Pinout for powercord - Motorola Nautilus 440

[WA3EEC]

Does anyone have a pinout for the power cord for a Motorola Triton Nautilus 440 VHF Marine Radio. I assume that the radio is about 30 years old.

There's a 6 pin connector on it's rear.
Thanks,

Can't say for sure on that one but most of the old radios like that had a diode across the power pins which will tell you the polarity as the diodes were to prevent reverse polarity. They also often paralleled two sets of pins for current handling Power would go across with posiitve on the negative side of the diode and the negative across the positive side.
