Why does my CB only have black and red wires what are they to?

If you want a guess I would say black is - ground, + red is power and the other two wires are speaker positive left and right and the unit uses a common ground, you would have to ground each speaker - to the body. Be aware that is just a guess.

You have a battery a globe and a switch. It really only matters matter if you keep the circuit board(CB). Here's how mine was wired.


Red - Battery pos to switch to bottom of CB (BT+)
Red - top of CB (BU+) to pos contact pivot
Black - neg contact pivot to top of CB (BU-)
Black - bottom to CB (BT-) to battery neg

Or you could just bypass the CB altogether, wire the black to the black, and the red to the red. done.

The European models used the DIN spool that has a larger center hole than the U.S. models

Hello,
Here is the wire diagram for several common mics in relation to a 4 pin CB. Most recent 4 pin CB's such as Midland, Cobra, Connex, Uniden, etc can use 4 pin mics. The wiring is actually depending on the mic rather than the CB so long as the CB's are 4 pin as well. Once you go back to late 80's the 4 pin design was a little different. Anything new it is simpler.
Stock Mic 1- Shield (Ground) 2- Yellow (Audio) 3- Red (Transmit) 4- White (Receive)
Astatic - 4 wire 1- Shield 2- White 3- Red 4- Black
static - 6 wire 1- Shield & Blue 2- White 3- Red 4- Black Yellow NC

Heres a link to some information, and a picture of a red one.

Turn the knob ON to let the water flows out constantly until the red light goes off.

first check out the front for a circle with 27/81 this is the 40 channel (FM). if you cant find the circle it is (AM) and not used as much in the uk. if it means alot to you and your dad post it to cb communications shildon DL4 1HE and i will will see want i can do.

Hi, The most common cause for this problem is that the colour selection lever is set on white. Try setting it to Black or Red and see if that solves the problem. Ralph, Dial A Ribbon.

Try setting the grind to the coarsest setting, if you still have the same problem, check the wire connections to the board, it might have been reversed.

Hi,

It can be the steam valve or the boiler that is leaking.
