Quoted from topkat:

I dont know, maybe? it so strange when I watch the skirt, as i activate it on the pf, even with no spoon there it has allot of movement in 270 degrees of activating, but the upper side facing the lanes when I push on it the tip doesnt move as much at all .

Well; if you decide to give it a shot; I now sell translucent pointed skirts. Having said that; I'm not sure point skirts would help ... but there has to be a reason someone created it.

The ones with the point are to help prevent a ball from getting hung up on the top of the skirt and needing to be nudged loose. Your test without the spoon even being there sounds like there must be something physically wrong with the skirt or how the pop bumper unit was assembled or something is misaligned, if was me I would pull the whole pop bumper assembly out (the parts above the pf) and check the parts.

I have no back box lights. On the board that has the spinning disk. I'm trying to figure out the schematics. What controls or powers these lights? Fyi. I do have lights on the outer glass. "The ones along the back box perimeter." Any help would be great. Thx.

#2005 16 days ago

My bad. Traced it back to the fuse. Schematics were just a tad tricky to follow. Thanks. Have a good one.

#2006 15 days ago

Hey guys. I'm excited to be apart of the club. I bought my BH a month and a half ago and am now just getting around to the guts of it. Boy what a beast. First off the BH I bought was suppose to be in good working condition, it even a had a video of game play. Shame on me for taking someone's word as it was all ready to go when I went to pick it up. Got it home and set it up for a good nights playing, low and behold some things didn't work.

Upper drops didn't reset, spinning disc motor was loud as hell, center pop didn't pop, lower playfield tube kicker didn't kick, lower 4 bank drop doesn't reset, lower captive hole doesn't kick and the lower captive hole 3 arrow lights don't light up. Last time I will ever buy without seeing it in person.

Anyway I have fixed most things on the upper. It had a couple blown fuses and also the center pop spoon switch was loose and needed tightened.
The lower PF I haven't made any progress yet. The tube kicker I'm pretty sure is the transistor so I have a couple of those on order, but haven't figured out the captive hole, 4 bank drop reset and the three lights.

System 80s are definitely different. Any input or help is much appreciated on trouble shooting the last few issues. Thanks

#2007 14 days ago

Welcome. This machine is a beast! I'm constantly working on it. And it's not easy to work on. It also pops fuses constantly. I keep it because it's a stunning looking machine and has interesting game play. Flip on and enjoy.

I guess I feel really lucky that I've never had a problem with mine. I've literally had both my BH and HH both up and running without fail for over almost a year now. Haven't had to touch a thing.

#2009 14 days ago

Working on a Customers Black Hole. Fixed many issues and a new one sprung up.

The Pop bumpers trigger the lower playfield initiation, ( Lower playfield comes to life as if ball was sent down to it) Of course This shuts down the upper playfield and balls in play drain.)

I do not have a manual. Does anyone have ideas as to track down the issue?

Thanks

One of the switches in the lower playfield too sensitive and vibration triggering an event is my guess.

Just out of curiosity, have you already performed the ground mods for the game? Did you replace the orange capacitor on the bottom of the cabinet? Also, the under-playfield transistors may need pull-up resistor installed if they aren't there. I was afraid it would take me forever to get my BH working. It took a while, but since I've had it running I've had very few problems.

Clients machine came in just a few days ago. It doesnt have the ground mods yet something I am planning to do.

I took care of other issues first , Dead displays, Burnt sling coil, install nvram. I believe all of the boards need rework ,Caps etc.

Connectors need repining and POP bumper boards all need rework. I wanted to discuss this with the client for his approval.

There is some odd cross talk with the POPS as one triggers another with the switches correctly gaped.

In other words not vibration related.

The triggering of the lower playfield through the pops is not due to a sensitive switch.

There is something either in the harness, connectors or possibly on the MPU where the issue may be found.

This is a first I have seen this.

#2013 14 days ago

Gdonovan took my first guess but if that switch doesn't solve it I would look to the PBDBs. I can't recall if the an activated switch downstairs makes the 24v/38v switch or not, but if they did, my guess would be that the PBDB on the lower playfield are being activated by stray voltage (I believe their 5v is all tied together) or the header pins need to be reflowed. If those PBDB header pins are cracked they may fire upon vibration and switch on the lower playfield.

But my guess is the gravity tunnel switch being out of alignment. I had that issue on my Haunted House before the shop.

Check your diode strips to see if you have any shorted diodes. That could be another place to check for clues. But again, as I recall, the 5V on those boards is daisy chained in a pretty flimsy way on a point towards the back of the playfield.

Was leaning towards the PBDBs but need the clients approval before reworking them. Will speak with him this eve.

Hopefully reworking them will fix the issue.

This might be totally unrelated, but if you aren't against going non-original I suggest a modern replacement of the power supply. It will reduce energy consumption and heat. It can also improve the grounding situation.

I would get intermittent coil chatter, triggering of the bottom playfield and random sounds after several minutes of play (with ground mods done). I went with a modern replacement, even removed the ground mods (except for the beefed up connector), and have had no issues since.

If it were me I would go with all modern replacements. Its the clients call.

#2017 13 days ago

Had a chance to look at the machine again and its the Left drop bank that is initiating the lower playfield.

I was mistaken in thinking that the Popbumper was the cause as I didnt notice the ball hitting the drop targets duh.

The center pop bumper is machine gunning and then causes a tilt. Another issue.

I can begin to narrow it down by following the connection to the drop target bank.

#2018 13 days ago

Sounds like you've got a switch matrix issue then...

#2019 13 days ago
Quoted from zacaj:

And how does one go about dissecting and fixing a switch matrix issue on a Sys80 if the switches in question are apparently fine? Something from strobe 3 shorting or something on return 2 shorting?

#2020 12 days ago

Follow up. I

Upon starting the Ground mods I discovered that there was no Ground wire in the Back Box!

After addressing that and doing all of the ground mods, I tested all of the Diodes in the machine (All tested good)

I powered up the game and played 3 perfect playing games then boom the same thing happened 3 stand up targets hit and the lower playfield initialized.

I turned the game off and powered it up again and had 10 games with no issues.

I even tested everything with ball in hand for about 4 games.

It appears that the ground mods are working but not sure what caused the issue on the 3rd game.

The client ordered all new POP bumper boards and a power supply rebuild kit.

Once I install those maybe the issue will never show up again.

Any thoughts on the cause aside of not having any grounds?

#2021 12 days ago
Quoted from Eddie:

Do you mean the lettered drop targets or the captive hole round stand up targets? If it were the drop targets, are they any 3 in particular that make it happen? If it is the "B" "L" and "A" then I would have to agree with zacaj that it looks like a switch matrix issue. I guess, as I suggested above, I'd check the diode strips and see if they need any attention. Maybe they're shorting out or something like that.

It was the stand up targets the one time after the ground mod was installed but I havent had an issue since.

Im still working on the machine so I will have time to see if it rears up again.

#2023 12 days ago

Question about a Spinning disk mod.

I had a BH in my shop about 10 years ago and its motor was wired to run only when the lower playfield was initialized.

Would anyone know the wiring schematics for that Mod?

#2024 11 days ago

Does the original game programming have a free play setting?
Mine has all the recommended ground mods.
And all original boards.
I have to coin it up every time I turn it on.

There are about a half dozen ways to achieve this. My preferred method is bending the center chute leaf switch so that it's activated when you hit the coin return. Easily reversible, easy to do.

#2026 11 days ago

So no OG free setting.
Just mod workarounds.

Thanks for the info.
Cheers.

This one as well will give you free games. I made mine with alligator clips instead of soldering it.

My black hole has a somewhat random problem that doesn't seem to have any real negatives.

The display on the lower playfield, and on the credit # and ball # sometimes comes up as garbled lines.

Sometimes after it warms up, it just goes away.

Other than this my game has no issues.

Quoted from TronGuy:

Could be 5101 RAM on PCB. or it's socket connection issues.
Also, maybe need to re-pin connector and check/reflow solder at backside of display.

I'd also shine up that display board's male connector pads with a fine scrubber pad and then wipe clean with alcohol-dampened cloth. Same with the board connector pads on CPU board J2 and J3 (two connectors on right side) which are involved with the display data.

Guess I gotta be a little more careful when trying to pull a sticky dirty worn-out sleeve out of a flipper coil. First time for everything. C-C-CRACK!

I wouldn't be that upset. It if was that stuck the coil was likely shot anyway.

Quoted from Mad_Dog_Coin_Op:

I think the old coil was okay, after I cut it out I was able to pull the sleeve out. Happened so quick I'm not sure but I must've slipped while I was pulling on the sleeve and it jerked the coil breaking off the whole set of lugs. Put a new coil in yesterday and all is good.
