Start off by checking that the plunger can move freely.
Check the connectors are not tarnished
Check that the wire is pushed in on the respective IDC connectors (J130 / J107)
Check Q68 visually - does it look ok ?
1) The plunger moves freely, no resistance at all in the movement up and down.
2) Do you mean the connectors on the Driver board or the connector near the coil? And by tarnished, do you mean burnt or just discoloured?
3) I reseated the connectors on the Driver board and made sure they were pushed in fully.
4) What is Q68?
