Quoted from jlbintn:

So, the adjustments are all related to the flippers? I'm trying to be sure I understand which switches need to be adjusted so the lock catches and holds the flippers closed.

OP

Quoted from jlbintn:

Got the zipper switch adjusted, it closes properly, only thing that reopens the flippers is hitting that mushroom again. Tilting the machine, ball drain down the out-hole or hitting the other two mushrooms does not open them. To avoid the coil getting overheated, I must tap that mushroom. Even powering off the machine does not cause them to reopen.
For the close flipper solenoid EOS switch, when it goes back to the open position, should the two leaf blades on the bottom (as per sizteves photo) still be in contact?
Some other symptoms, maybe related, maybe not:
The 1000 score relay sticks from time to time. The 10 score relay sticks on any hit that would score 10 points. I have to open it with a business card to keep it from burning up.
The only commonality is that all of this started after I had the playfield up to rebuild the flippers.
On the relay coils, is there an acceptable equivalent for the G-30-1500?

First picture is open, second is closed
Edit to add:
noticed while testing, if I do not hit one of the mushroom bumpers (Odin, Wotan), hitting the blue mushroom (while flippers are closed) does nothing. I hit one of the other two mushrooms (doesn't matter which) then hit the blue mushroom, the flippers open.
Upon further review: the buzzing from the zipper's coil is because it is attempting to open after a drain or hit on Odin/Wotan. So, it is trying to open

OP

Quoted from jlbintn:

Looking at the springs in the pictures provided, I see what you are suggesting. Any suggestions on a replacement, primarily where I could fine one? Anybody know the part number for that spring?

OP

Quoted from jlbintn:

For the most part, it's working fine. The spring wasn't the only issue I eventually dealt with, the coil was a bit weak so I replaced it when the spring arrived.
Question.
What would cause the armature to stick to the coil after the flippers open? Doesn't do it all of the time, but pretty sure it's not (small) spring related. I have to push it off, and by push I mean not much, as there is barely any resistance, but there is some resistance there. As a result, it takes a couple of attempts on the mushroom to break it free before it will close again.
Measured the close coil on the zipper, it's reading 8.5 - 9 ohms, so good there. I cleaned up the entire unit - it was a greasy mess. Installed new nyliners as well.
Anyway, progressing nicely and it is, basically playable now (again)

OP

Quoted from jlbintn:

Definitely magnetized, just enough too. I don't know that I want to mess with that spring, until I can secure a replacement. Right now, it's down to having to hit the mushroom once to pull that armature up. That's a quirk I can live with until another solution comes along.

OP

Quoted from jlbintn:

Some shots. Odin lane is the worst of the wear on the playfield. Would love to find a stencil. Or, color me crazy, if I could find a playfield I might just roll with a swap.
Edit to add:
The playfield was pretty dirty when I got the game. Fifty years old, no surprises obviously. We tried to clean it up as best we could, but some of the dark marks in areas were just not coming up so we did what we could and then invested in a playfield protector. Every once in a while we have issues with the buttons, specifically the 10 point buttons getting trapped because the protector shifts ever so slightly. Eventually I'll try to trim them out just a bit, but it's not happening often so that can wait.
Anyway, still looking for a photo on the posts that can be placed at the outlanes to make draining harder. It was referenced in the manual, but I have yet to find the illustration it refers to, FO-320, which is on page 7 under Playfield Panel Post Adjustments. Unless that is referring to something entirely different. Right now, the game is "set" to Easier.
Ball 5 issue is/was related to the Ball Count Unit. I cleaned it up some, lots of black crap came off. I suspect grease from the zipper unit.

OP

Quoted from jlbintn:

Yeah, I think you are correct and was leaning in that direction myself. Outside of drilling holes to push them a bit further up....
not really sure I want to do that to a 50 year old playfield, and I'm not sure the plastics would look right with the upper posts extended, even a little bit.
I think I'm going to clean the spinner cogs. There was a lot of gunked up grease globs on there. They have a black look to them. I changed out the ball plunger spring yesterday, and even it had a greasy feel to it, all the way up the rod to the tip. Somebody really liked grease.
