Hey guys
Got an old composite where the generator armature went low to ground and we have pulled it and had repaired at a reputable motor shop.
On reinstall the speeds are off up versus down even on inspection and the speeds swing based on load in the car.
We believe the 14 15 contacts are good and have tried adding series field resistance with no changes.
Been thinking about it and thinking about going back and checking RFB feedback circuit, but interested if anyone has any suggestions.
