Do you have a schematic diagram? You say you're new to EM repair, but what's your general level of repair and troubleshooting ability? The circuit for decrementing the ball count unit should be fairly easy to trace out with a schematic. Pinball Resource (pbresource.com) would likely have one for your game if you don't have one.
You say this happened after lifting the playfield, or do you mean it only does this only when the playfield is lifted?
A start would be to pull and reseat all the Jones plug connectors going to the motor board from the playfield, and the ones going to the light box (head). Do this with the game unplugged from the power source.

Use two hands and wiggle them loose grasping the connector on each end.

Yes, it does pull out. As I said, slowly wiggle it off with firm and steady pressure. They can break, so be careful.

Quoted from pacmanretro:

With no power to machine, use your multi meter set to continuity (or resistance), put one lead on each of the 2 switch blade tabs (where the wires are soldered). Check that the switch is open and when you use rollover the switch closes. Should be easy enough to check on that one.

You may not get an accurate read on the continuity unless one of the wires is desoldered from the switch. It's the same with checking a fuse in circuit. You have to pull at least one end of the fuse out of the holder.
