I currently have this machine in the shop and troubleshooting an issue.

With credit on the machine, a selection is made but the add solenoid in the control center does not engage fully to open the motor control switch.

With the power removed, the plunger moves freely manually with no drag or bind.

If I manually scan the mech via the service switch, the solenoid engages and the mech goes fully into scan mode.

It acts like the solenoid is only receiving a short pulse.

Does this sound like a faulty service switch or contacts in the Electrical Selector?
