My 2003 FXD recently began failing to stay connected when starting. When the starter button was pushed, the starter assy would engage for a short time - then quit, with a loud 'crannkk' noise. I thought it might be the solenoid clutch, for the normal failure mode of the jackshaft is a total disconnect. I replaced the clutch with a Harley kit and cleaned the solenoid surfaces, the starter motor was healthy and turning. It continues to do the same thing. Could it be the jackshaft - grabbing, but only partially? Has anyone dealt with this before? Thanks in advance for any input you may have.
