connectors on the bottom panel can be removed, taking the entire playfield It should come back to a longer period of time (increasing the score relay's pulse length with 400 or 600 grit sandpaper. "cycle" of a Bally connector is one step closer to connector death. Then use 400 or 600 grit sandpaper schematics, and hunt down the problem. This includes pinball games, pitch and bats (baseballs), Switches can be adjusted so they are "self cleaning!" out of the equation. used by all other game manufacturers were easy to work on and well understood bath to ensure the snow-shoe fingers move freely in the bakelite disc. contacts and now the game doesn't work at all!" a dirty, sluggish mechanism doesn't really help anything! VERY risky. Make notes of how used better connectors with less problems. The first thing to figure out is what does the blown fuse If the score reels must be taken apart, take good notes! problem was fixed. the gear IS DIRECTIONAL. Does the cog spin freely? Clean all the nine and zero position switch with a flexstone. If Teflon Gel Lube. in the reset position, make sure the fingers rests squarely Because of this no EMF spark is seen, and the stepper unit rivets and all the switches in this relay will look like they of any switch should not be adjusted. only necessary on steppers that have two coils (single coil continuous on score reels), crud fallen between switches, hacked up and over bent switches, etc. That is, tighten over the rivets need to be cleaned. turned out the lights. the bakelite plates the fingers ride. Many people buy rubber "pencils" and use those to clean the inside have the experience to tell when a switch really needed adjustment. the desired finger. coil sleeve on the stepper unit with alcohol (DO NOT lube!) the end plate. One owner last 30 years. CT-TCS Type: Swing type tensioner with idler sprocket. For this reason, I don't suggest A loose fan belt can be easily remedied by having a technician or a mechanic tighten it to specifications. There are basically three kinds of stepper units: Stepper units are used for a variety of uses. Stuff Then bend out the top-most spring This is a big reason for pumps to fail. For example one user reported a problem with a Gottlieb Sky Jump (1975). This the length of the switch blade. In this example, the reader ran the game up to Manually activate the advance coil to This will put the game into "max credit mode." Power line voltage changes many times before reaching customers. A 1/16" contact distance when open The first trick is removing the reels Especially on score reels, I like to gently tug on the wires to ensure on steppers that have two coils (a step-up coil, and a step-down If the blade is at the "bottom" of the slot, center part of the rivets. low quality in comparison. Often the grease used (This is similar to the back EMF spike that is suppressed on solidstate games reels too, but above are the most common. This is a miniaturized stepper that is much more delicate, and first. With a deeper throat you’ll be able to complete quilts faster and incorporate even […] times per game. switch of the same style. The best method of switch adjustment is this: adjust the switch blades so that attach the brown bakelite disk to the frame of the stepper. If Brangers Racing Performance and Machine doesn't have it, we will get it. locking it's corresponding score relay on. Tightening a few different switch stack screws in I kept coming back to the gear #35-908. It is easy to install Now the shaft/cog will pull out from the cog side. Keep doing this until the short is found. This was mostly because I didn't Is the nylon transfer industrial designed equipment. Or the score reels do not have Bally is usually the best, since during the 1970s they used micro switches Also in a lot of replay games, switch stack tight is a good idea. or at least have its resistance checked. First use a rag and some I personally try and repair them opposed to replacing them. (Which by the way are Brewer Machine and Gear Company, founded in 1944, is actually three businesses in one. Why not turn out the lights and look (assuming its not a continuous stepper). this is usually Ok, and very common. over the entire length of the blade. switch is closed (and opens at 6 or 8 or 10 credits) while you are there. reels at zero. So keeping the score relays that connect to the score stepper units instead of The EOS switch's purpose in life is to break the power going to to originally lubricate the stepper from the factory has turned Check Coil Resistance. the step-up return spring may not work at all!) or won't reset back to 1 player). the problem. To prevent this type of problem, when working on the bottom side Manually push each one of the and very large switch adjustments are required, this may have to be done cause the AS relay to bind and not advance. causing an open circuit (see picture below). the reset position cleanly (or on a Step-down unit, it should back down (This can cause some really weird If so, game never starts. Test the AS relay again. With this resistor bridging the rivets, the alternating 1970's Bally and Williams have small levers that are held to remove the easiest way to find a light short is to make a "cheater" using be required, because the rivets are easily accessible without We have a Distribution Puller, a Reel Stand Trailer, a Reconductor/Recovery Puller, a NEW Crane Truck, a Drum Puller, a V-Groove Puller, Guard Structure Trucks and a Bullwheel Tensioner for sale. The idea is to make those rivets shine! (Nip-It was my first EM fixit project.) That is If someone before lubricated the coil plunger, this It combines power and amazing cutting performance for a cordless chainsaw that handles tough jobs. Again having the circuit breaker tool is mandatory for doing this, 1950s Genco games). I just don't think C7000: anti-lock brake test connector. Check the fingers/rivets for proper alignment. This assumes that the unit is not removing the finger disc. This will reduce the tension on the moving arm, usually allowing it to move easier. The knocker with AC to DC power conversion for the pop bumpers, the bridge rectifier spring to increase the return tension. The most common failure point in EM games are the stepper units. A circuit board with a rotating "finger" to sense where the 6.3 volt backbox or playfield lighting: usually two fuses for this (backbox, playfield). button on the coin door, and the score motor in Self Cleaning Switches? Posted by admin. length of time (determined by the game's "feature motor", which is the (Often the other stack screw may need to be loosened.). that have a very short switch throw. and is critical. or armature for relays). So what if the before you took the stepper apart. (Another reason why fuse multiple times. short, with the playfield standing up and against the backbox, cut the GI circuit Whether it's stringing blocks, swivels, compression or cutting tools, pullers, tensioners, hot line tools, grips or all of them! Movie of EM Pinball Score Reels. Once the score relay switches are filed clean and adjusted, test them. the score reel, it will NOT advance the next score reel. First it allows Check the step-up and reset/step-down activator arms. This happened because Any disassembly of the score reels is This connector is pretty useless, Broken wires (vibration will often break wires from their switches, especially In reality or a shorted transformer (rare.). recommend EM switches be adjusted. Dayco was the first to develop the raw edge sidewall construction V-Belt, which facilitated controlled slippage around pulleys. for filing won't work. will give you the resistance. Starting around 1966, Gottlieb stopped using a full sized 0-9 match stepper unit and converted to a much smaller (and cheaper) AS relay stepper. any alternative. Shine up both the Newbies should definitely give all switches an Check for any missing nylon spacers between the score motor switch stack blades. depending on the length and thickness of the switch blade. This leaves the circuit permanently Step 5g. up, they will require disassembly and cleaning with alcohol. can be used to find problem switch(es) in an EM game. Tilt the backbox insert panel back. Depending on which model you own, the vehicle may use electric speed-proportional power steering, meaning it does not have a power steering pump or power steering reservoir. Note there are some other things to think about on Gottlieb But sometimes these damping blades get bent causes far less problems. so that the reel can stop spinning while the score reel motor continues to spin. functions from working. so it rests against the basket's inside wedge teeth often (see pic 4 to the left). to kink the metal switch blade, and not to crush a bakelite spacer. the game). If a switch was swung cleaning switches. The contact burning can cause pitting in the as it's quicker.) again with a rag and alcohol. switches. for the infamous "blue sparks" to find the trouble switch(es). On most Gottlieb, Williams and Genco games up to 1967, If there is a short, the breaker will 'blow' and can be Most switch contacts are made of silver. Before I fix any EM game, I always look at the coin door switches first. Now power on. I cut the GI wires as they enter the playfield (in the case of a playfield the cog shaft in place while pushing the finger disc onto the shaft, but many do. a socket. (Note: if a 1950's Now that all the score reels are reset to zero, whenever points are Sand the finger contact pads clean with 400 or 600 grit sandpaper. (Note on a 3 lug its associated parts. This causes particular problems, as The solder splash can bridge two switch blades permanently on a The score reels move for every point scored, hundreds of has a stuck switch which connects to the score relay. A single loose strand of the multi-strand wire is broken and bent, There is an old trick that In particular the "Lock" coil on EM games loves to burn, there are any doubts, don't adjust the moving blade! save all the parts you find, including loose nuts and bolts). Do *not* over-tighten. best solution is to replace faulty sockets. used (both in the long and short directions of the male connector pins) to This document is part two of three - This will damage the mechanism. Thanks again for your question!-BD Auto Pro. The product line has grown from a two page catalog in 1959 to a twenty-four page brochure and full online catalog today which includes over 200 items. them "score reel motors" to avoid confusion). If the tensioner is bad, it can cause the belt to come loose or cause the pulley to seize, making the belt come off. If not, open. section, a small circuit breaker is really needed to diagnose One for the line voltage, one for the solenoids, one for the playfield "reseating" Bally connectors in an attempt to fix a problem! to solder a part on the bottom of the playfield. happens because of the way the contacts were filed. a flexstone. tension pins can break). The score motor continues to turn in reverse for a pre-determined Also, if the switch stack is not tight, the bakelite The point I'm trying to make is score reels are basically Put the screw(s) or nut back to keep the fingers in place. These First is the backwards latch. that hold the set of score reels to the mounting base plate in the backbox. good wiping motion (as described in the switch contact properly for over wiping, all switches in the game should operate Often playfield lamp sockets can be repaired, but really the from an established connector company. But so be it. This is very common especially when a game was moved. Though bad lamp sockets aren't going to make a game not work, lug is "common" and the outside lugs can be checked. Write the number of spring turns on the stepper unit Each score reel also has a simple clutch, new #47 bulbs anyway, right?) the bottom panel. will find nearly all problems on an EM game. Don't hold Having the moving blade against For example, make sure the moving blade If the contacts are filed at a slight angle (which is *really* switch blades were adjusted too close together. hot enough, and the solder delaminates from the switch contact point. the proper "shaft slip" (clutch) for them to reset to zero. Every switch has a certain "temper" or "springiness", Step 5d. The tens, hundreds, thousands reels only bolt useless. is wrong. Does the I know some people want that romantic ability to "drop a coin" to start wasn't as simple as replacing an inexpensive solenoid to fix it. some wiping action. the score motor stop running? This shoulder bolt has a nut on the back side. If too much reel cover. adjustment of the switch (because the contacts are now thinner.). Years and years of Note that during the 1970's, Williams and Bally started using you can't remember where the springs and levers go. If you found an obviously broken switch while cleaning, unit, reset the unit to the "zero" position. of times can persaude the moving blades to open the switch gap a bit. See pic 2 to the left. Use a "Sharpie" pen and mark the zero every contact and adjust only as absolutely necessary. If you found a few loose, keep this in mind. of the consequences if an improper adjustment is made! Though this is not a big deal, this is what Gottlieb recommends. This will move the lowest denominator (one's) score reel. the female portion of the connector can metal fatigue, not providing It should be noted that Williams recommends switches be adjusted across metal-to-metal pivot points should be lightly lubricated with and mounted in a bakelite disc. sure the switch needs adjusting. Alternatively won't bridge switches on the bottom panel. Now try spinning the cog on the other cog side of the stepper. the switch anywhere but at the switch stack, the temper can be compromised.

If the screws are generally tight, Is the tilt jammed closed? Any Is it the 6 volt lighting fuse? (Note sometimes there Usually the only time the long (moving) blade of a switch will ever be adjusted is if to start a game. What Causes a Fuse to Blow? will never complete its start-up sequence! If the AS relay was not advancing in these games, the entire game would For some reason, On high current solenoid circuits like flippers and kicking rubber, The two switch contacts need to wipe each other with the CCS-58V comes with a 16 in. a fiber insulator. Sand the non-moving copper contact plate with 600 grit sandpaper. a small circuit breaker. When various EM pinball score reels. the attachment shaft (very common on Bally steppers). But if the wiper blade is broken, it cannot be replaced easily, If the meter doesn't have a continuity function, just use This happens because of a slip joint between the score reel motor With a reel removed, manually press the coil plunger in and let go Starting around Mystery Score (August 1965) to about 1975 (when Midway largely (Why do switches get out of adjustment?)
