Ok guys. Need some help. Just picked up a High Speed project. Needs an MPU board. Which one do I get for HS? There are many variants of system 11 boards.


#1769 2 years ago
Quoted from AMBoggs:

It is just System 11 with no suffix. Road Kings and Grand Lizard have the same board.
Is the board missing? Repairing them can sometimes be cheaper than buying a new board, assuming you could find one.

Not missing.

But issues!

Quoted from Chosen_S:

A good board guy can rebuild those traces with a little time

cool - I emailed some more photos to John Wort for a quote.

Anyone have recommendations for a board repair person?

Ok. So I sent my MPU board off and it was repaired. The game now boots, but the insert lamps don't work. The solonoids worked for a few seconds when I replaced the fuse in the small board in the lower right of the backbox, but the fuse blew right away. Where should I be starting the troubleshooting?

Any help is greatly appreciated.


#1798 2 years ago

Ok, so I replaced the fuse on the flipper power board with the right one (had a 2.5 instead of a 5A fuse) - Flippers started working. For a while. Inserts still don't work. Now no coils are not working and I think this is why: Should I just replace the power supply board?

Quoted from dyopp21:

Glad to join the club! Got this HS from a prison guard in Arkansas who got it from a prison in Arkansas. It was in pretty bad shape! Finished the restore a few weeks ago.

looks great! Did you install the overlay?

#1804 2 years ago

Anyone have a playfield they would sell? Mine is in terrible shape

#1831 2 years ago

Ok here is the deal. Need some wisdom. Finally got the game working 100% with no more switch matrix issues. So now the last remaining issue is killing me. Game plays fine for a few games. After it gets warm it will eventually freeze and go to GI only. It won't reboot. This will happen in attract mode or while playing.

The MPU is still getting 5V and the MPU display readout is "8". Any ideas on where the cause and solutions?

I am able to power cycle it and play again but it will freeze and go GI only shortly thereafter.


#1832 2 years ago

grumpy any idea here? I think it is heat related.

#1835 2 years ago
Quoted from GRUMPY:

I would check for the correct voltage, 5 and +12 at the CPU. I would check for AC voltage on both of these. I would swap both CPU chips on the Cpu board. I would check for cracked header pins for the power cable that goes from the power supply and CPU board. Also remove the game Roms and look for dirty or bent pins. Clean pins with an eraser and reinstall Roms. Last would be to monitor the 5 volts while someone plays multiball until it locks up.

Thanks. Is there a +12v test point on the CPU? The 5V tests fine at the test points on the MPU board.

No I did not. Which plunger spring at you using?

Use the red one.

So now I am having an issue with both hideout kickers fireing when I boot the game on. See the video. Is this a switch matrix issue?

#2113 1 year ago
Quoted from FireGamer3:

I would check the switches the game might think there is a ball there

No balls and the switches themselves are not activated.

#2115 1 year ago
Quoted from FireGamer3:

Ah, then I guess it would be the matrix. But don’t take my advice as HS is my first machine so I’m still somewhat new to the repair and restoration of pinball machines

gotcha! thanks for jumping in regardless!

Here is one that came up on my High Speed: When I power up the game, I hear the relays clicking under the playfield. The start button won't start a game. The first time I press start 3 relays (under the playfield) click a few times and then stop. I can go into solenoid test and switch test and everything works properly.

Any ideas on this one?

#2153 1 year ago
Quoted from Freeplay40:

Sounds like the game is looking for a ball. Be sure you have 3 balls in the game and that when they are in the ball trough, they are all registering.

Nope that’s not it.

#2157 1 year ago
Quoted from PiLgRiM:

Check the switch right above the ball shooter. It needs to sense the ball there after the game starts and it pops one out of the trough. It will try a few times, then give up from what I recall.

It’s not that. None of the playfield solonoids will fire. At all. They won’t even feed them into the trough. If I manually put them into the trough a game will start. But none of the playfield solonoids fire. Just the flippers work.

All fuses are good. I can hear the these three relays clicking a few times.

#2159 1 year ago
Quoted from GRUMPY:

There is a lone 2.5 amp fuse in the back box that is blown.

Damn. You had me excited for a minute. This fuse is fine unfortunately. All solonoids work fine in test.

#2161 1 year ago
Quoted from PiLgRiM:

Check ground at 3J3 in the power supply. That’s where those relays need to connect to ground to fire the connected solenoids.

That was it. You are da man.

Quoted from billsfanmd:

What are ballpark prices on high speed? Selling one for a friend and wanted prices. Decent shape. Leds and board just serviced.

Seems to be all over the place. I would say $1400 for a working average example. Seen them range from $1100 - $2100.

#2248 1 year ago
Quoted from Chosen_S:

I hope it doesn’t cost $400. Is there a link to more info?

Looks like it is $420 actually. Big Daddy has been doing early preorders /sales and K’s Arcade has it listed at $420.

Quoted from Tomass:

About to join, I think. Trading a working Rescue 911 for a High Speed with a locked coil. Playfield looks real nice though. Pinside shows value in their favor, but I prefer sys 11's mostly. Never played High Speed. Anyone have any thoughts on this trade? Also pins are limited in AK so hard to find specific games. Not like I can wait for the next HS.

This trade is a no brainer. Classic Steve Ritchie flow, awesome sound package, an absolute classic. R911 isn't even close for me.

Moving to this thread since the board is now in a High Speed. Issue: upper left jet bumper not working. grumpy

Quoted from GRUMPY:

Use your logic probe on U-49 pin 1 and pin 2 in coil test. Do you have pulses? Yes, the check U-50 pin 1, do you have pulses? Yes, then replace Q-76. Let me know what you find.

U49 1 and 2 have pulses. U50 pin 1 has pulse. Replaced Q77. Replaced Q76. Still does not work.

Also both kickers and one more jet bumper are not firing in coil test.

Edit: 11A board may need a jumper to work properly in HS. Researching.

#2349 1 year ago
Quoted from GRUMPY:

If this is a system 11a board in a system 11 game you will need to add a jumper on the back of the board.

Oh ok. Do you have a link or instructions on how to do that?

#2351 1 year ago
Quoted from GRUMPY:

Remove the CPU board and look at the back of the J -18 pins 6 and 7. Are they connected to the perimeter ground plane?


#2354 1 year ago
Quoted from GRUMPY:

In coil test for the left kicker check for pulses at U-49 pins 8 and 9.
For the right kicker check for pulses at U-49 pins 3 and 4.

All works now! I just needed bypass the ground like you said. That was why I had no special solonoids.

#2356 1 year ago

Thanks for your help as always! You win my vote for most helpful Pinsider.

Ok, so I am trying to track down another issue with my High Speed. Currently, 4 special solenoids do not fire in test or game. Solonoids 17,18,20,21. (Q75,Q71,Q69, and Q77). During test, the pulses seem to be correct, so I don't think its a IC issue. Grounding the transistors do not fire the coils. Coils have power (28v). Maybe its a grounding issue? anyone?

#2442 1 year ago
Quoted from GRUMPY:

Check the molex connector for the play field.

This is why grumpy is the MAN! Unplugged molex under the playfield and reconnected. BOOM. Fixed.

Quoted from MikeVarney:

Are people happy with the NVRAM without using any batteries?
- M

100% yes. Every System 11 game I have owned I installed NVRAM. Pretty much do it instantly. I have seen too many of these boards with corrosion, which is very painful.

Quoted from PinballAir:

It is one big rubber which I believe is a 5".
And yes the assembly has to be removed.
I removed the one on my game to clear coat and it did not seem that difficult, but in my case, I had the playfield out of the machine.

No, it is actually two big rubbers. Well, at least it was on my game..
