Anyone know if power can be positive ground? I suspect not, but hard to know what's in the guts.

It's been a while since I installed mine, but I don't think there was any requirement for power at all. It just plugs into the antenna port on the radio.

You don't need to ground it. It is power in/power out. You ground what ever you are powering thru the block.

As long as the heater plug is polarized (one wide prong, one narrow prong), there is no problem ... grounds are over-rated, not always needed. living in a "two-wire house with NO ground! yet still alive somehow ... retired electrician.

Get the voltage and polarity right and you should be ok. Just be careful not to fry it.

There is a way to ground it, but you must do it through a separate amp. Hope this helps!

It's still possible to have a decent signal. But the factors are what's between points A an B? The density of the blockage and are there any electric transformers.

You could technically make either positive or negative. Just dont mix them up. If youre asking a question like this you might want to have your home theater system professionally installed. Personally I use the white line as the power positive red....black is clear ground.Good luck

Although it doesn't tell you which wire is power or ground... Just have to figure it out. I would rig up a wall plug and hook up the wires and use a meter to see what is what. Hope that helps!!

For power it has one ground and one power. For the speaker out put it has 2 positive and 2 negative

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.

I don't see why not. The grounding is a separate thing, coming through the O of the two slit-eyed plugs. It is the magnetic energy of the earth itself, not electrical current.

I would check the watts and amperage first. I didn't but you might be on to something.

So basically you use one block as all positive and the other block as all negative. It's cleaner and easier. You can not ground one entire side and run hot to the entire other side. If you are looking for a power block kept looking this isn't it.

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

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.

Normally you put the disconnect on the positive terminal in a negative ground vehicle. However, after checking throughly through the system on on of my vehicles I couldn't get it to work. So I put it on the negative post just making sure there no other connections. Use an ohm meter to tell you if it's OK.

I agree that Robert's question may perhaps pointing to the potential reason. Grounding could be the key. Perhaps a portion of the fence wire is touching one of the metal poles (for example, not connected properly to an insulator on the metal fence post, accidentally touching the post; another example - if you are bridging two wires to power both, reviewing your grounding at the unit).
