Question about Cobra 148 GTL 120-Channels Base CB Radio
The wires inside my turner dm7800 base mic has come away from the circuit board they are red white and blackdont know where they go can you help please
don't worry about wire colors. pin 1 is ground. some mic's need two wires for ground depending on the PTT switch used. pin 2 audio. pin 3 TX pin 4 RX.. thats all there is too it. once you know the pins all radios are easy. galaxy/connex/genlee same pin outs except pin4 isnt' needed for RX but can be used for 9v dc to power micropohnes.

ALLways start with ground. Find ground on radio pin with ohm meter. EVERY thing operates off ground. Once you find ground on radio....solder your ground wire on mike cord to corresponding # on mike jack. Once you have ground on proper pin then all else is elementary......use ohm meter to see which wires are TX and RX on mike.....last wire is audio wire.
