Bought a cobra 1000 today. Had been sitting for who knows how long in an outdoor building. When I got it home and took the covers off, about a pound of dead cockroaches feel out, smh. Anyway, at first it powered up. Meters were stuck, meter lights burnt as well as the receive light. Had great audio and decent wattage. Ok, replaced those items and powered back up and the alarm started going off and the diode beside the audio transformer popped. Between the 220uf cap and transformer. Nothing powers up but the clock. Switch to 13.8 plug and have everything working but the clock. Not real sure where to start. My Madison did the same thing two weeks ago
