I have a Regency Polaris MT550XL scanning marine vhf set. It's an older <br />one, but still works good.<br /><br />Problem is the mike is missing, for some reason. I have a spare, but will <br />need to put a replacement plug on it. I need a 5 pin twist lok plug for the <br />unit, and a way to figure out which wires in the mike go to which pins in <br />the plug.<br /><br />Using the chassis socket, I can find a ground pin. That takes care of one <br />side of the mike element, and the PTT function. I can also power the set <br />and find which pin is 12v+. That leaves the mike element audio lead. How <br />do I ID that one (that only leaves three pins, so it's one of those)? Any <br />tattletale resistance to ground for the audio pin? I think the remaining <br />two pins are probably unused, after getting the three right for the mike <br />cord.<br /><br />And yes, I'm trying to get a schematic. That would make it much easier. <br />I've searched around and don't find one yet. Sams Fotofact may have one. <br />I've asked them. Their search engine doesn't come up with one, though.<br /><br />Where can I get a 5 pin twist lok mike plug? Don't know what the actual <br />name of such is, so may not be able to find because I won't be searching <br />under the right name for it.
