The problems started once the machine was moved. Fairly typical problem.
As others have mentioned, refit the jones plugs as a start.
Check the tilt assembly on the front right hand side of the cabinet. There should be a tilt ball and sometimes it can be lodged all the way towards the back of it's assembly. This will tilt the game. Also check the tilt plomb. You can remove the plomb itself until the game is working.
Bumper problem - Going from memory, there are two switches activated when the ball hits the bumper skirt. One fires the coil, the other (end of stroke) completes the circuit to the chimes (or bell) AND the score reel via a relay. This second (EOS) switch may need to be gapped.
