Quoted from EvanDickson:

The one at the eject point works too. I don't think it could be a switch issue, since the kick out cool should fire every time in test regardless of switches. Hoping it's u2. Otherwise I guess I'm looking at a broken wire that doesn't look broken, somewhere between board and coil.

Don’t forget the driver board only controls the relay on the solenoid expander. The relay completes the circuit to fire the coil. It’s designed this way because the coil draws too much current and would overload the driver transistor. The relay can handle the extra current so it becomes the “driver”.

With the backbox open and the playfield up, ground the tab of every driver transistor until you find the one that controls the kicker (ignore this if you already know which one it is - sorry, I don’t have the means to look it up right now). Make sure the relay clicks every time you ground the tab. You may have to disconnect the coil to hear it. If that’s good, run the coil test and make sure the relay clicks in every cycle. If it does, then you know your problem is with the high current contacts in the relay, the board connector, or the wiring to the coil. If the relay clicks intermittently during the coil test, then it is driver related.

Oh will try this tonight, the relay doesn't appear on the board schematic. It's only for the kick out solenoid? If yes, then this sounds promising.

Basically, this circuit is a copy of the flipper circuit (sans cabinet switches. )

Yes it’s only for the kick to playfield solenoid since it’s the only coil that cannot be controlled directly by the driver transistor.

This was it, thank you! Just a loose connector on the relay board, didn't even know it was part of the system.

New member here! I love this game! Any leads on a good playfield? Mine is roaches but I will still play it it’s a great game it deserves a new playfield on mine but a proud poppa here!

My Centaur will sometimes continue to try launching a ball after it's already been launched. Example: You complete all four guardian lanes, and a ball is launched. A couple of seconds after it's launched the game attempts to launch the ball 3 or 4 more times. (You can hear the coil firing, and the sound effect, and see the playfield GI blink.)

I think this happens because the game doesn't see the end of trough switch (switch 33) close when the ball zooms past it on the first launch. Apparently it's programmed to give up after 3 or 4 more launch attempts.

I have adjusted the switch and even replaced it, but it still happens about one in every 10 launches.

This error doesn't add points, but it's annoying, and since it makes the pf GI blink it also blinds the player if the room is dark (which is how Centaur should be played.)

QUESTION: Is this a common error? Does anyone have a Centaur on which this error NEVER happens? If so, I know I should be able to fix it.

Possible cause: The wire actuator on my end of trough switch was replaced at some point, and I think the replacement wire is shorter. This might prevent me from being able to adjust it or bend it into the optimal shape.

And before anyone asks, yes, I've replaced the switch capacitor. Thanks for any feedback you can provide.

My Centaur II has it too. Haven't tried to find out why yet.

Try the first ball trough switch? I modified the first ball trough switch to a long flat blade style...
It stopped all ball trough read problems; as far as I know.

Possible part number that you have replaced with?

#1011 4 months ago
Quoted from Antennaejim:

Possible part number that you have replaced with?

Try an outhole style switch that has a light weight actuator...
Or a Williams micro drop target style switch...
You have to modify to fit and you have to drill new mounting holes in the bracket?
I believe... it has been many years sense I have done it to a Bally Centaur.

Is there a current part available for the queens chamber drop target assembly drop target stop from the housing. The part I am looking for is the square metal piece with a screw coming through it, attached to the spring in the picture. This piece stops the target from over extending on the playfield. Thanks in advance!

You are going to have to find the part or have the part reproduced.

I would need a part number to find it anywhere. And it’s not listed in the manual. Does anyone happen to have a part number?

#1015 4 months ago

After letting one go in 2013 ...
Have been looking for one ever since.
Unsure If it has been sited for a long time as it had a $1 coin in the coin box dated 2001...

Any one know the part number(s) for the lock / cam / mechanism for the backbox? I have none of it, which bugs me a bit, and the manual doesn't identify parts besides electronic components.

#1019 4 months ago

If you have the part number. Check with Pinball resource. He has some things. All by part number.

Pinball resource normally carry both the left & right bracket, I have enquired about these before. About $11.00 each from memory.

PM me your email address and I'll send you what I have. Haven't burned them in a few years so not sure which files you need.

hey does anyone here have experience with glare free glass on a Centaur? b does it look better to the point it is worth the price?

#1026 3 months ago

I just got the playfield swap completed....feast your eyes on this

I wanted to offer my Centaur apron cards to the group that I recently created for an owner. I print on photo quality printer with OEM inks and high quality thick ultra-gloss OEM paper. I then coat with clear gloss vinyl for protection, razor cut, and color edges so you don't see white around the perimeter of the cards.

I sell the cards for $10 a set which includes US postage. If interested in purchasing, please PM me.

Would you happen to have a pic of the cards installed?
Also do u have any mods for centaur?

Quick question. What size spike post rubber do you use for the three spikes? And lastly. Does this rubber layout look correct? I followed the manual the best I could.
Thanks.

#1038 36 days ago
Quoted from Fortytwo:

1) the regular large size. Gottlieb ref. A-15705 27/64" o.d.
2) The top right rollover ring is off. The large ring should around four post, not three.
3) Take your 6th 2" ring and fit it around the right drop targets. Or/2-1/2" rubber ring.
Note: Bally doubles their playfield drop target rubber rings...
(check the games back and middle flyer pictures for clarifications).

#1039 36 days ago

Thanks. So to be clear the right top lane guide should be one sided then.
I’ll adjust tomorrow. Waiting for the lane guides and pop parts to come.

Next question. Does anyone have examples of red or black pop skirts on? I’m considering changing the color to spice it up a touch.

#1040 36 days ago
Quoted from Fortytwo:

Yup. The top left plastic guide rails are doubled (Bally part #C-693-11).
The far right plastic guide rail is single ( Bally part # C-694-11).
Note: Bally part # can be off.

I have an Austin Powers up for trade if anybody is looking to switch up to something more modern. I want in the club!

original paint or new paint.........It's killin me....my original paint is not terrible but it is not perfect.....i sit here and i look at my glorious Centaur with its perfect looking CPR playfield replacement ready to go back in....i am working on restoring the coind door and the rest....i bought a stencil kit but I just am scared to death to screw this up!! What do you all think? would you rather see a Centaur with a flawless shiny new paint job, bondo, stencil cab or would you have much respect for an original cabinet with a few scrapes and scars? It's like do i replace the plunger or honor the years of play on the original plunger. What is important for you guys, the true fans? I think the new playfield honors the art and restores the game to its wonderous glory but how far does one go?

I'd rather see an original cabinet myself! Sometimes when they are painted, they look too good, which ruins some of the originality

#1045 3 days ago

I'm in the club! Thanks to Yesh23 for helping me get one of my short list games.

Does anyone know what the ideal front/back tilt for the game is? I have eyeballed it so far and I think I'm close, but would love the opinion of the experts.

Also, proactively - anyone selling a CPR playfield, sign me up. I'm in this one for the long haul.

#1046 3 days ago

Bluespin may still have one

#1047 2 days ago

Ya I missed the CPR run as well. Someday. Not today.
While you guys are checking your bins. Does anyone have a spare triac that bolts to the power supply plate? It’s used to control GI. Mine had a leg ripped right out.

Ballpark 5.5 to 6 degrees. It's all personal preference. I think it was BigAl56 that said if the bottom of the cabinet is level, that was the intended slope from the factory.
