MF 20 Ind wiring

Here I am again guys, asking for advice cause I am stumped....
My Industrial 20 (3cyl Perkins Gas) seems to have a wiring problem that I can't manage to track down. I have traced every wire (except for the light circuit which is unhooked) and replaced damaged wiring so that everything is complete and matches the diagram.
I replaced the ignition switch because the old one pretty much fell apart when I touched it, and replaced the voltage regulator that was pretty well baked. It appears as if the battery moved in the tray (hold down clamp long gone when I got it) and pinched a wire coming from the regulator, causing a short, and heating which cooked alll the wiring within 2 inches of the regulator, all of which I replaced.
I have a good battery installed and am getting 13+ volts from positive to negative and positive to engine block. I have 13+ volts to the starter wire. However, I have no voltage to the ignition switch, and obviously, none coming out of the ignition to fire the solenoid.
I have not resorted to jumping the solenoid straight from the starter wire for fear of damaging something further, but I am about to that point.
Obviously, I am missing something, but can't seem to put my finger on it.
Any help or advice would be greatly appreciated.
Thanks,
Jess

I think you need to run a wire from the starter battery connection to the switch terminal Bat. then a wire from switch starter terminal to solenoid.

Phil, that seems like it would work to me, but do i disconnect the wire that is currently on the "Bat" terminal (It comes from the voltage regulator) or do I leave it there and add the new wire to it?

I'm not sure just how your regulator is wired so I can't help you on that. I use the single wire alternators on all my equipment. I hate external regulators.

I'm quickly beginning to hate them myself!! I think I will remove the wire from the voltage regulator and add one straight from the starter battery terminal. Your suggestion got me thinking...Why does the voltage regulator need to be in the start circuit anyway? If the engine isn't turning, the alternator has no output, thus the regulator has nothing to regulate, right?? Just a thought, but I'm gonna try it. Whats the worst that could happen, right?
Thanks
