My Pinball Playfield Swap - Stargate - All Electronics Done!
Santoro:
Wow, you learn something new every day. Dishwasher!?!
What keeps water from seeping into the wires and causing corrosion?
BTW Budda, awesome. I want to get into Pins one day.
Buddabing:
Well, the wires are insulated. No corrosion is possible in insulated wires.
There are two problems with the dishwasher approach. One is that some of my leaf switches got broken. The other is that water got trapped inside some of the light sockets.
If I had to do it again I would unsolder all my leaf switches. There were not that many of them.
However, I would keep the light sockets soldered on, except this time I would remove all light bulbs. The sockets should be dry after the dishwasher is run. If not, just shake them out, maybe stick a paper towel down there to get any excess moisture out, and let the harness dry for a couple of days.
WARNING: Pinball is expensive!
Wade:
Sorry to hear about the leaf switch, surely fixing that is much easier than cleaning that whole thing by hand. The water in the sockets is pretty standard. Light sockets, under chips (on PCB's), etc. usually hold some water after I dishwash them. I usually just shake them out and let them air dry a couple of days, and sometimes I blow them off with my air compressor.
Looking good!!

I spent this weekend working mostly on the wiring.
A light bulb went on in my head and now I understand why the wires in the wiring harnesses are striped the way they are. There are patterns of stripes, one with one color and two with another color. These match codes which are given in the manual for the various signals. So, black-brown-brown is code 011, red-orange-orange is 233, etc.
This new knowledge allowed me to check the locations of all the light sockets that needed to be soldered to the ground braid. Several of them were wrong and I would have had to unsolder them, correct them, and resolder them. There are about 17 of these soldered-in light sockets. I've now soldered those onto the ground braid.
The solenoid wires have the same color scheme as the light sockets so I am now working on those. There are a whole ton of solenoids in this machine!
I've also run the cabinet wiring harnesses through the dishwasher and they are now drying for the next couple of days.
I cleaned up the transformers and installed them back into the cabinet.
I spent some time cleaning up the metal side rails. After posting on RGP, the general consensus was that sandpaper should be used, with progressively finer grit. That seemed to work okay.
I was able to piece together the two leaf switches that were broken. I may not have to replace those after all.
No pictures, nothing was really changed appearance-wise.
Buddabing:
The wiring is done. I've flipped the playfield over again on the rotisserie.
I moved the rotisserie so that is is right next to the cabinet. Then I tried to plug in the cables. Fortunately, there was just enough slack for all the cables to be plugged into the boards in the head. Yay!
I held my breath for the moment of truth, power-up. No magic smoke was released! The machine came up! Success!
I went through the self tests. All the lights work, my insight into the lighting codes worked out well!
Most of the coils work, but not all. Most of the switches work, but not all.
Next up is debugging the switches and coils. Then I have to put the ramps back on, they have opto switches in them.
I am very close to completion.
