Hello all.. New member with his first post. I just picked up a 1966 Williams Full House. I am pretty stoked to clean it up and bring it back to life. It seems to be working ok but a little soft on the some of the bumpers.
My main issue is the ball eject doesn't work at all Has anyone had this problem and or repaired this problem?
Thanks in advance for any help

Wow Thanks for the excellent trouble shooting post. I will print off your email and print off the schematic and work my way through your advice
Thanks again
Tom

Thanks Rolf
When the ball is in the kickout slot and I make the switch activate..with power on ...nothing happens except the (control motor?) goes round and round until I shut off the power. I think this is the control motor in the second picture

I would guess that means the coil in that first picture is no good ...correct?

Hey Rolf
So I found the Outhole relay as you said. below the playfield. It is "pulling" to close the contacts when the hole switch is activated....one of the switches is arcing pretty good but it is closing I may clean it up with a little emery cloth

Hey Rolf
I checked all the wires I didn't find any that weren't soldered on. I wiggled all the wires and advanced the ball count unit. Once that was done I started the machine back up and it began operating the ball kick out over and over and over. I shut it down advanced the ball count unit again started it up and it is back to normal not activating ball the kick out.
I have attached a pic can you confirm this is the ball count step up unit

Im an idiot ...Once I posted I now see the label on the unit

Hey Rolf Sorry to have dropped off the topic. I have some pretty bad back issues which is why I have changed my hobby of restoring cars to restoring pinball machines. I have been laid up for the last little bit.
I have not went through your last recommendations and excellent help. I hope to be back on this project next week

Hey Rolf I was able to spend some time digesting where we are at in this troubleshooting process. Man it seemed like I had to review everything to et it straight in my head again.
So here is where I am at.
I believe we have issue BBB ...situation BBB: SCM-5A does not open
My problem is when I start a new game the Control Motor never stops it just continues to go and the "Ball Release Coil" fires steady as well as the Outhole Relay it fires steady as well!
I wish there was a way to post videos so you could see it. I have trouble explaining what is all going on
Thanks for your help as always
Tom

Hey Rolf
Yes
Ball Release coil fires pulsing "pulling -> not pulling -> pulling -> not pulling ... " endlessly

"Outhole-Relay": (State JJJ) "pulling -> not pulling -> pulling ..." endlessly,

I am Canadian so I have my own issues hahaha
