If no power to the lugs with the contactor switch in the UP position. Then... Here is a diagram of how the coil in K1 is powered while you have the contactor switch in the UP position. The RED path is 24 volts to K1-X. The Green path is ground path to K1-Y. Check for 24 volts and ground...

Do you get power to the lugs when running AND you are holding the contactor switch up?

OK, your test h. result of 22.7 VDC confirms my suspicion that there is an open circuit from VR terminals 5,6 and the static exciter or a burned-out static exciter. Most likely it's a wiring/continuity issue and not the static exciter. Here is the wiring path from VR terminal 5 to F- of the...

The image you posted is not the AC VR Test in the TM. That's a brief cheat sheet without the needed steps and conditions to correctly perform the tests. The table of voltages listed on your sheet are approximately what one would measure IF the set was running, no load and outputting correct AC...

It would ready help if you performed the AC Voltage Regulator test per the TM. It has the expected readings for each test. The 17.4vdc reading you reported indicates to me that you have may have an open circuit between VR terminals 5,6 and the Static exciter.

The VR test procedure is in the generators -24 TM

If the Fuse Mod fuse is good and you don't have power the the outlet then you need to perform the AC Voltage Regulator test. Post up the readings for each test step and we'll guide you from there.
