We have a 6 year old UHF LMR in the truck that talks to a series of handhelds on job sites as well as other mobile LMRs. Yesterday a worker plugged their DC cooler into the truck socket and blew a fuse. Fuse was replaced, cooler removed, but somehow that circuit issue caused our LMR to crash. No inline fuses were blown on the radio, and it powers up just fine. It will Tx/Rx to a portable that is within 100 yrds/mtrs, but beyond a couple hundred meters it's now a $600 paperweight.

Has anyone else had this issue? Any solutions, Hints? Tips? Tricks?

Thanks in advance
