Thanks in advance for any advice, I have a cobra 29 wx that I am using as a base. It's been working great for about 6 months and all the sudden yesterday kuhpoot! It was on for about two minutes and I had not keyed it up at all yet. I have done everything I can think of to diagnose, checked leads into radio and those are good radio has power inside of plug, where my real question lies is that I took out the on/off switch and test terminals. All terminals are hot even when switch is off. Nothing on radio will turn on, is it the switch or could it be another part in the radio letting power through when it should not be?
