Yanmar YSM 12 R Ignition key switch

[morganoutisland]

Hello all,
Someone removed the ignition key switch on my 30' Hunter with a Yanmar YSM 12 R engine. I know that its a 2 post (off-on) key switch. I'm just not sure how to wire this, it only has 4 wires but with my luck...lol

The key switch should be 3 post unless you have a start button. 1, power to switch 2, for alt and accs 3, start position with spring back.

1) There is power in from the batts
2) Power out to the starter solenoid control circuit (not needed if you have a deeicated start button)
3) Power out to the "ignition circuit" (the voltage regulator and hour meter and anything else that needs to be on only when the engine is running)(the dedicated start button if equiped)
4) Power out to the acces (not many of these but stuff you would want to turn on with the engine running or not)(the head lamps on a car are a good example but with a marine diesel I can't think of a single one off hand)

Needed a key for my Hunter 25.5 with 1gm10 Yanmar. Norton's for Deltaville Va fixed me right up. I understand there may be only two type and cut keys. Call them and ask.
