Sorry for delays. Work gets in the way of everything.
NAPA solenoid part number - ST81SB

I even tried - STH404 originally but felt ST81SB was a cleaner
mount and set up. Same response with both.

can you mark up your earlier schematic to reflect the wiring around st81 of your latest photo? Also, what is the kill switch? How about pictures of it?

Later: I marked it up according to my understanding of your picture & written description. If this is the way you have it wired, then it is nearly OK. Needs the ammeter change (back to the way you had it before hashed out). Being the 1-wire alternator, it only needs the one wire I marked & dump the small black from ign sw.

Now the BIGGIE! Wrong solenoid! You need ST-542.

I still need some info on the "kill switch", which I expect is a ballast resistor.

Then you should be all set to crank it up.

Success as far as wiring the starter goes. All I did was swap in the new ST-542 solenoid you suggested and the starter worked as it should!
I can't tell you exactly how I have the ammeter wired - I paid attention but can't remember! I think it's the way I had it originally drawn. If it isn't like your diagram I'll change the ammeter to the way you have it. But if it works, does it really matter?

Also, we have the red wire from the ammeter going directly to the post on the STARTER, because the copper solenoid post isn't long enough to accommodate 3 wires (see your diagram) So, once again, But if it works, does it really matter? My concerns are is it charging the battery properly the way I have it wired or must I make it like yours? AND, how do I wire up headlights and work lights with this set up?

The ring gear is bad, so we didn't want to beat the new bendix up too bad so we drug the Funk with the other tractor to bump start it. But it wouldn't start because the plug wires were wrong at the distributor. The firing order was correct but we had to move them back counter clockwise one. Then she ran fine after warming up and doing a little brush hogging for about 20 - 30 minutes. But then she died as if she ran out of gas. I think there was enough gas but I put 5 gallons in anyway. Ran for less than 5 min then died again. Restarted and ran only one to three minutes several times, enough so I could get it put away. So, a new problem. Other problems are the 3 point won't lift, and the pto won't shift in and out easily. I'll start new threads if I can't figure it all out.

Thanks again JMOR!!!!

Quoting Removed, click Modern View to seeRed starter to ammeter vs solenoid to ammeter does not matter.........it is just battery to ammeter connection any way you do it.

If you don't connect the wires on the other terminal (left on drawing), where two are on load side & ONLY one (battery) to other side, then your ammeter will register only charging current & never show any load current. The load current would come directly from battery via starter terminal & never pass through ammeter. Still charge OK, though.
For lights, pick up power at the left ammeter terminal, go to switch & from switch to lights. Stick a fuse inline if you like.

As for the assistance, you are very welcome!

I"ll try post pic of kill switch. All I know is it"s inline between key switch and coil - as in wiring diagram. Up is "on". Not that that matters.

I do know from the guy that"s helping me that we have had spark at the points.

Today"s the day: I picked up the new ST-542 solenoid last night and will install it and wire it up as in your diagram. Yes, your finished diagram at the solenoid / starter is primarily how I tried to wire it, but when it didn"t work I tried different things. I can"t remember how the ammeter and key switch were originally wired but I can go back and look at original pictures I took. I believe it was as you diagramed.

Wish me Luck!
I"ll keep you posted.
And many THANKS!
