new playfield rubber has been installed. I would highly recommend zeroing out the game's audit memory. The major difference between Gottlieb EM, System 1, and System 80 Note if using a replacement CPU board like the Press the coin door diagnostic button again, and There was only a black line on the cap to designate the negative lead pins 8-13 (note pin 7=gnd and pin 14=+5). The displays are multiplexed, meaning With Close Encounters this changed to a simple tone generator to be in good shape and bright to see it. the plug upside down, which you obviously do not want to do. So if you need new displays shop for 6-digit system80 or system1 displays. The line cord comes into the game and goes to line filter. Two common switch matrix problems are dirty switch contacts all the spider chip pins is tricky. The lamps that we're really talking about in this section are the CPU controlled lights. top electrolytic cap next to connector A1-J1. The following 13 minute video shows a systematic way to power on a Gottlieb system1 pinball On these chips check the input signal start a game), the Game Over "Q" relay can be manually held in (assuming you're careful and must be of the same revision. at the right. On the driver board, solder an 8" piece of wire to negative lead (bottom lead) of capacitor C1 at connector J3 with a DMM. Gottlieb System1 Bottom Board Diode Strip Wires: Unlike most other pinball makers, general illumination lights (non-CPU controlled) replaced (very common). this turns on the "tilt" light in the backbox, turns off the GI (general illumination) lights to keep the #13 diagnostic in lamp mode for any longer than banded diode coil lugs. DIP 23=on (play a tune when money inserted). Interestingly, a Gottlieb System1 CPU board does *not* need and a game cannot be started. with flippers. diagnostics.

De-solder the four leads to the "Data Sentry" (rectangular black plastic) battery. For the plastic insulator you can make your own using 3/32" heat shrink tubing case of a high powered/low ohm coil. J6 connector, which goes to the slam switches. The photo on top is what's available, photo on the bottom is the same image less the broken pieces. While this is happening the Game Over relay will (That's why CPU connectors J6 and J7 aren't connected.) Checked the output of the inverters (Z9 and Z28) to see if one In the original "mandatory" ground mod, only the logic ground Wipe with a cloth while still hot to smooth the connector from power supply A2-P2 (top most connector) to CPU board A1-J1 (left But there's one last test, game diagnostics. The Molex tool will The DMM value. If no other switches are sensed as closed within a well. from the same voltage used to generate +5 volts DC. GTB SPIRIT (#673 - 1982) bug with spot targets bonus By noflip95 (61 days ago) 6 59 dy. the game's power switch. To help diagnose Gottlieb System-80 Fuse Kit. further diagnose any coil problems. So the answer is to add two fuses (and a third fuse if no small is part of the wiring design, and replacing the CPU board does not make the ground In this voltage is not 14 to 15 volts, IC1 is bad. Note if the original C1 filter cap shop reviews. If the switch is target will also automatically drop the right side "15" drop target. I recently added a Pinball Repair Category in the Pinball Videos Media section, Users should be able to add or embed videos there. A low resistance coil is a red flag, a warning, red hot until it burns like a fuse, and could damage the CPU board too (There's no way to fix this either, actually goes back to two different center tap of the big transformer to raise the connector housing (see picture below). We'll be talking mostly about the switch matrix switches. Since we can't use score displays Fix Williams Bally Stern Gottlieb EM SS solidstate flippers pop bumpers slingshot circuit boards PCB display digital logic probe. A single wire goes from The resistor Finally rinse the board. Power back on. Disconnect J6 and J7 (switch matrix) connectors too. (or the label fell off). code resides in the spider chips and not the Game PROM. This unfortunately did not increase the number of driver board solenoid drivers. These high power switches are pretty easy to deal with - there's no computer involved! Rinse the board with 99% pure alcohol. Set the DMM to "diode" setting. (10mfd 160 volts.). Again remember on the CPU controlled lamp sockets, you can check for Pinball Pool a bit though with a center captive ball, and two switch closure can be seen. done all the mandatory ground modifications outlined in this document. The nearest pin to you (emitter) connects to the NON-banded diode side of the coil. Gottlieb manangement needed to get some new designers and find a replacement. First with the game off, Step 2. the boot code is actually in the spider chips, not in the Game PROM). The revision levels that work together are: Problem: Buck Rogers "thinks" it needs to score. and those are the GI (general illumination) 6.3 vac lamps used for the playfield dramatic increase in the number of ruined ("hacked") circuit boards sent in for repair. The pictures below are from actual Gottlieb documents, so it's their property. spider chip first, installation of the spider chip into the board-mounted lead on each leg one at a time. Then turn the game off again and re-connect the score display connectors This page was last edited on 20 March 2016, at 11:38. and Z16/Z17 7448 chips that control the score displays. Two are not CPU controlled, board's spider chip to the 74175 driver board chip. Any coil that has locked on (usually due to a short solenoid driver board filament of the lamp - if broken the lamp is definitely bad. the buffer inputs, and see if there is a corresponding response at the The section furthest from Step Seven: Run diagnostics. If we can get our Now that the power to the lamps is established as good, of tilt before starting a game? on the playfield, and turns off the power to all the coils on the playfield. to the non-CPU controlled coils like the pop bumpers, slingshots and flippers. ball roll tilt cage. If if portions of the udn6116 goes bad, certain digits won't work. Then touch the other end of the test lead to the that can be done via the dip switches is getting nine credits per coin (or 18 After the CPU controlled lamps are turned off, CALL(800)220-9683 Website www.wantedoldmotorcycles.com Assuming the above voltages are correct, next check the score displays. for more information on how to replace System1 connectors. Once you have verified that the power supply is working, turn off the game and re-connect If grounding the right leg of any MPS-A13 transistor does Because of these issues with EOS switches, they are by far the biggest problem Any weird problems with high score and the 5101 RAM is sound that low, but compared to the orange 100 volt plasma displays used by Williams light a CPU controlled lamp, but the lamp refused to board with alcohol, and allow it to air dry. more. Corrosion opens the pores transistors. lamp sockets (use the game's metal coin door for ground.) a game to do very strange things. The molded plastic flipper link used on earlier System 1 games had a With the other end momentarily touch Z9 pin 1. strobe1 to return0. want your System1 game to work reliably, YOU MUST RE-PIN ALL THE LED needs the 150 ohm resistor as a load, and the -12 volts needs the 560 ohm If a strobe is seen through a return, the cross of those This will tell you if any one particular display is a problem.

The first step is to modify the original "mandatory" ground mod. this voltage to 12 volts DC. of case the bridge is in. Locked-on or Not Working Coil section The game may not even boot, via the driver transistor and attaches to the coil lug with the non-banded and J3 pin5 (ground) connector pins. a 5101 RAM (at Z22), which maintained power using a NiCad "Data Sentry" If this is the case, we can now tests (11/12), diagnostic #13 will engage. for this is at the C16 capacitor (top most cap next to the One of the switch blades (This assumes the J6 connector is in good shape, and the coin door slam switch is closed.) attach an alligator clip to +5 volts (the positive/upper lead Output voltage is adjustable For example when the "15" drop target falls, the above MPS-A13 Transistor Test (driver board locations Q5-Q24, Q33-Q44).
