What a disaster. The question really is, why after a genny repair the need to remove the VR coil wire? Is there a problem with the genny? I would probably go to the lift that is working and get measurements/tap settings of all fields and resistances( very hard to remember without a print) if you can. I would also test the FPM as well as a guide. Then clean and test the genny commutator and brush set and neutral planes. I think the lift should be slightly faster in the up direction and should be set via series taps however I cant quite remember what these are ie more or less. Trial and error maybe. Also I think HSL speed should be around 50 FPM. Sorry not much else I can remember, so not much help.
