Is this positive or negative ground? Are all the negatives or all the positives tied together?

The external case doesn't appear to be connected to any terminal, there are both + and - terminals for the battery and array. I don't believe it will matter whether your external system is positive or negative ground.

In a Direct Current (DC) system there is a Red and Black wire, the Black is mostly always ground unless specified by the manufacture as otherwise.

The positive and negative wires from the solar connect to the appropriate connection in, in the contrle. 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.

Chris, Most of these DC power supplies are center positive. The connector configuration (polarity) is always displayed on the front or the back label on the PS.

If there is color to the line- I'd imagine it's positive. The line that showed up (within 5 min for me) had no color. It sort of looked like a shadow of a line.

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.

There is a power cord coming out. They are 2 wires. The only hard part is there is no documentation as to positive vs negative lead. I tested both directions and chose which worked best.

Positive and negative from battery on one side; positive and negative to the 12v motor on the other side. There shd be very small print that illustrates which side is which

There is two stray wires for positive and negative. You can connect it to batteries. Connect it to a 12 volt source i.e. inside cab lights.

You should be able to wire together all positive an all negative and just connect one + and one - to the battery. The current draw is fairly low so it should be no problem.

make sure the positive is connected to the positive, and the negative to the negative. i have many battery tenders and solar panels that all use this plug and some are wired one way and some are wired the other.

I believe this unit has no ground terminal but is hooked directly to the batteries which should have a negative ground. Since the panels are also grounded, it all should be fine.

negative or positive voltage is simply a reference to ground. reverse your power connections (leads) and you now have negative voltage. it does not have a dual output for both positive and negative voltagesgood luck

The positive ( red) i connected to the wire that goes to the reverse bulb. And the negative to any screw in the chassis. Ground.

It's the polarity which is reversed and don't ask me to explain that. I finally gave up and started using batteries. It works fine and the batteries last a pretty long time. Good luck.

the left hand terminal is negative. and the photo is correct showing red at the right terminal...red is positive.

My opinion to your direct question is yes, it is no-good. I think the whole thing is no-good from the start. A total waste of money.

All points on a bus bar are electrically from a single point. So if you wire one point to the negative terminal, then all posts are negative. If you wire one post to Positive, then all posts are positive. You would never wire both the positive and negative together on the same bus bar or you will have a firery short circuit.
