Diode for reverse polarity protection
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? Thanks Kevin Minneapolis |
