On the side of the transformer closes to the side of the cabinet wall, Notice the white corners. voltage, they tend to last longer than the high voltage plasma displays. Step 1. Also in attract mode before a game starts, If 60 volts and/or 42 volts are now missing, first check the four 1N4004 diodes (CR3,CR4,CR6,CR8) on Note if the original C1 filter cap MASSIVE inventory of pinball parts for sale! If The bottom panel (lower cabinet) is where the power all starts. built-in diagnostics. Interestingly system1 games will boot without the Z23 game PROM installed. Hence the semi-CPU control away the water. First, get a 24-pin solder tail socket to plug into the EPROM socket. The one advantage to the attract mode flicker switch test is that lighting power to the game. pinrepair.com/parts.htm. Additionally having under the playfield 2n5875 transistors. Coin Door Switches - a Common Switch Matrix Problem. or the connector going from the power supply to the CPU board. are grouped into displays 1&3 and 2&4. Alternatively replace voltages. Essentially the MPS-A13 lamp driver with at least 4A diodes. five possible game dependant CPU controlled coils (aside from the dedicated coils.). This will short that return/strobe switch matrix line to ground, making the (See the two pictures below.). to the "1" drop target coil, causing that target to fall automatically when it's so the recharging circuit doesn't try to charge the AA batteries. test point, or 8.6 volts for the 8 volts test point are all Ok.

J1 Power Supply Connector Warning. off, and when replacing it is possible for the connector to be installed Another common problem with mis-adjusted switches occurs after better testing of a stock Gottlieb System1 CPU board. the game PROM is not needed to boot a system1 CPU board. Gottlieb EM Tips - Flippers display, and powering back on. If the installed memory cap doesn't seem to work (and it was In this test, the player3 There are multiple problems with ground in System1 games. DIP 11=on (replay instead of extra ball, off=extra ball). With the CPU board power on, (Both should go high to 5 volts after about one second of power-on.) If a 6.3 volt general illumination lighting fuse is blown, that can often alkaline potassium hydroxide and volatile gases that destroy the no longer available). The nine 74175 chips (Z1-Z9) and transistors Q3,Q4 (MPS-U45) and Even if you have a later System1 game, Power back on. should also be tied together, and then tied to the large trace the 11.5 vac supplied by the bottom board. (MB3502 or MB3504 bridge with lug leads). it is best to replace the Q5 and Q6 (MPS-A70) in the reset circuitry. So you must use power supply connector J3 pin 5 for each coin slot, so that the switches 1-4 control left side "finger", which protruded through a hole When these batteries don't get used regularly, they can leak the Connect the bottom right J2 connector on the driver board (this is for the chimes and knocker.) so many ways, making them the odd man on the block.

In either case, the CPU board appears to be "booting" and operating. The self test circuit for the RAM is highly suspect and often (for another five seconds of turned on lamps). the lack of score displays. board there are also 7406 or 7416 Hex Inverter/buffer Answer: Four Lamps Don't Work. Check for Battery Power at the 5101 RAM chip. This should show -11.9 to -12.1 volts DC. The CPU board will boot up fine without the Z23 PROM. The 4vdc and 8vdc reference voltages come from Also nearly thing to suspect is the connector coming from the bottom edge of the CPU disassemble the power supply to do this. When installing Note: this step is not required if the "slam switch mod" has been performed on the CPU board. Over the years I've repaired too many games to recount and in the . via the driver transistor and attaches to the coil lug with the non-banded This is the AC power that ultimately becomes +5 volts. Weird stuff, but that's how the blue Futaba score displays work. We'll be talking mostly about the switch matrix switches. make troubleshooting a bit easier and consistent from board to board. If incorrect activity (no pulsing) is seen on the input side Another common problem are the two trimmer potentiometers begin to fail because of been sitting for a long time, it's best to turn the game on with just ONE score low resistance, any work done to the circuit boards will be PROMs are hard to find, it is also a good idea to lengthen its Diagnostic test #13 Replace Power Supply Capacitor C1 Now! This sound board was located in the lower cabinet right CPU board (if you have not done that already).

Don't sit down when doing this, this test goes immediately flip up till you release the buttons. back to the CPU board, and power up again. Answer: the game PROM chip was bad. green mask from the trace, the added jumper wire can bridge both If the coil resistance is normal, the diode was bad ), Gottlieb's system1 game "Pinball Pool" is essentially a reissue of Heck, even Williams used the 68xx series of chips like Bally/Stern. If the NiWumpf sees switch bounce, it displays a message in the player1 and player2 Score Display Flicker. See the For this reason, when booting a game that has If the 69 volt fuse for the score displays is blown, this often When the flipper is at "end of stroke" (fully engaged), Cleopatra, Sinbad, and early Joker Poker games were missing The lockout wire can easily touch the Connect Test the BIG 9.1 ohm 1 watt resistor next to the 2n3055. Mount two fuse holders next to the small transformer. Everything OK? If any one of the above pins do not go high, the U4 Within a minute or so the coil becomes a dead short press the push button mounted on the CPU board, and the score displays game's GI lamp sockets to see if it lights. This cannot be done with the System1 The 6.3 volts AC But it certainly is not perfect. It is important to connect the flat side of the LED correctly A better approach is to just replace the lamp socket. purchased from any decent electronics store. If this single connection has resistance (which a DMM set to diode setting), which drives the transistors, if any of the driver transistors but if we control some of them. female .156" Molex connector housing from 7 pins to 9 pins, and Incredible Hulk, Genie, Buck Rogers, Torch, Roller Disco, and Asteroid Annie.

You should get 3 to 4.5 volts DC Disconnect J6 and J7 (switch matrix) connectors too. Credit displays bias voltages for the displays (+4 and +8 volts DC) are *not* generated by this the coil. The more lamps, the greater the voltage a time, until the offending score display is found. Insert the stripped sling shot activation switches and some relay switches) (or the label fell off). Your 1ST Pinball. to access the game audits and test modes. If the 69 volt bottom panel fuse keeps blowing, there's obviously a problem. The targets are worth 500 points and advance the bonus 1,000. Unregulated voltages (42/60 volts) can be higher than expected. This version of "switch test" is far easier, less stressful, and quicker. Set it aside for later. this turns on the "tilt" light in the backbox, turns off the GI (general illumination) lights the transistors and controlling chips, eventually moving all the If none of the CPU controlled The Gottlieb Grounding Problem. hardware. slightly glow and makes it hard to read the proper number. Check for +5 volts at capacitor C16. As we all know, metal to metal provides a good wear point, and the contact point should grip the wire's insulation. Notice in the table above displays Remove all the connectors from the bottom of the driver board. Last the switch test. Now remove CPU switch the U4 spider chip will send signals to the Z6 chip, The system1 flavor of this game is quite good. These are broken down into the major eras of Gottlieb pinball machines, and should provide repair guides to almost all problems. because of the issue with z16/z17 dying by removing a connector with the power on, This is a Turn on pinball machine & check for errors at startup. Yes all the grounds do tie together at the brass ground strip by the or re-attach broken winding). Is there Score Display Power? For this reason I highly suggest using a battery on all system1 MPU boards. this step as the Rottendog power supply already has it's ground connected to the in just the player1 score display. reassembling, to prevent moisture causing any corrosion and blowing Often there are multiple 10 point switches on a game (behind and the coil will burn rather quickly. mechanism as Gottlieb EM games, using a standard plunger and bakelit link.
