That's not negative or positive terminals! According to manual that's adjustment potentommeter to change from CE compliance to FCC .

Something is wired wrong. You have to pull two different hot wire power sources. One for the Backup Camera at the 'rear' of the vehicle that taps into the hot reverse vehicle backup light wire, and one at the 'front' of the vehicle for the Monitor as well. Both the front and the rear must in addition be grounded to vehicle body ground. The hot wire source at the front of Vehicle Monitor can be any hot vehicle wire tie in but must be away from the fuse box to help prevent engine ignition 'run' static. I will hand draw a wiring diagram and return to this post and put it up in a while.

Sorry- looked at my controller and the positive is shared. Hook the negative from each panel to separate neg (-) terminals. Both positives share one terminal.

I don't have any experience with your keyboard, but usually you'll find a sticker near the plug that tells you what voltage and amperage it needs from its adapter. Also, if there's a little diagram that looks kind of like a "C" wrapped around a dot, pay attention to which one is labelled positive and which is negative. If you can get that info, you can just buy an adapter that matches that description and you're in business. Good hunting!

Simply hook up the negative and positive and plug something in to test. If you don't get see the device being charged, reverse the wires. Due to the low voltage, you won't damage anything.

Hi. This is what I would look at. I would start with checking your Fosmons' power adapter. Is it plugged in? Is it delivering 5 volts? Is the power light on the Fosmon lit and not dim? If so then you can check the Toslink cable on the Fosmon end. Is the red light coming through it? Did the Toslink cable seat down properly in both devices? They kindov pop when they are fully inserted.

The one I ordered it for was a TX something... I don't remember the numbers after the tx, but it's a small basic unit.

You have to look near socket on device, or on original AC Adapter. On the Velleman PS, it's clear how to connect adapters for center positive, etc.

You need to determine if its 24 vdc or 12 vex. If its wired both pos. And both neg. Together its 12 vdc in parallel. If its wired straight though from one battery to the next pos. To neg its 24. You hook the pos. From your battery to the pos on the controller terminal with pic of the battery. And neg like wise. That should be it.

you know some of the others are right I made an end two plugs and the only issue is third wire is for reverse energy pack. it works can't back up.I am looking for that 3 pin plug pack also

tough question sight un seen but sounds like your attaching the load wire to same termination bracket. also the outlet may be defective. If it is doing it on more than just one then it is the attachment location that is wrong.

Connecting only Tx, Rx and Gnd works for all of my designs I have a few 5volt ones and a few 3.3volt. None of them seem to have any issues.

I assume you're talking about the barrel connector on the plug and its mate in the battery? The outside is return (negative) and the inside/recessed pin is power (positive). That is for safety reasons, so that if the barrel connector touches something grounded it doesn't short.

There are two "jump cables". One negative (black) and one positive (red). They are neatly wrapped around the back of the unit. This is a very good product!!

all three answers below are correct please rephrase your question im not sure why you would want to install a plug "pig tail".

Not sure about that as mine is negative ground. That said, it should be ground polarity insensitive by reversing the connections.
