So, my CB recently mysteriously started blowing fuses as soon as they touch the fuse holder terminals. My best efforts at google searching seem to indicate that the “Reverse Protection” diode has failed.
I’m not concerned about my ability to solder in a new one, but ai am concerned about why it failed.
So far as I know, the polarity is not reversed. The system worked for a while, then I had an antenna cable problem and didn’t use it for a long time while I replaced and rerouted the cable. I also soldered on a new, longer mic cable. This involved soldering the mic and the connector to a new cable.
After this, fuse failures started.
Could I have done this? What else can cause this?
The diodes are ultra cheap, but it appears that I have to buy a package of 100. Does that mean they are crap and will fail all the time?
I think I need one of you experienced electronics and comms guys to weigh in here.
CB is also cheap... Uniden PRO 510XL.
100 diodes will cost 1/2 as much as replacing the unit. The pin comes from my under driver seat mount that will take several hours to swap.
Thanks for the knowledge!
