(snip) Curiously the power cord is blue and red wires.
I tried this on two different 13.8VDC power supplies
and I tried reversing the wires and no matter what they
short out the power supply. Any ideas? Anyone even
know the correct power requirement for this


Try grounding the case (radio housing) itself to the negative side of the
power supply and the red wire to the positive. The blue wire is more likely
a separate power input to maintain power to the memories. In a vehicle, the
red wire would go to the ignition switch side of the wiring, with the blue
to the battery side. The case completes the circuit when mounted to metal in
or around the dash. This wiring arrangement would allow the radio to turn
off with the ignition switch, while the blue wire provides constant power to
the memories.

Sadly, I have no clue about the identification of the radio itself. But,
if I were to guess, I'd say it sounds like a Relm sold with the Johnson name
on it. In other words, try checking the Relm web site (if they even have
one).
