My Pinball Playfield Swap - Stargate - All Electronics Done!
Buddabing:
One coat of wax is done. I don't really see much difference between the parts of the playfield that were waxed and the ones that weren't. They're both super-shiny and beautiful.
I'll probably do two more coats and call it quits.
Buddabing:
2nd coat of wax done. I see zero difference between the waxed and unwaxed surfaces. It's possible that the clearcoat is so smooth that wax will not stick. So I'm done waxing.
Buddabing:
The pyramid is now fixed!
So I reassembled everything and played a test game. The pyramid worked correctly. There were four flaky light sockets which would work if you wiggled the light bulb in them but over time would quit working. So I replaced those from my spare wiring harness.
The slam switch was wired wrong, fixed.
The pendulum tilt switch was not wired, fixed.
During my test game, the VUKs would not kick the ball up correctly. The ball would hit the bottom of the ball guide and bounce down back into the VUK. I adjusted the left VUK and it works correctly now. The right VUK still doesn't kick the ball out about half the time.
The left slingshot kicker sometimes kicks two or three times when a ball hits one of the two switches on it. I've adjusted that switch multiple times, but eventually it still goes back to the semi-machine gunning. It may be time to replace that switch.
The Sarcophagus has an unusual semi-rollover switch. The ball shouldn't roll all the way over the switch, the end of the switch sticks up in the air instead of going back under the playfield. If the switch is not bent at the correct angle, the ball will either roll over the switch, causing it to be blocked between the sarcophagus kicker and the switch, or else will rest against the switch out of range of the kicker. So I've been trying to get that wire bent at exactly the right angle.
Waxing the playfield may have been a mistake. There is wax in some of the hard to reach areas now which will be difficult to get out. My mirror glazed pinballs have wax on them now which makes them not perfectly round. I have two sets of those pinballs, so once the wax is cleaned up I'll use those.
The biggest problem with the machine now is the playfield GI. I was hoping the problem was just the fuse, but the fuse is good. The "T" relay which can also cause the GI to fail is also good. Today I'm going to do some more testing.
Buddabing:
The GI works now!!!!
I stupidly checked the GI fuse in-game instead of removing it. When in-game, it checked out, but when out of the game, it failed. The ohmmeter registered maybe 500 ohms, which is small enough to pass a continuity test.
I replaced it (7.5 amps) with an automotive 10 amp fuse temporarily.
I have not worked on the VUKs yet.
Buddabing:
The right VUK works perfectly now. There was a wire obstructing it.
The left VUK works part of the time, which can be annoying.
Now that the right VUK works, the game is playable. So I put on the glass and played a real game for the first time since February.
The left flipper still won't stay adjusted. I tightened that thing up pretty good but it won't stay. I'll try again, this time adding more force.
The outhole switch seems to be bouncing. Sometimes, when I have three balls in play and one drains, it'll go back to one-ball mode. Or I'll have two in play, one drains, and I'll get end-of-ball. This doesn't happen all the time. So the outhole switch may need some adjusting.
I also bought some 7.5 amp automotive fuses and installed one instead of the temporary 10 amp fuse.
