CVT1's control winding resistance (C1-C2) should be 9.6Ω, give or take an ohm. That and its other winding resistances are in TM5-6115-585-34 on page 6-15, which is page 93 in my PDF viewer. The C1-C2 winding is pretty easy to measure, since you have to disconnect the wire from only one...

When you say "Same readings" do you mean that both L0-L1 and L0-L3 go higher when turning the front panel adjustment both higher and lower? If so, that's truly strange. CVT1 has several functions. Its windings that terminate in X1, X2, and X3 supply AC to the diode bridge, which is what...

Check both sides of the 240 to neutral at the main output lugs. That is, L1-L0 and L3-L0, and see when they do as you turn the adjustment knob. Use appropriate caution, of course.

If the voltmeter on the generator shows correct voltage, and shows higher and lower voltage with the front panel adjustment, then yes, I'd suspect the other meter.

Dave, it does sound like the regulator is not doing its job. It supplies current to CVT1 when the generator output voltage needs to be reduced. If it can't supply enough current, the voltage will go up. The more load is put on the generator, the more current the regulator needs to supply. I...
