Fleetwin – This started happening after I replaced one of the pistons/rods and put everything back together. I had all 4 coil leads grounded via some spark testers.
For what it’s worth how would not having them grounded cause the bendix to disengage?
I have not worked on many of these optical ignition motors, but was careful to take off/replace everything without disturbing components. In fact, I realized the components are relatively simple so was encouraged to see this.
The motor is back outside fogged and covered in our recent snow so I may not be able to retest again until the summer. Sounds like another learning opportunity.
