Question about Cobra 29 LTD CB Radio
I'm trying to hook up my spare radio in a different truck while mine is in the shop. The radio is the one that was in my Kenworth when I bought it and it worked fine. I took it out to put in a hotter radio and have kept this for a spare. I am now trying to hook it up in a 2004 Freightliner and the fuse blows out each time I try to plug in the power cord. I'm sure I have the polarity correct
I had the same problem with a 25 that was just disconnected for replacement. I found a shorted diode right where the power cord came in. I also didn't like the way the electrolytic capacitor right next to it was charging so I changed it also.
I am sure the 29 will have a similar setup. I you want I will look up my schematicof a 29 and tell you the numbers to check.
Of course it is also possible somehow too much voltage was applied to the radio. In which case the previous repairs will almost surely be needed.
I hope this helped, Good luck
