Do you know what those 2 areThere are a couple others not marked, but all in all, not many.

Not yet been raining like crazy here. Been trying to read up on all these testing procedures. But definitely will. Borrowed my buddies ohms meter. I think someone swapped the vR out especially after seeing it was missing that surge protector. I'm getting anxious because I want to figure this out. Thank you for your assistance.Did you test that big fat fuse that is next to the A1?
Between T3 and T4 126.77.6 volts there is exactly current. TM says "approximately 8 VDC". 7.6 VDC is what I measure on my good working set.
Measuring 7.6 indicates the "flashing" circuit is working and you have continuity from there to the exciter and the exciter is receiving the voltage.
What voltages and resistances do you get with the other VR tests?
That's good. It indicates the exciter is working, flashing the gen head and the gen head stator is putting out AC voltage.Between T3 and T4 126.7
That's not good.T7 and T8 000
Voltage adjustment test Nothing

YesThat's good. It indicates the exciter is working, flashing the gen head and the gen head stator is putting out AC voltage.
That's not good.
When you did the test did you disconnect wire 156A from the VR and then measure the RESISTANCE between wire 156A and terminal 2 of the VR while rotating the AC Voltage adjust knob?
My mistake there are digits while testingT3
Yes
YesOK, that would indicate a problem with either the wiring from VR terminals 1 & 2 to the voltage adjust potentiometer on the front panel or a problem with the voltage adjust potentiometer itself on the front panel.
Just to re-verity. You measured 126.7 volts AC between VR terminals 3 & 4 with S1 in START. Correct?
My mistake it is giving a reading when I rotate the adjustment knobThat's good. It indicates the exciter is working, flashing the gen head and the gen head stator is putting out AC voltage.
