Yamaha 12v outlet plug

On this new to me 2003 Yamaha 15 2st I have a 12v outlet. Does anyone know what plug is needed to fit the socket... Yamaha specific or is there something generic available?

Seems to be a male/female combo.

Well it's a bit puzzling actually. Think I need to look into it.

In the manual it says it's an AC 12V 40/60/80W power outlet that must only be used for lighting and not to connect to a battery.

The OB is fitted with a lighting coil plus what Yamaha call a regulator/rectifier so I'd have thought it would be 12V DC suitable for a battery.

Here is the diagram in the workshop manual. I've found a comment on the net to charge a battery you need to use the currently unconnected red wire plus an earth.

Looking at the diagram it's not regulated just straight from the coil,You could start her up and put a meter across it David to prove

I hadn’t looked at the diagram until putting the image up just now. It’s odd the plug is straight off the coil and in the standard setup the regulator/rectifier is connected in parallel to the socket but it’s output isn’t connected to anything.

I’ll have a probe with the multimeter when it’s next running.

I would drop a meter across I'm not an electronics man and not familiar with the symbols they could be semi conductors only allowing DC to flow from the regulator
