older Raymarine L760 Instrument

[RitSim]

Came across this in deep storage. Don't have the power cord but would like to power up. Can someone tell me which pin is + and -? I believe the power pins are top right and lower left (3 o'clock and 9 o'clock from the internal tab)

Can you see the wires on the inside of the plug? They more likely can give you a clue.

don't have the plug

You have the female end... Are there wires behind the pins?
Wires connected to pins often give a clue as to purpose. Red & Black are your desired ones.

I could figure it out if I had the plug. I've looked on the Raymarine site and it appears the device is too old so the info is not there.

Looks like you need to open the case to I.D. the wires. bummer.
