If the return circuit is through the tram-line on the ground, and you choose to ignore the fact that it would play the role of a wire, then yes. But you're kidding yourself if you do.
A wire may be cut from the brakes. the turn signal wire is still connected
Your speedometer might not be connected if it does not work. It might also have blown a fuse if it is an electronic speedometer or it could have a wire that is loose.
The stereo is wired wrong. In this case it sounds like the ground wire of the stereo is hooked to the dimmer circuit. The ground wire of the stereo should be connected to the vehicle chassis.
it needs to be connected to a battery and a wire and a light bulb or load or whatever your trying to get to work. i dont know if it will be helpful. im a kid you know, im 9!
make sure amp remote wire is connected to p.cont wire and not power ant wire on the radio
The radio was wired wrong. Sounds like the hot wire for the radio was connected to the hot wire for the headlight switch.
I spliced mine in to the power wire on my raido. now if you had in installed go back and have them fix it.
Not sure what you mean by "wire communication". Are we talking like the phone lines, or the physical wires your computer is connected to, or did you mean wireless?
A light bulb is not lit when the swtich is not connected to the wire becasue there is no flow of electricity, specifically, flow of electrons. By disconnecting the wire, the bulb is no longer connected to the electricity source.
Check for a bad ground Im guessing that you connected the new CD player power wire to the illumination wire for the old stereo. Find a power wire that has 12v when the ignition is on.
I dont have a wiring schematic in front of me but you are looking for a wire in the old stereo connector that has 12 volts when the key is off, many people use this as their main power wire so that the stereo will work without the key but its not really made for that kind of use, the main power should be connected to the wire that has power only when the key is on.
Check fuse block for blown fuse; also check the wire connector terminal directly behind the lighter itself...wire might not be properly connected.
