I am moving a 18HP Horizontal engine from a GT/18 Model #917253740 to a GT/18 model #917254410.. I have the Owners Manual for the first tractor but not the second, Can anyone help me on that manual for the 917254410?

Second Question: The engine going in has a 2 wire connector coming from under the flywheel (Red wire and Black), Is this DC voltage? Or AC? Is the Rectifier under the flywheel? The Engine BTW has no information stickers or tags that I can find,
Do they hide them somewhere.

Third Question: The Magnetronic Ignition ( or Coil as I would call it ),, Does it need 12v supplied for the tractor to start? I am thinking that the flywheel magenets and the coil would generate its own voltage and step it up to high voltage for the Spark plugs. Right? The Schematics say that the magnetronic ignition is grounded to stop the engine.

I can post pictures if needed..

Thanks for any and all help

Red is DC for battery charging. I believe the rectifier is part of the connector. (nominal 3 Amps)
Black is AC for headlights. (5? Amps)

Magnetron doesn't need external power.
It should have a kill wire to ground in order to kill spark.
