If I already have a ring connection to positive (aftermarket stereo) can I connect the negative ring lead to any good ground?

I am sorry I cannot help you. My neighbor does this stuff for me. I am mechanically challenged.

Usually the center connector is Positive. Use your DMM to determine the polarity.

Yes you ground your device anywhere you find a good ground and then run your red(positive) wire to the fuse box using the Add-A-Circuit.

I'm not sure exactly but I know the boss unit does have another plug connector that doesn't use the rca at all. you may need to attach that pug instead. if not use the left input and hope for the best. because it's bass it shouldn't be too noticeable. also maybe go to a car audio shop and ask one of the guys and see what they say. I wired mine from the rear speakers using a line output converter but that's essentially what you already have coming from your stereo. sorry that I couldn't be more of a help. good luck!

While I was researching electric jacks I saw this mentioned several times. I just ran a ground wire directly to the battery. No problems.

When it comes to speaker wires it doesn't necessarily matter which is which, they will work either way, but optimally if wired correctly. If it is shorting out, your positive wire to the radio, either the red or yellow, or possibly blue, are cut and grounding out your system either on your adapter or higher in the system. It could also be in your radio itself to where your radio is faulty. I've had both scenarios happen with me. Hope this helps.

It's to ground it. .. if needed. I've run these in two different cars to get rid if engine noise and never needed to connect the brown/ground wires. If you still have noise after you connect the rca's, then you can try connect the grounds.

Yes it should help, I had the static noise whenever the stereo was on. This product instantly took that away without grounding it at all (Brown cables on product)

It might but probably not as as simple as it sounds its not a yes or no answer. There are other ways to determine if the door bell is bad or another component BUT one would have to physically look at your door bell itself to see how that door bell button is configured. Mainly because this tester is basically a light bulb with a clip and a probe attached to it. As such it needs a positive voltage on either the probe or the clip and a negative or return on the other. Were you to connect this to your door bell all you would be doing would be connecting it to 2 points on the same positive wire as the negative( which you have to have in order for the tester light to come on) is a straight wire that goes from the ringer back to the door bell transformer BUT it might be behind the door bell winger. A typical door bell has 2 wires that when the door bell is pressed make a physical connection and allow the low voltage ( 6 to 28volts) to pass thru the button and go to the bell- ringer- chime and that makes noise. These hand held testers like this are generally used around automobiles & such where the negative (return) is the car battery which is physically connected to the vehicle body and you can attach the clip to any clean metal surface. Door bell buttons usually outlast the other parts of the system... Transformer and chimes typically go bad first.

If I remember, you can use either the positive or negative terminal. I connected to the positive side. You will need to purchase an additional cable Autozone). I used a 9" positive cable. I connected the positive cable from the battery to one side of the switch and the additional cable from the other side of the switch to the positive connection point. Did not have to touch the negative. Hardest part was creating a hole in the battery case (RV trailer) to locate the switch. It only took a few minutes to install and has worked without problems for a year. Hope this helps.

On the controller, there is an opening for a small plug. Drawing on the case shows center lead is positive and outer shell in negative. You can buy this plug at radio shack. Take a length of 16 ga. speaker cable (the cable with a silver and copper colored wire is easier to keep the positive and negative marked. Solder the wires to the plug and connect the other end of the cable to the 12 volt system of the RV. Be sure to fuse the positive wire where you connect it to the RV 12 volt system. I think we used a 10 amp fuse.

You can ground it if you want but its not necessary. Mine works great ungrounded.

Hi Brandon, There are several ground screws on the bottom of the control board, so I just used one of those. All grounds are at the same potentional so no need to change out the ring connector for a spade.

I believe it depends on the version. The newer model does not need it? Check their web site. Its always best to ground everything though.

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.

The red wire connects to the center pin, the black wire to the outer ring. As far as polarity, it depends on what being plugged into it. If you want a pos. center pin connect the pos power lead to red. For a neg. center pin, connect the neg. power lead to the red wire.

I have used it without grounding the preamp. It worked perfectly, and, the instructions say nothing about your question, so I don't think it is a problem to worry about.
