it

I don't have a schematic but the negative terminals measure zero ohms between them. The positive terminals show a high resistance. So I would say it is common negative. The two mounting pads appear to be isolated from the rest of the circuit.

One wire goes to positive, but the other wire just needs to be grounded to your vehicle, not the negative wire, this should fix the problem.

Middle is positive or "hot" wire. The 2 ends are the negatives and brass is ground.
