I installed a new battery and accidentally crossed the cables. Fortunately everything was switched off except the vhf radio. I saw quickly that the cables were wrong and corrected them, but of course the radio was dead. I checked and it had a fuse, which was blown. I replaced the fuse, but now when I turn on the power to the radio the fuse blows, even if the radio is off. Anybody know what’s up with this? I would think that the fuse wouldn’t blow with the radio off. Any help would be appreciated. Thanks -
