I fried a diode used for protection in a Bearcat scanner. It was fried
by connecting the wrong power cord (reverse polarity) into it.
The AC adapter puts out 13.8VDC and 700ma. I tried replacing it with a
IN4001 and it powered up the display and started scanning. However
when I plugged the speaker and display light back in it didn't seem to
have enough power to start it all up. The display flashes once and I
hear a pop in the speaker but that's it. The original diode had
markings printed which I think was RA above VB.
Any suggestions on another diode to try?

You might want to give us the model number of the scanner. Many Uniden
scanners use REGULATED power. It could be that when loaded by the
speaker and display light, the AC adapter no longer provides the needed
voltage.

My BCD396T uses a 6vdc 800mA REGULATED adapter. I don't think the use
of the 1N4001 is your problem. I think that a) the AC adapter was
damaged by the incident, or b) the scanner was damaged by the incident.
