Castle door switch (resized).jpg

#1 8 days ago

Good afternoon,
My awesome original MM has developed a strange issue. When you turn the game on and start a new game everything appears to be working. The odd thing that developed it that the first 5-7 games the ball lock door does not register at all. The castle draw bridge goes down and gate goes up leaving for one more ball to destroy the castle but it goes in and the solenoid ejects it out the left side. The other is the small castle door lock. When through the door the animation of ball smashing through shows, then ball two shows other ball smashing through and on third the awesome animation plays starting Multi-ball. Normally you get three balls though the door and get multi-ball started after the cool graphic on DMD. (looks awesome with my ColorDMD). Until the game warms up (seriously I am in freakin' Arizona, nothing is cold these two features do not work at all and them magically it starts working and works every time in every game until you are done playing. I just had a thought to see if once it warms up I shut down and power back up and see if it works instantly.

Has anyone ever had this issue. It drives me nuts because I do a layup on the dragon ramp and then nail the ball lock shot and poof ejects with no credit.

UPDATE: The switch stopped working totally so I removed the two mounting screws to get a better look. It appears the green white stripe was soldered to the outer leg and cut and re-soldered to the center switch post. See picture. We are hosting Thanksgiving tomorrow and hope someone can look at their switch wiring. REMEMBER mine is the original Williams game so I am not sure how other versions are wired.

Unplug your color DMD and play it blind. Then see if it works or not. If it then works the 12 volts is the culprit.

Thanks so much for quick response.
Did you take a look at the switch picture? I would like to replace the switch since its already out. where should the Green wire with white stripe be soldered. This may have been an attempt to prolong the switches life before it died.

Just now. It is wired right.

Put a meter on it. Bad switch or broken wire elsewhere from switch to switch to CPU.

The tiny green nub of a wire shouldn't be there. Maybe a mistake from the past.

You can compare to other switches in your game. If wired right they are all wired the same.

White wire to a lug with black end of the diode. Green wire to a lug. Silver band end of the diode to a lug. Stripes may be different colors but the base colors are the same on every switch.

Well the patient has been prepped for a new switch. Wish me luck on a successful Switchectomy!

Sorry for the delay, I was too busy locking balls! YES!!! The switch replacement worked perfectly. Thanks for the assistance. Tomorrow it will be the hit of the party.
