After installing a new three pronged cord I started to work on a Gottlieb World Fair.
Funny, I would hear that sound the pin makes when you turn on the power, now it's just dead quiet till I hit the start relay.
The start button did work. If I remember, I filed a relay switch and now it doesn’t work.
I can manually engage the start relay, the hold relay energizes and the control bank resets.
The main problem is no power to the coils/bumpers/rollovers/slings on the playfield.
The playfield and backbox lights do work.
l did engage a relay and the rollovers were keeping score, but I can’t recreate what I did.
I have the TOP Vol. 1 DVD and apparently, the 0-9 unit on the backbox should “always” be moving.
My unit does not move at all. Can that be the problem?
I cleaned and lubed the rivets and that arm that usually freezes up does move.
The fuses are good, the score reels can reset to zero and I have the schematic.
Silly question: does this pin need 5 balls in the trough to run?
Does the score motor look to be in the right position?
I also included a picture of the credit unit.
Any suggestions what could be wrong?
