HELP!this is for you electrical experts...

I am installing a car stereo/cd player and 2 speakers in my galley. the diagram says i have to connect the black ground lead to a "metal surface of the car". do i have to connect to the trailer frame? can i ground it to something else? can i run it back to where all my other ground wires from lights, etc.. go? back to the battery?

thanks

Cleave, if you are running a "floating circuit", like most of us do, just run it back to your common ground point for all of your 12v appliances. Simple system for our simple life style.

The black wire should go back to the negative (-) terminal of your battery. It is called the ground wire because regular car electric systems are typically 12v negative ground....meaning that the car frame is "grounded" or connected to the negative terminal of the battery.

Run your hot wire(s) to the positive side and fuse them....and then your black ground wire to the negative (-) and you'll have tunes in no time!

And that, my good man, is what we call a floating circuit. No part of the vehicle(TD) is used to close the circuit. A torch uses a floating circuit.
