At a yard sale I found a lot of 8 Motorola Radius GM-300 CB radios, and one Motorola Max Trac CB radio. I also found a power supply rated at 13.8 volts and 12A continuous, 15A @50% duty cycle. I used this power supply to test all the radios, and all the GM300s were dead. However, the Max Trac worked! Am I using the wrong power supply? The GMs are rated at 13.2 volts, but have no amperage data printed on them. The Max Trac has no data whatsoever, but they all have the standard 2-pin power connector.
Well, I also found a Radio Shack 13.8 volt, 10 amp power supply, but the power switch is broken and I'm in the process of repairing it. Could it be that the GM300s need this power supply rather than the 12 amp pwr supply? The power connector wires had fuses in them and didn't burn out...I wouldn't think that 2 amps extra could fry them anyway.
It just doesn't make sense that all 8 of the GM300s are dead and the Max Trac works...is there a fuse inside and can they be repaired? I didn't pay much for them and if they're truly dead, I'll sell them as scrap parts.
