    Weird that the Vic-3 isn't being powered connected that way... cables are working fine since I have them connected to an old 1777 radio deck.

    polarity ?

    You're talking about an AM-1777, right? So, that should be actually mounted onto an MT-1029. If the MT-1029 is working and the MT-6352 isn't working, I think I'd suspect that the wiring is damaged in the MT-6352, or someone rewired it on purpose for a currently unknown reason. If I recall correctly, those power strip aren't too hard to disassemble. As well, if you do the test I outlined in the thread you started, that will show if polarity or continuity is the issue before you take apart anything. I'm very curious to see what you find out!

    The CX-4720 is the standard 4 pin power cable that was used with the VRC-12 series radios. When they started fielding the Sincgars series radios they changed the material on the outside and gave them all new numbers but in most cases their the same wiring wise. You'll also notice some 45 degree cable guides on the Sincgars connectors.

    CX-4720 = CX-13302

    CX-4721 = CX-13303

    CX-4723 = CX-13300
