Two volts at A and F posts, what's wrong?

I'm gonna sit this one out

It all seems to be wired correctly, though my ignition switch is laid out differently than the one in the diagram, and looks like it was hacked in to the tractor.

I can't tell who made my VR, it isn't marked, except for Made In USA on the metal tab that's part of the rubber insulator mount.

When I did your test, I took all the measurements at the battery, like you said to. I just took additional ones right at the SG, to eliminate the wires from the question.

I've just removed the gas tank to get a closer look, and though my ignition switch is different than the one in the diagram, it has IGN, BAT, and ST terminals, and they all have the right wires on them.

The only weird thing I see with the wiring is that my charge gauge has the two wires hooked up to what on the face of the gauge is the positive side, and the single wire, from the solenoid, hooked up to what on the FACE of the gauge is the negative side. I'm not sure if they switch sides internally. There are no +/- marks on the side with the terminals, just on the face.

There's also one smaller terminal on my charge gauge that says GRD, ground, with nothing hooked to it. That terminal isn't shown in your diagram.

Lets have a picture(s), in detail, of the Amp Gauge, Ignition Switch, and the V/R.

Would I be correct in assuming the S/G is a Delco used by Cub Cadet...???

[nothercrash]

I don't know if it's the Delco SG. It certainly looks exactly like the rest, the case is the same, but it's not marked.

This tractor used to do some work, before it started having one issue after another. The last pic is it dragging 12-14" oak logs.

Thanks for the Pictures. I was hoping for a better picture(s) of the V/R to determine the make of the V/R and if it it wired correctly.

(A) You have a Non-Cub Cadet Amp Gauge. It looks like the "small" terminal was used to back light the gauge. Make sure it is wired as follows:
+ = Red/White Wire
- = Green and Gray Wires

(B) You have a Non-Cub Cadet Ignition switch. Make sure it is wired as follows:

B = Green Wire
I = Black & Blue Wires
S = Orange Wire.

I have taken the 1x8/9 Wiring Diagram and stripped it down to the Charging Circuit only. Make sure that the tractor is wired as per this diagram, that each wire is ohmed out and there is no lose. That each wire's terminal ends are clean and tight to each connecting terminal.

In addition...........I see a lot of rust and corrosion. I would highly suggest, that each wire end and connecting terminal be cleaned up to bright metal, studs, nuts, spade connections, and eyelet connections. Use sandpaper, steel wool, or Dremel Tool (to mention a few) to ensure each wire and mating surface is clean & tight.

Re-test the Charging Circuit and report back.
