Started getting vibration felt through to the cab.
Only in the up direction and more pronounced as the car passes halfway and continues to the top floor, is at its worst nearing the top floor. The drive cabinet is also making noise consistent with the vibration.
Definitely ruled out the obvious (roller guides etc) I'm looking toward the drive. Has anyone had this happen? Trying to narrow down between tach/capacitors/scr but any ideas would be helpful. Runs great empty car going down and short floor runs going up but any high speed runs sets up a vibration.
Thanks
