I can always tell the level of enjoyment I get working on a machine by how much it consumes my free time. Funhouse has been consuming a lot of my free time over the last few weeks which means progress has been good. So I’m back again with the third update. In this update, I’ll be focusing on the playfield area (and assemblies) in the middle stretch of the playfield. This includes the right scoop, pop bumpers and left upper flipper. There are various plastics and metal posts that will need to be removed and cleaned. There is also a ramp that runs below the playfield connecting other assemblies to the scoop which I’ll remove and clean too.

There is rarely a dull moment in owning pinball machines as there’s always something that needs fixing or adjusting. A small fault was recently noticed in my Pinbot machine, where the left out lane switch would not register when the ball rolled over it. It was a quick and easy fix, but wanted to cover it for future readers anyway. First up, I put the game into test mode and activated the switch with my finger – as expected, the switch did not register. I then manually tested other switches around the playfield. Interestingly, the left in lane switch also did not register. Other switches were fine though. So two were switches (right beside each other) were misbehaving.

At the end of my previous update, I was really close to having the repair work on Playball complete. I haven’t had as much time as I would like lately to look at the machine, so it dragged on a little longer than I had hoped. The time has come though to get the machine running 100% and returned to its owner. I had two issues on my plate to deal with. The first was the third base lamp occasionally not lighting up when it should and the second was the score motor continuing to run intermittently during play. The third base issue turned out to be a dirty shoe on the hit unit. I had somehow missed cleaning it along with the others in my last update. Nice and simple. That just leaves the dreaded score motor.

Playball has come along nicely since it was first dropped off for repair and it’s a satisfying feeling each time a forward step is made. Getting old machines back into a fully working state is what I love most about this hobby. I finished up my last update with an initial look at the three man on base relays. These are the interlock style relays, which have 2 coils to toggle its switches between state. In Playball, these control if a man is on the base or not. The specific problem I’m looking into is why the man on base relays do not reset as part of the game reset sequence. Currently, their state is carried between games.

Since the playfield swap, Pinbot has been running really well and been a joy to play. Recently though, an error appeared when the machine was switched on. The game detected there were errors with 3 of the switches, and reported them during the start up sequence. They are reported as “switch adjust” errors and the knocker fires off 4 – 5 times for each one. It’s an obnoxious sound, and certainly gets your attention that there is an error. The game reported that there was an error with switches 35, 36 and 37.
