Pinball mechanical problems

My recommendation is just to start at the beginning of marvin3m's EM rehab process and do all of it. It will very likely fix all of these issues.

Yeah, I've been impatient and trying to just jump to the obvious problems. Impatience and EM's don't seem to go together.
ChadTower:
Impatience and shopping out anything is a bad combination. A good shop job heads off 90% of problems before you even find them.
Chris:
I finally found the source of the 10 point short... one of the stand-up switches behind the rubber below the flippers was shorting. I also found a stuck EOS switch on the ball return kickback coil so it's working now. Theoretically it's pretty playable now at least for 1 player.
Chris:
I've also fixed the problem with the captive ball spinner having two rewards reversed... I just desoldered and swapped the wires for the two rewards from the schematic.
My biggest remaining mechanical problems are:
* In a 3 or 4 player game, the game gets stuck on player 2 and rarely moves to player 3. In a two-player game things progress normally. Very odd.
* Player 2's thousands reel wont reset. It has two switches stuck open, but when I adjust them "correctly" the coil energizes constantly when power is on.
* One of the stand up switches doesn't work. FIXED
* Still need to repair the mangled coin switches.I also have a lot of lamp sockets that need rehabilitating, and next time I order anything I'm going to get replacement coil sleeves. At this point, though, it's playable as a single-player game on free play. Thank goodness for Marvin3M!

Check the "Player Unit Disc" and the "Ball Count Unit Disc" out carefully. They may need cleaning or adjusting as well. Something may not be contacting correctly there to change players in four player mode.

Check the 1-2 Reset Relay and make sure it's N.O. after reset on the corresponding switch.

Not much to those. Maybe ohm the wiring and look for a bad connection or break.
Of course these are just starter points on troubleshooting. Ya still might have to trace things out one way or another from those points to find the culprit switch or cantact that is causing the problem.
Typical EM stuff..... you either love em' or hate em'. ;)
P.S. I'm assuming you have both the manual and schematic from IPBD online right?
