My sears 12 has a red idiot light on the dash
It's sole purpose in life is to tell me when it is not charging correctly

At Daniels, it was on the whole second day.
Seems mundane enough but the problem was actually much bigger than I realized

I am going to give you all the clues that I had. You have the advantage of knowing that they are all associated

Shortly after the morning first pass on Saturday, the belt began to slip when I was trying to start the tractor

The next time I shut the machine down, it would not restart without the jumper pack.

After I got it restarted the red charge light remained on.

Battery seemed to take a charge while the jumper pack was connected but would go dead just sitting there with the key off.

By the end of the day the starter generator would turn over in the run or start position.

____________________________________

Got the machine in the garage tonight and the first thing I noticed was the generator was wobbling
After I got the tinwork off the tractor I discovered that the back end generator bold was missing .
I fix that and retentioned the belt. Still was not charging. Still was trying to start the tractor in the run position.

Thinking I had a problem with my ignition switch, I took it out, took it apart, and cleaned it all up. Tractor still tried to start in run position. By disconnecting wires one of the time I determined it was a wire that went down to the regulator.

And that is when I found the root of the problemimage.jpeg

Anyone else see it?

Looks like the regulator cover is rusted to pieces, causing a short?

I retrieved the bolt and called it a lot of names. (Who found the bolt in that pic?)
Put the jumper pack on, And the tractor still tried to start in the run position

Took regulator out and found contacts welded.
Broke loose, and cleaned up the contacts.

Tractor stop trying to start itself in the run position but after it started, would still not charge.
( I am beginning to get tired of this little red light )

I took the regulator back out and really studied it
In this picture there should be a wire between the two circled pinsimage.png

After checking the rest of the regulator over and finding nothing else, I went ahead and made a new wire.
I copied it from what was left of the old one.image.jpeg image.jpeg

It now starts when it should and charges when it should.
The lights even work again.

Hopefully tomorrow I can get it all reassembled

Alan, the idiot light wasnt looking for you. In fact, I bet that bolt fell out while Karen was driving LOL.

I had thrown the old scraps away before I thought to take a pic of it.
The new one is pretty close to what was there, just a little bigger.



No one found the bolt in the pic in the first post?

Alan, i'm not sure what Larry is calling a vapor wire but what about a fusible link that was designed to burn out during a short instead of burning the tractor down? Is that the bolt hiding by the terminal at the bottom?

So the bolt fell across the contacts and that caused the wire to burn out? Nice fusible link!

I saw the bolt in the pic.  I have also had starter/gens not charging & found that little wire burnt in-two and simply did as you, solder a heavy wire in, and end of problem.
