I have a 94 Crownline 225BR and while installing a new radio, the antenna wire on the boat side (as opposed to the wire on radio side) became disconnected from where ever it was screwed to on the boat. The radio installation directions state that the radio will not work (which it does not) if the antenna is not hooked up properly. I am unable, however, to find where the wire was original screwed to the boat. I tried hooking it up to the ground for the radio but still nothing. The radio worked before the wire pulled out so I know that everything else is correct. So, does anybody know where this wire was originally screwed to?
