Guys & gals,
I have installed a new radio in my truck (sig. below) and the memory will not hold when I cycle the truck on and off. I have installed numerous radios in other vehicles and never encountered this situation.
I have triple checked the wiring, looked for faulty grounds, plugged and unplugged the wiring harness and I can only come up with one solution: The new radio is not meant to be in the old truck.
Could the ignition cycle disrupt the memory of the radio and cause the radio to wipe out the memory? I noticed the CB, air horn, and radio turn off when I engage the starter. This should not cause the radio to function improperly, just turn off and back on.
The memory line is hard wired through the firewall directly to the battery with a 5 amp in-line fuse and all the other wires (speakers, ground, remote amp, remote antena) are wired according to the diagram on the old GM AM/FM radio. What am I missing?
