OK now that you mention it, I may have seen smoke coming out of this box when I first attempted to start it before creating this post. 
 

To confirm, how would I have put 12 volts to this? 

The black wire going up behind the fuel pump. show us where that leads to. Lets make sure what kind of ignition it has The engine may have been changed.

That Red wire hooked to the condenser shouldn't be there, If that has power to it ( + ) you just fried ( shorted out ) everything...

Where is the coil located on the K301S-47147B engine? 

This engine originally had magneto ignition with points and condenser.

The coil at the flywheel is self-powered so no battery power required. If the coil gets any battery power it will burn up.

The ignition switch (M) terminal grounds the coil to shut it OFF using the single wire to the points.

 

If the red wire goes to the ignition switch it should be to the (M) terminal.

Pulled off the shrouds but still can’t trace where this little black (oversprayed red, blue arrow) wire goes other than it looks to run with the spark plug wire then terminates somewhere behind the flywheel

OK you still have the trigger ignition. If the  little wire from the switch that goes under the fly wheel got power from the switch     
(OK — touching test light from B+ on battery now shows test light on at ignition/starter and ignition/magneto ) It's fried, That switch shouldn't have put power on that little wire at the switch unless the switch has an internal short which could explain the pop you heard.

Plan of action moving forward? 

[squonk 38,986]

I would install an internally resisted automotive coil (Napa IC14 or equivalent) a switch for battery ignition ( Cole Hersee 95521-B) and probably a new set of points as you saw smoke come out of the points cover. I am not sure if anything else would need to be done.

I would change over to conventional battery/points ignition. This thread should help:

Do you have a unit like the one in this photo on your engine? There is a great deal of speculation going on about what type of ignition system your engine has, The number on your fan shroud tells us that this is the type of ignition you have but that wouldn't have points and condenser. Since the fan shroud is interchangeable to any Kohler engine we can't be sure from what we are seeing. What does the spark plug wire connect to? Does it run behind the flywheel too?

Ignition switch would need to be replaced with a 103-990, also a solenoid would then be needed. We can walk alongside @BrianKoch to make the simple wiring changes needed. Wiring would end up looking a lot like this.

Negative - I have no unit like that

Spark plug wire runs behind flywheel to rectifier/regulator

Edited May 30, 2022 by BrianKoch

[gwest_ca-(File Mod) 10,512]

Early 1968 production used Kohler K301S-4712B with starter/generator and battery ignition

Late 1968 production used Kohler K301S-47147B with Bendix starter, 10 amp alternator and magneto ignition with points and condenser)

 

The tractor model numbers stayed the same with the engine change.

Sorry to say you probably have damaged the magneto coil. You may be able to buy a new magneto coil or a good used one on .

My suggestion would be to buy an ignition coil (NAPA IC14) ,103-990 ignition switch, Solenoid (NAPA ECH ST53) Kohler points & condenser and a small package of AWG 16 wire. Total cost will be around $ 100.00. If for some reason you don't want to go to NAPA they can cross these numbers at any parts store of your choice. We will give you all the guidance you'll need

How does this shopping cart look? I have AWG 16 wire on hand.

Do I still need a magneto coil?

one or the other,                     I would go with the battery powered ignition.

Going with the battery powered ignition.
 

Will check back in a few days once I receive parts. 

[953 nut 51,899]

One thing I forgot to mention, pick up some Packard Delphi 56 connectors for the wires going to your new ignition switch. These hold tighter than the standard spade female terminals. Any good auto parts store will have them in stock.

[BrianKoch 306]

Update: New parts have arrived. I suppose I’ll need to remove the flywheel in order to remove the old magneto coil. How do I go about this?

You don't have to remove the magneto, just leave it in place. I have written up a plan of attack for you and a wiring diagram. The colors of the wires are not important, just a way of seeing where they go. I placed the wiring diagram side by side so you can see that most of your wiring components stay as is. If you have questions be sure to ask. 

The modifications required to install your new ignition system are very easy to accomplish, we will go step by step.

1, Remove the cables from the battery so we don’t have any sparks flying.

2, Remove the wires going to your present ignition switch and replace the switch with your new one.

3, Locate the solenoid where it is accessible and will have a good ground to the engine/battery. Connect one of the small terminals to ground with a small jumper wire.

4, Put the #4 cables that went to the old ignition switch on the solenoid, one on each large terminal, doesn’t matter which one. On the large terminal that will be connected to the battery add a 30 Amp fuse holder that will go to the “B” terminal on the ignition switch.

5, Move the green wire that comes from the voltage regulator from the battery post to the “R” terminal of your new ignition switch.

6, Connect the “S” terminal of the ignition switch to the ungrounded small terminal of the solenoid.

7, Run the wire presently going to the battery from the cigarette lighter/lights to the “A” terminal of your ignition switch and include a 15 or 20 Amp fuse holder.

8, Mount your ignition coil and run a wire from the “I” terminal of the ignition switch to the “+” terminal of the coil.

9, Install your points and condenser gapping the points to .020” maximum opening. The points and condenser will attach to the “-“ terminal of the ignition coil.

10, Now you have five wires connected to the ignition switch; two #4 cables, a ground and the ”S” wire connected to the solenoid; the ignition coil, points and condenser connected. One of the #4 wires is already connected to the starter so all that is left to do is connect the battery cables, start the engine and enjoy the ride.

Question: Where would be an appropriate location to mount the new solenoid? 

[953 nut 51,899]

I would mount the solenoid to the area just below fuel tank close to the battery and engine. Guess your new cables are long enough to reach there.

[BrianKoch 306]

How about here on the flywheel cover? 

[953 nut 51,899]

I have seen them mounted there too, should work well.
