Kohler Command Blowing the fuse and kill wire

[guitarsnlikker]

2003 17hp CV490S-27508 Engine starts and runs fantastic. All original. Engine in a Craftsman LT2000.
With kill wire connected at coil and new fuse, engine will start and run but will blow the fuse every time.
Disconnect kill wire at coil engine starts and runs great too, fuse does not blow. Oddly shutting off key does not kill engine via the fuel solenoid. I have to clamp fuel line. Yet solenoid worked when I pulled it off carb and energized it.
I have followed kill wire from coil to ignition switch and see no abrasions, chaffing, etc. Looks pristine. I opened up the loom and tape.
I have replaced ignition switch to a identical known good switch and fuse still blows.
If I disconnect the 6 pin connector (which kill wire goes into) engine starts and runs, fuse does not blow.
If I disconnect the fuel solenoid fuse still blows.
Mower has a volt meter on the dash (not typical ammeter) not working. Has 0.5ohm resistance. Has to be plugged in for mower to crank.
Today I will by pass the volt meter to see if somehow that is causing the fuse to blow.

Assuming I didn't miss anything on the wire(nick, bare copper etc) what else could it be? Can the coil function great like it does yet still be the culprit?
Open to all ideas. Thank you.

It could be that the ignition switch is the problem.

But is this mower one that just develop or is one that you received doing this? As it can be a wiring issue if it is new to you.

Give the mower model number off the serial number and I see if I can find a wiring schematic for you to troubleshoot with.

Thanks for replying.
I bought the mower with this problem.
The ignition switch all 7 posts tested ok with continuity and I did replace it with a known good. Problem still persisted.

The only way the ignition coil can be blowing fuse is for 12v being applied even monetary. So it someone has done so rewiring the mower. And could be lost of ground at the operator present relay #1.

Here is the wiring schematic. Not as clear as I would like it but that is all in the owners manual.
