I came back to edit it. Originally, i thought they were using the original headlight switch location for the ignition switch. The mystery switch in the proofmeter hole must be for headlights which i do not have right now. I traced the wires again and they go to across the top of the engine and then to each side where the headlight should mount. Its strapped to the same wires as the generator. It is a different gauge wire than the black one on the generator. That is the only cobbled up mess on it. I think next weekend when i get back, i will pull the hood completely off. It will allow me to get all the acorns and straw out of there and see all the wires really well. The voltage regulator has ants coming out of it so I think it is probably toast.
I am going to order the parts i know i need tonight (fuel line, carb gasket, oil filler cap etc) and I hope they will be here by next friday and i can actually drive it across the field.
I will get a better pic of the markings on the gen and add it to the album. I cannot get the fuel to completely shutoff with the valve so I guess i will look at getting a replacement fuel shutoff too. It would not be that big of deal if it were not for the pin hole in the fuel line.

i added the gen marking picture to the original album.
It says:

NTP "nash truck parts=local rebuilder"

007 "2007"

12v.

It is completely possible all it is wrong is the regulator or i missed a wire. The black wire in the middle of that picture is the one i pulled down when tracing the mystery switch that should go the headlight. The mystery switch as 3 wires on it-b+, common and ground for the light in the switch. It is one of the rocker type switches with the light in it like a wrecker would have to show you its on.

From what I can see of it, it has the outward appearance of an 8N10001 generator & probably stamped 12v because rebuilder changed out field coils & maybe armature to convert it to 12v. Any indication as to it being a 12v VR?

Its friday so that means i returned home and worked with the tractor today after completing the other chores.

I got my box of parts and have everything installed except the proof meter b/c i wanted to wash the tractor first.

I got the key switch installed and everything seems to be working as it should. I have to remove the mystery headlight switch in the morning and wires and installed new wire to run headlights. It cranked in a half a turn with the new fuel line and carb gaskets. You can turn the throttle really low and it still will idle with that model a sound. The only thing i noticed is if you come down real fast with the throttle, it may hiccup and die sometimes.

I will look at other locations for s/n tomorrow as well

Back to the charging circuit, the voltage regulator is marked 12v. I did not get to go get another today but its pretty rusty and the tractor cuts off with the jump box removed. Will any 12 v voltage relay work?
There is no power to the generator wires. I just found how to test voltage regulator and going to do that in the morning. I have power going into the vr but nothing coming out.

If your generator is, as was the original, the TYPE_A unit, then it must uses a TYPE_A VR. If it is a TYPE_B unit then it must use a TYPE_B VR.

Before doing the charging tests, I took the meter and checked the large termininal to ground. It had only 50 ohms resistance. According to the test procedure i found, if you hook the batt term to the arm terminal at the VR, it should increase in voltage which it did not. It dropped in voltage and the big terminal got warm to the touch. I am going to take it back to the local rebuilder this week and have him go through it.

Its unreal how much oil psi this tractor has. The new gauge they sent me only goes to 60 psi. The old one that did not work was an 80 psi. It will max out the gauge with oil psi at full throttle, even hot.

All the gears work as they should. The clutch may be a little weak but its been a while since i have been on a total mechanical clutch. The left brake works ok. The right brake does not work at all. I will have to check into that. With the new proofmeter installed, it will idle all the way down to around 350 with that model a sound.
Tomorrow is lift day. I bought a psi relief valve to put in. The lift will raise really fast until it gets the weight of the bushhog on it and it stops. Hopefully, the relief valve will fix it but I will look in there for leaks tomorrow.

My s/n is 8n432061 with stars on each end. I did look at that but it got dark before i made it to the other locations to look.
