It's a 1969 (maybe 70) Kohler 14HP. K321S.

Alternator has 2 wires. There was an old, old regulator bolted to the outside of the tractor grill. Might have been upgraded from original equip with 10A or 15A alternator. Original may have had low Amp output with seperate lighting wires - that setup didn't use a regulator.

I would check to see if there is a ground wire in the loom of the coils that would ground to the block when the loom is installed. If there is, measure voltage on "AC" of meter between block and each ofthe two wires. In this type of wiring, there are two outputs. You can identify this too by checking continuity between each wire and the block. If there is continuity, there is a ground in there.

If there is no ground to the block, the output is solely the two leads.

If that voltage is the 5 volts you mentioned initially, even if measured on "AC" scale of meter, the magnet ring is to blame as there may not be enough magnetism left to induce the voltage and current required to even fully overcome the internal resistance of the wire in the coils.
