Fix Difficulty
|
Balls : Magnetized |
Run Super Charger Test in Test Menu with New Balls |
Replace Balls |
Very Easy |
Loop : Dirty |
Feel the inside of the Super Charger Loop… |
If the inside of the loop is rough then sand the inside of the loop with 1600 grit sand paper and Novus 2 for lubrication or if the dirt or roughness is not that bad just use Novus 2 or any stainless steel metal polish. |
Very Easy |
Diverter : Loose |
Feel is diverter moves once engaged |
Tighten diverter if the diverter rivets or screws are loose then just replace the divert. |
Easy |
Magnet Coils : Damaged |
Test Resistance from the plug on the coil with a multi meter, it should read 3-5 Ohms |
If multi meter does not generate any reading then check wiring from plug to coil.
If Coils read below 3 then replace the coils. |
Medium |
Opto : Not Functioning |
Open Switch Test of the SC Test in the Test Menu and roll a ball around the loop which will indicate when the switch is open when the ball interrupts the beam between the Transmitter and the Receiver of the 4 Opto Switched (3 by the Magnets and 1 just after the first turn in the loop after the magnet coils |
See the more detailed Opto Issues Below in order |
Easy to Medium |
Opto’s : Dirty Opto Transmitter (Often White housing) or Receiver (Often Black housing) |
Opto fail the switch test or registers intermittently |
Clean Opto Transmitter & Receiver with Cotton Bud / QTip and Window Cleaner fluid like Windex |
Easy |
Opto : Connector or wire from CPU board issues |
With game off check do continuity test with multi meter from solder joints on Opto boards back to the CPU board connector.
With the game on measure voltage on the Solder Joints of Transmitter or Receiver, which should read ~12V.
Note : Receiver will only read ~12V if it is receiving light from Transmitter…. |
Replace faulty wire or connector |
Medium |
Optos : Misaligned |
While in Switch Test loosen the screws securing the transmitter and receiver and twist them back and forth (sometimes easier to unscrew the transmitter mini opto board and place it in front of the receiver) to see if the Switch Test registers the Opto as the beam from the Transmitter makes it to the Receiver |
If it registers just realign Opto’s and ensure they are screwed in tight to stop them moving and becoming misaligned again |
Easy |
Optos : Damaged Solder Joint on Transmitter or Receiver |
Opto has been cleaned and continuity & voltage has been tested |
Re-flow the solder joints of both legs on the back of the mini Opto circuit boards of both the Transmitter and Receiver |
Medium |
Optos : Damaged Opto Transmitter or Receiver components |
Transmitter opto (Often White housing) can be tested by taking a picture of the transmitter while the game is on with digital camera or camera phone. If the Transmitter is working the picture will show purple glow.
Receiver opto (Often Black housing) can be tested by putting the machine into Switch Test and while blocking the Transmitter opto beam and then shining a strong incandescent torch/flashlight (most LED flashlight will not work) into the receiver opto.
The switch in test should show a change in the state of the Opto switch. |
Replace the Transmitter LED
Replace the Receiver component |
Medium |
Driver Board : Connector J122 & J8 Plugs damaged |
Check the continuity from the connectors of J122 (Pins 1, 2 & 4) & J8 (Pins 1,4 & 2) |
Replace damaged plugs |
Medium |
Accelerator Board : Connector Pins Damaged |
Once you have confirmed there is no issue with the connectivity between plugs J122 (Pins 1, 2 & 4) & J8 (Pins 1,4 & 2)
Check continuity with the connectors plugged in to the respective traces on the back of the Driver & Accelerator Boards |
First try re-soldering or re-flowing solder on Pins on Driver & Accelerator Boards
If pins are damaged or corroded replace the Pins on the Driver & Accelerator Boards |
Medium |
Driver Board : Fuse Blown |
Check F103 to see if it has blown |
Replace blown fuse |
Easy |
Driver Board : Blown Transistor |
Test (TIP102) Transistors Q26, Q24 & Q20
Using the Multi Meter set to Diode check place the the black lead on the center leg (or top lug) of the transistor check the reading when the red lead is placed on each of the outer legs.
The reading should be between 0.5 and 0.7. If the reading is outside this range the transistor is faulty. |

Accelerator Board : Blown Transistor |
Test (TIP102) Transistors Q2, Q5 & Q8
Using the Multi Meter set to Diode check place the the BLACK lead on the center leg (or top lug) of the transistor check the reading when the RED lead is placed on each of the outer legs.
The reading should be between 0.5 and 0.7. If the reading is outside this range the transistor is faulty.
Test (TIP-36C) Transistors Q3, Q6 & Q9
Using the Multi Meter set to Diode check place the the RED lead on the center leg (or top lug) of the transistor check the reading when the BLACK lead is placed on each of the outer legs.
The reading should be between 0.5 and 0.7. If the reading is outside this range the transistor is faulty. |
