Nice pin to start on Ems with.^
I would read this to get a better understanding on what and where to look for repair/servicing and to generally familiarize yourself with an em.
http://www.pinrepair.com/em/index.htm <- This document is geared towards complete beginners. No experience is assumed, though basic electrical knowledge is helpful.

May want to post in the em hangout section in the future for more exposure to more em owners/tech help as more locate there in that section.

I think this is normal. Some Williams EM's have a power save feature that shuts the lights off until a game is started or the left flipper is pushed.

I'm not seeing the chime box in the photos. Is it removed? Looks like a rectangular box with three flat metal bars mounted across the top. Makes sound by coils underneath smacking the three bars.
(Edit: Just looked at the IPDB.org photos of OXO and your chime box assembly is missing. You will need to get one and re-install it.)

Could be but hard to tell at this point.

Have you checked all the fuses with a meter? Checking by eye may not give correct results. If not, start there.

Left flipper button does turn on the GI.

check the fuse or fuses under the playfield. There may be two. Pull them and check for continuity with a meter.

If the buzzing you hear is from the relays on the bottom board, the spring that connects to the latch piece is too tight. Check the section on coil buzzing on the pinrepair.com EM repair guide. That whole thing is a must read.

Oxo is a great pin, enjoy!

File the Eos & flipper buttons removing corrosion for conductivity.

When you checked the fuses did you pull them out of holder to check? If not do so...best way to check them. Also check the fuse holders.

Not sure on that game, but if you have a jones plug going from coin door, check to make sure it is clean(male pins) and seated properly. Hopefully that will get you flippers. Good luck.

the fuse holders on these williams are garbage ! I always replace the holders with a better type

check the beep for just the fuses. sometimes they look good but are not and will still beep continuity in the fuse holder

jones plug from coin door is the wires that go from the door to the the inside of the cabinet. They can plug and unplug

Yes, just as -Jeff(way2wyrd) wrote^^^

Thanks for the follow-up and thanks. Glad you got it working.

Not so familiar w/Williams but some of my 2 cents that might help.

Flipper buzz...could be the coil stops are worn....or plunger/link/assembly etc. You wrote you checked EOS but make sure it's clean and gapped correctly.

For the 'O' buzz...I would check that relay and make sure contacts clean and switch(s)adjusted properly. Sometimes the armature(metal plate on 'top') can be a bit out of place on the relay so check that too. And yes...don't burn it up...yet. ; )

Not sure on the most recent problem. Are you saying all 4 players scores don't 'add' properly, or all 4 players DO score the bonus.?

Hopefully others will chime in. Good luck.

If not familiar w/the pin repair sites here are 2 great ones...and thanks to all of those who contributed to make them possible.

It sound like the carry over contacts on the 100's reel is not gapped correctly.

Don't see this topic in the EM section, if moved there, more EM folks would see it. (moderator?)

I would have agreed with Garrett about the gabbing of the contacts on the 100's reel not being gapped correctly. However if it's a central problem there is probably a relay that is activated by this 100's reel which fires the 1000's relay whichever player is active. I don't have this game or schematics, but I'd look for a relay being activated which would activate the 1000's reel and then look for a dirty/mis-adjusted switch on that stack.

I think Garrett is right on the 100 reel switches.

For better clarity for all of us, lets all call the reels by the digit position they represent. Each set of score reels has one stationary "0" on the right. Then four more from right to left. "10's" "100's" "1,000's" and "10,000's"

There are three pairs of switches on each score reel that tell the game what position the reel is in. The "9" position switch is probably out of adjustment on the "100's" reel. This is why it does not tell the "1,000's" reel to add one when the "100's" reel rolls from 9 to 0.

Steve Fury has created a great animation to show how this works and I can never find it when I need it. Hopefully he will chime in here soon.

I'm a little late to this party so sorry if this has been addressed:
I bet the playfield switch for the "O" is getting stuck. Is this a rollover button on the playfield? Make sure it moves smoothly.

If you play a 2-player game, does it score correctly on the 1000 point reel for player two?

If so, look closely at the small switches on player two 100 point reel. Operate the reel manually and watch the switches closely to see how they change state at different reel positions. There are three positions. One position when the number 9 is displayed, One position when the number 0 is displayed and one position when numbers 1-8 are displayed.

Now compare this to the 100 point reel for player one and I bet you will see a difference. Also, look for loose wires while you are there. If you do not see a difference in how the switches change state and there are no broken wires, then carefully clean the switch contacts on "player one" 100 point reel.

This is new information. Check your player stepper unit for broken wires.

Yeah, that kinda threw me for a loop Pafasa. Angyalpor aluded to this right after my post. I've never had a Williams game and wasn't sure how the scoring logic was routed. But all the manufacturers are similar in design. Unless there is a really odd coincidence that someone misadjusted all four 100's rollover switches. Don't expect that's the issue but you never know.

What else would cause player 1-4 to have the same carry over problem on the just the 1K reel?

It's an interesting problem to say the least.

Angyalpor, can you take a video of what the games is doing?

For the 1000 point reel not incrementing when the 100 point reel rolls past 9 to 0, Check for loose wires and switch adjustments at the 100 point relay, the 1000 point relay and the player unit.

Schematics are on IPDB.org

u2sean, sorry I missed your post about the score issue. I also missed OP's post about it happening on all four players.

Did you find any loose wires on those three units I mentioned?

There are some people here on the forum that would be great help with this, but the thread is in the wrong sub-forum. These guys are just not seeing this. If it were in the EM Hangout, I know of a couple guys who can read the schematics very well. I feel like I am guessing at anything beyond what I have already recommended.

Contact a moderator and ask them to move the thread.

No, Not "Remove", "move"

I have contacted a couple others too about this thread. Lets get this game working!
