First thing is to fine the Motor on the schematic to see what RE’s (Relay) starts it.
It should look like this and the Spanish word for motor is motoro, I think.
One of these SW is staying closed either cos of adjustment of the coil (relay) is not de energising.
What format is your Schematic in, Email able?

PS Clarkson, is that Perth? and welcome to Pinside.

Score reels or Bonus Unit not reading at "zero" position.

Thousands of posts here and on RGP regarding this symptom. Does not matter if Bally, Williams, Gottlieb, Chicago Coin or Playmatic.

There are switches on the score reel units that come out of adjustment. First you tighten the screws holding the switch stacks (screw closest to the contact points first) then adjust the switches for proper operation.

Bonus unit zero is usually a gummed up unit that really does not fully retreat to the home position. More tan likely, the problem is with the score reel assemblies.

You may have checked this already, but sometimes one or more of the coin switches are stuck together causing the motor to keep going...

I've got a Playmatic Speakeasy that I set up recently to work on. It powers up, starts a game, scores most targets, but there is one chime coil that gets locked on and the reel in the back box starts humming away since that too gets locked on.

Also, my flippers don't move. Hmmm..... I have no schematics or anything for this machine, but I'm assuming the fuse on the bottom side of the playfield is for the flippers.... and it tests good.

If anyone has a pdf of the schematics for the Playmatic Speakeasy that would be great, even though it's probably in Spanish.

Also looking for the top arch plastic as mine is badly melted and broken.

IPDB is still broken so I uploaded it to
