1968 Wheelhorse Raider 12 with K301 no spark

I have a 1968 Wheelhorse Raider 12. It has a K301 12 horsepower Kohler engine.
It has no spark, and no voltage going to the points!
So how do I diagnose it?

It has an ignition switch with 5 contacts. How can I tell if it's good or bad?
And could it be the voltage regulator? How can I tell if it's good or bad?

It apparently has no solenoid.

I'd appreciate some direction on this.

The ignition switch should have one terminal with a b on it for battery. Often this terminal is brass. Does this terminal have voltage to it?

The battery cable goes directly to the ignition switch, and another cable goes from the ignition switch to the starter. There is no solenoid.
It's a little different from most lawn tractors.

The starter engages, and the engine turns over.

But there is no power, on the wire that goes from the ignition switch to the points.
Shouldn't the wire that goes to the points have 12V?

Ok, on a system like that, you should have a wire going from the starter to the coil positive, so that when you crank the engine, the coil positive is getting full 12 volts. Then, there should be another wire going from the ignition terminal on the switch to a resistor which reduces it to 6 volts and then goes also to the positive side of the coil. The negative side of the coil should go to the points. First, find out if you have power to the positive side of the coil. If so, and still not at the points, then you probably have a bad coil.

Okay. I'll have to figure out which wire that is?
It has no external coil. The coil is inside the engine.
And there are 2 wires that go to the internal coil. But I don't know which is + and which is -
