Question about Radio Communications
Having issues with this radi, Its a new install and we tried 1/ moving and replacing the anyenna, 2/ tried another new raio. Always seem to have the same problem. I checked power in on transmit engine off and it styed above 12 volts, however I am still suspect on the power in..... Any thoughts?
31, hi, is this some sort of a business band radio or a CB radio? Make sure your power wires are large enough to carry the amperage the radio needs. Have you done any kind of SWR check on the antenna system? Make sure the coax does not have a short in it. Make sure you did not splice the power wires with a "scotchlock", those thing do not make a good quality connection. Hope this helps you, and if not reply back here with some more info for me to help you. Thanks Mechanic

Tips for a great answer:
The body control module (BCM)
The powertrain control module (PCM)
With the ignition in the ON position, battery positive voltage is supplied to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid receives a ground from the BCM. When the automatic transmission shift lock control solenoid is energized, the shift lever mechanically locked in the PARK position. When the driver presses the brake pedal the PCM sends a class 2 serial data message to the BCM. The BCM turns OFF the ground control circuit and this de-energizes the automatic transmission shift lock control solenoid. When the automatic transmission shift lock control solenoid is de-energized, the shift lever may be moved out of the PARK position. The BCM determines transaxle shift lever position through a class 2 serial data message from the PCM. The PCM receives inputs from the park/neutral position switch and determines shift lever position. When the BCM receives this information and determines that the shift lever is out of the PARK position, the automatic transmission shift lock control solenoid ground is opened.
