Hi, I got my first project machine, a Williams Fun Fest. I currently have a 100% playing Williams Swinger that I’ve had for about 10 years now. I have no history about this Fun Fest machine other than it’s all there. Which it is. At this point I did the following.. (Sorry for the long post),,, I do have a schematic and manual….

Vacuumed out the head and cabinet, Replaced all rubbers, initial playfield cleaning, rebuilt both flippers, rebuilt plunger rod, checked ohms on all coils and they were inline to the chart I found online, fixed a few broken wires, disassembled/cleaned/reassembled all the score reels, fixed knocker (broken wire to coil lug and broken wire to jones plug).

Once I assembled the head to the cabinet, powered it up I was on my way to finding and fixing other issues (Fixed match unit, realigned, Fixed replay reel, broken wire on coil lug, Fixed Player unit (game always on Player 2, realigned), Fixed kick-out hole at top of playfield (broken hole plate), Fixed Ball Return kick-out on left side drain.

So at this point, I can now play complete 3 or 5 ball games, 1 player or 2 player or 3 player or 4 player games.
I have 2 issues right now and Im stumped.
#1. When I press the credit button (red button) on front of cabinet to start a single game or multi-player game, the Replay reel decrements accordingly, the game plays like it should, but the “1 to 4 Can Play” lights for 1,3,4 do not work but the 2 does work. I replaced the bulbs with new, I was able to test the bulb sockets and they all are good. I even jumpered a light socket to the “Coin Unit” at the 4 different locations on the board and the jumpered lights did light accordingly to the number of Players I chose. Is this telling me I have broken wires for 1,3,4 from the “Coin Unit” to those light sockets? I did not unravel the wiring harness from the “Coin Unit” to start tracing for a break, I was wondering what the easiest approach is before I do that.

#2. When the bottom left rebound kicker is activated, the kicker, kicks the ball as it should but it does not record any points (10 points) and does not activate the chime. This issue occurs for 1 player or 2 player or 3 player or 4 player games. More broke wires?

Thank you for taking the time to read this post and assist in fixing these issues.

Thanks for the insight... I think I'm on to something... Issue #2...

The outlane switch wiring looked OK. (Similar to the Swinger). So what I did was I jumperd the end tabs of the kicker switch stack and the 10 point reel advanced and the chime sounded. So, I'm thinking it's actually that switch stack of the kicker.

I still need to follow-up on the "1 to 4 Can Play" lights..

thanks
Steve

Update: The Good... The Same...

Good:
Issue #2- The lower left kicker switch had a bad solder. I resoldered the kicker switch and the 10 point scoring and chime now works.

Same:
Issue #1- I cleaned the contacts of the player unit. Can my start alignment position be confirmed by the attached photos. I do have replacement springs on order for this unit. The clock spring is wound 4 times. It advances and returns as it should. I still get the same results with the "Can Play" lights. I'm checking some relays now to see if I can see a difference from when I select 1 Player Game to a 2 Player Game (since the "2 Can Play" light works. Or should I be directing my attention somewhere else.

thanks
Steve

Hi Everyone,

"Can Play" light issue is resolved!

Thanks for your thoughts on this.
All suggestions I checked seemed OK. So I started from the beginning again... checking for continuity.

So what I wound up doing was I traced the wire from the Coin Unit to the Jones plug again (topside). I found continuity on the topside of the plug and noticed that I did not clean the post connections of this Jones plug (all others were cleaned, I overlooked this one). I tested continuity to the post, nothing on 1, 3,4 but 2 was good. I then cleaned ALL the posts on the Jones plug and BINGO, continuity on all 4 posts. I plugged everything back in and BINGO all lights 1,2,3,4 for the "Can Play" are now working.

I'll remember this as "Check the easy stuff" it may save you time and aggravation, but it's also a learning experience that won't be forgotten.

Thanks again for your assistance
Steve
