It will not weld on AC.

So we don't get this wrong (some meters read differently).
If you touch the two probes together the meter reading reads 0 (zero or some around 0.5 half Ohm).

And OL you are getting no reading in the test I asked.

I interpret OL as an open line bad connection.
Again when checking resistance never under power.

More than likely a bad wiper connection in one of the rotary switches.


leave one probe lead on one terminal and start probing back of the other terminal then next wire connection. looking for a reading.

I don't know the exact resistance it should be across the two terminals so lets say it should be less than 10 ohms, now find out why its not.

Yes my meters read 0.
And OL means bad.
The motor was off.

We tried two different meters. Both read the same.

All those items also make the Generator power.
So load testing the generator pretty much tells me all those items are working

its from the welding coil to the two terminals
switch set on AC removes SR1 and DC-Z from the circuit.

hard to tell switch on "wire" may remove AC-Z from the circuit. likely AC-z not an issue also.

There just maybe a fuse screwed onto the back of one of the terminals, or some idiot did not assemble the terminal insulators properly with the wire, breaking the circuit (seen it done).

OK, then you have an open circuit. (bad connection)
you need a reading of less than say 10 ohms, in that completed circuit.
