18hp kohler wiring

[BahrA]

I put new wiring harness on my Power King 1618 and 2 wires going to the engine are orange and blue, the wires coming out of the engine are black and white. How do I hook them up? The engine doesn't have a coil.

 

[Dale2]

The white wire should be the kill wire and the black one should be the charge wire

Take the flywheel cover off. There has to be a coil someplace.
One wire will go back to the ignition coil. The coil will be close to the magnets on the flywheel. That wire is the kill switch,
The other wire will be going to the charging coil under the flywheel, That wire will go to the diode.
The color of the wires are insignificant,

I guess that means you don't think Dale2 knows what he is talking about? If he has it running, I would think if he grounds the white wire and it doesn't start and then takes the ground off of it and it starts I would be convinced what Dale2 has has said is correct. It would probably be good to make sure you have a way to immediately disconnect the ground if it shows signs of firing so the alternator is not damaged. It might be wise to connect the ground to the circuit through a 2 or 3 amp fuse.

It would be helpful to know which 18HP Kohler engine the O.P. is working with, depending upon when the tractor was built it could have an 18HP single-cylinder OHV engine or an 18HP horizontally-opposed flathead engine. IMHO, encountering a magneto ignition on either would be unusual.

 

[T.R.K.]

How about pictures of the engine and tractor? That way we could be more specific or at least our advice wouldn't be as far off in left field.

I was guessing a K-series Kohler. I guess it could be a Magnum engine in there too. I never encountered may Magnum engines, but the ones I have worked on were all magneto/electronic ignition. The Kohler K-series could be equipped with magneto under the flywheel triggered by points on the side of the engine.
But like W.O. said, there was even a Command series engine that was rated 18 or 19 hp.

I am also thinking/hoping this wiring harness you are installing is supposed to be correct for your tractor. Is it OEM? If it is, maybe the supplier could help you with a wiring schematic showing how the wires connect to the engine on your tractor, assuming of course that the engine is original to the tractor.

With all due respect, I would play it safe. I would not short to ground any wire without knowing where the wire goes.
One wire will go to both coils. The other wire will come from under the flywheel.
If you shorted the charging wires to ground, you could damage the charging coils.
It is easy to remove the flywheel cover.

If it is original, it will be a M18. Electronic ignition. I'm confused though as I would expect more that 2 wires to the engine. 2 charge wire that are AC and not polarity sensitive. And a ground for stopping the engine.

I',m assuming, (yes I know) that not having a coil as stated means no 'normal' coil for a battery operated points/coil system. But there is an ignition coil and module under the flywheel.

Once it's verified to be a M18, there are several wiring diagrams online that will clear it up quickly.

Regulator/rectifier is mounted to the engine so there's only a "charge" wire and a "kill" wire?

Could be. Smaller makers often by 'package' engines from the engine maker rather than providing there own components.

Not true, mine had a K361 which is not the same as an M18.

The poster says he has Power King 1618. The internet says a Power King 1618 can have a M18 Kohler.

18HP horizontally-opposed 2 cylinder Kohler engine M18 power King tractor possibly a 1988.

Harness is from Mission Mfg. they said it was for the original 1618 Power king. M18 Kohler twin cylinder opposed.

Did you call them and review this with them?
