You'll want to check the contacts in the "Player Reset Relay" and also if that relay is energizing
when the Frame Unit suppose to step up to the next frame. If it's not energizing, you'll want to
clean (and always a good idea to also lube) the wiper and wiper boards on the Coin and Player
Step Up Units. Those two units correspond together to tell the Player Reset Relay to energize
which tells the Frame Unit to step up..
Also cleaning and lubing (light weight grease) the Score Motor wiper board is always beneficial..

The Extra Shot stepper I believe is on a different circuit to the pin reset relay.
And no, stepping up the frame unit will not energize the pin reset relay..
When it is time for the Frame Unit to step up, does the Player Reset Relay
energize? It's been quite a while since I worked on a 60s shuffle, so I'm not sure
exactly where it is, but that relay is there in the backdoor somewhere..
If the Player Reset Relay is not energizing, you'll want to carefully check and clean
both the Player-Step-Up unit, and Coin-Step-Up unit..
The Pin Reset Relay energizes through the Score Motor's wiper and wiper board. There's
other contacts in that circuitry, but cleaning the Score Motor's wiper board is important..

Yes, it's important that at least all the main components have been gone through..
On the Player Step Up wiper disc. It most likely has the spring loaded wipers. You'll
want to make sure that those all slide in and out freely. When going through a machine,
I always put a light weight oil (I like Remington Gun Oil) in each wiper hole and then
push them in and out to make certain that they have no stickiness..

I agree with the manufacturer's recommendation to do very little lubricating. Don't lubricate the wiper holes. I know cleaning them is harder but it's better. Here's an excerpt from the Williams Skylab manual.

Doesn’t the pin reset relay operate off a score motor cam bladed switch that fires at about 350 degrees ? Have you checked the switch on the pin reset motor cam thats used in the pin reset relay hold circuit ?

Yes, the pin reset relay does activate through the score motors wiper and wiper board. He did mentioned that when he stepped
up the 10th Frame unit, and the pins reset, but that travels through another circuit, but it did suggest that the pin reset relay along with
the run out switch on the pin reset motor's cam is doing it's job okay..
Back in the 90s, I got in ball bowlers where the rivets were worn right off the wiper blades. I replaced the rivets, lubed the wiper
boards, and since the mid 90s, they now show very little if any wear, and all has been problem free. These are machines that got/get very much play..
I also had problems with the snowshoe wipers where some would stick and make pour contact. Since the late 90s, I used Remington
Gun Oil (which contains teflon) in those snowshoes, and haven't had any problems. This isn't finding these positive results with just
10 or 12 bowlers. This is using this procedure with many, thus I have to stay with wants been successful..
Some old vendors use to tell me that they don't grease anything. That just collects dust, which probably explains why I find so many worn
wiper blades and full tubes of lube that the manufactures sent with the machines..

Progress. Good news. I'm not sure if it was mentioned, but making sure that the switch stack screws are
tightened before adjusting is always a good idea..
The Frame's reset and step up coils fire at the start of the game because it's going through the Start Relay..
For the Frame Unit to step up during game play, the Player Reset Relay needs to energize. If that relay is
energizing, you'll want to first tighten the switch stack screws, then clean and adjust..

Okay, I was going from memory from 50s Ball Bowlers. Had to check the schematics..
If you look at the 8 position on the schematics, a bit up from the bottom you'll see the Extra
Shot disc displayed. You'll want to clean and lightly lube its wiper board. BTW, I clean by
spraying a solvent (I use carb cleaner) on scotch brite, then wipe off cleanly.
Also in the circuitry you'll see is contacts from the Score Control Relay, Repeat Strike
Relay, and a set on the 3rd position Score Motor (which I'm thinking you have already
cleaned and adjusted), but you'll also want to service those contacts in those relays mentioned
above. Just for a note: I see from the schematics, your machine's Frame Unit steps up
at the start up of a game through the Frame Unit's disc when it's on the 0 (totally reset)
position. It resets at the start up of a game through the Start Relay..
Check if you can find that circuitry on the schematics at 8 (couldn't see the letter, probably
C or D), and follow it up through to the Frame Step Up Unit. You'll see those relays mentioned
with the switches in that circuitry NC (normally closed)..

I'm no expert in what's best, but it does seem like a good idea to start another topic maybe
titled " Guide to read schematics" for my Pyramid Bowler.
I'm not much good with computer, so I myself would have problems guiding you for help reading
schematics, but many here are..
Yes, these schematics I'm sure have differences, but once you get started, I'm certain it'll come fairly
quick to you..
What disc are you referring to that a snowshoe wiper (spring loaded wiper) is getting hot on? I'm sure
the Player Up has them, and I'm thinking the Game Selector Step Up also..

Had you checked the contacts in these relays already mentioned, along with the
contacts in the 3rd position score motor?
Also, the circuitry goes through the Extra Shots wiper disc when the Extra Shot
Step Up Unit is in it's total (which it normally is) reset position. You might want to make
sure that the Extra Shot's wiper is aligned properly and squarely on its rivets..
For sure the Extra Shot Relay is energizing when it's time for the Frame (and)
Player Up Units should advance, right?
