If I recall, that is a generic key and can be had at tractor supply.
Don't believe the switch for the headlamps should be grounded? It only switches B+????

Well I found the key. It had fallen out of the ignition and I had then accidentally stepped on it mashing it into the ground. I am lucky to have found it really. The ring it was on was just a small copper wire my Dad stuck around it. I went out and bought a nice new FORD key chain for it and I doubt I will be having any issues losing the key again.

Is there anywhere you can buy the original tires to these tractors with the original tread? My front tire has a slow leak. It goes down in 3 weeks. I would like to just buy two new front tires.

Somewhere recently a distributor was remaking the Firestones in Viet Nam, cost $100 apiece, not sure if front or rear.  Leak might just be the valve stem core, could try some water in the hole look for bubbles.  If so unscrew the core take it to a gas station they could match up the core buy the whole valve stem just a couple bucks if so an easy fix.

Well this was a pretty exciting day in the life of Paul Miner small engine mechanic, hack, trial & error specialist.  Finally got the lights to work. Wow what a mind bender that was of testing wires, loosening wires, tightening them back up to make sure the connection was good. I did end up buying a new light switch, plus all new light bulbs but once I replaced the switch I found the older front bulbs actually worked and were much brighter then the ones I had replaced. So I put the old ones in but one broke on the way in. Ford didn't leave much space between the gas tank and the front lights to work with.  Also the connection up there was very loose. I could turn the lights on and off simply by pressing a screwdriver up against them. I had to readjust the plates that screw the light assembly box up against the front of the tractor and tight. When tight up against metal they worked.

I also had to unscrew the voltage regulator and pulled that back and I don't know if a connection into that was loose or something but once that was off and then back on again it seemed things worked a little better as well.

I got it done. I wasn't going to take out the gas tank.

 

does anyone have a detailed schematic of the PTO Switch wiring and the light indicating the PTO is on. Its pretty obvious when the PTO is on and off but I noticed tonight while it was all apart that the wire to the light indicating it was on was disconnected. I couldn't figure out where to connect it.  I have a few wiring diagrams but they do not go into much more detail. It just shows the PTO switch.

Ok well that's it for today. I am sure glad to get the lights working and I hope I can find a brighter bulb to replace the broken one. I think it might be similar to snowmobile bulb. Pretty bright.

I didn't know these even came with a light on the PTO circuit. Glad you got the others working. Sounds like you may have been battling an intermittent ground on things.

Same thought went thru my mind. I'm wondering if he doesn't need to do what one of the sears needed (they, too, used a chassis ground thru the grill and plate)
I added a wire from the frame (random bolt) to the bolt where the light ground ties in. Made a big difference as before, the lights would flash each bump I hit.

Yup, mine has one as well. It's a neat little feature.

Well huge snow storm coming our way I was all excited to blow some snow now I went out and good old blue started right up and is purring lie a kitten but the  PTO will not even activate now.  No snow blowing till this is fixed. I think it must have to do with the light wire being disconnected? I don't think any of the other wiring got touched that would impact the PTO.  That is the only thing I can think of. The PTO and blower worked a few weeks ago when I tested her.  I really hope I can figure this out before the storm hits.

 

Any ideas?

This is the nearest thing I have to an electrical diagram. Does one exist of the PTO switch only? This is my weakest link honestly. This electrical stuff is greek to me. I'd be better off baking a beef stroganoff.  

BUT I WILL PERSERVE AND GET THIS DONE!

Somehow. I will fix it.

I looked at your attachments and the one for the 10,etc HP is for 72 and newer tractors. The other one does not even show the PTO. Just out of curiosity, how many spots do you have on the back of the PTO switch for wires to hook in?

Could possibly be a bit of corrosion in the switch.
