Greetings all

Got a problem in a Motorola GM-340 VHF, it doesn´t power UP !!
I know a few tricks for GM-300, in this situation, but looking to the Gm-340 board, not the same at all !
I do no know what have caused this in this radio. Assuming the polarisation + - in the Power cable is the same has for the Gm-300, do not know what to check !
Any help ???

thanks

Hello Elmano. The Gm340 is similar to the CDM series in the US. Yes, the power cable is the same. Other people have experienced a no power up problem with this model.

Hope that helps.

Have you checked to see if it's programmed for ignition sense by putting 12V on pin 10?

Many thanks for your answers

..well, i do not know what is programmed in this radio, and can´t check it, because it doesn´t power UP !
..about connect 12v in 10 pin, can do it, if i know witch one is the 10 ! Can you help me in that ?,,and you mean connect 12v + or - in that pin ?

thanks

That would be +12V. This radio is negative ground.

Telex has an excellent diagram of the CDM series accessory plug in section 4.

You can have a radio with a corrupted firmware inside.
Try to read the radio.If it works,the firmware should be ok and you should program the radio with a default codeplug from the CPS folder.
