| SYMPTOM | CAUSE |
| REQUIRED ACTION |
|
|
|
|
|
|
|
|
| With VGM power on, check airflow near each |
• | Sloppy, unpredictable or | Blocked or faulty fan |
| computer fan. Case cooling fans are intake fans. |
| ineffective steering |
|
| Power supply fan is exhaust fan. Assure that |
|
|
|
| nothing blocks airflow. |
• Video appears on screen |
|
| Turn off VGM power. Open dashboard. Support | |
|
| Faulty mechanical |
| steering wheel and remove outer mounting |
• VGM (video game machine) | parts |
| screws. Remove metal shield (if your VGM has | |
| starts normally |
|
| one) over motor. Inspect for faulty or worn belts, |
|
|
|
| bearings, couplings, gears, etc. |
|
|
| 1. | Inspect Wheel Driver Board under |
|
| Faulty Wheel Driver |
| conditions. LEDs glow if motor driver circuits |
|
| Board |
| receive AC power from transformer. (Voltages or |
|
|
|
| signals may or may not be normal.) |
|
|
| 2. | Examine fuses and cables on Wheel Driver |
|
|
|
| Board. Replace bad fuses. Using digital |
|
|
|
| voltmeter, verify AC voltage between each fuse |
|
|
|
| holder and ground. You should measure |
|
|
|
| approximately 25V. See Wiring Diagram. |
|
|
| 3. | Using 20 VAC setting on digital voltmeter, |
|
|
|
| measure DC voltage at motor. Don’t move |
|
|
|
| steering wheel, drive belt, or motor while making |
|
|
|
| this measurement. Any reading indicates |
|
|
|
| unstable supply that may contain ripple or noise. |
|
|
| 4. | Verify proper operation of Wheel Driver Board by |
|
|
|
| placing it in working VGM. |
|
|
| 1. | Turn off VGM power. Open dashboard. Support |
|
| Loose or worn drive |
| steering wheel and remove outer mounting |
|
| belt |
| screws. Remove metal shield (if your VGM has |
|
|
|
| one) over motor. Inspect for faulty or worn belts, |
|
|
|
| bearings, couplings, gears, etc. |
|
|
| 2. | If drive belt isn’t worn or damaged, check its |
|
|
|
| tightness. |
|
|
| 1. | From Diagnostics Menu, choose FORCE |
• | No wheel feedback | Improperly set |
| FEEDBACK ADJUSTMENT. |
|
| feedback | 2. | Set feedback to match player requirements. |
• Steering aims vehicle as |
|
| Maximum force may be too extreme for very | |
| expected |
|
| young or inexperienced customers. |
|
|
| 1. | Examine fuses and cables on Wheel Driver |
|
| Faulty circuit |
| Board. |
|
|
| 2. | Check cables and wiring between computer, |
|
|
|
| interface, driver and motor. |
|
|
| 3. | Check resistance of motor series resistors |
|
|
| 4. | Replace bad parts. |
|
|
| 1. | Turn off VGM power. Open dashboard. Support |
|
| Faulty motor |
| steering wheel and remove outer mounting |
|
|
|
| screws. |
|
|
| 2. | Remove metal shield (if you VGM has one) over |
|
|
|
| motor. |
|
|
| 3. | Unscrew caps. |
|
|
| 4. | Inspect motor brushes. Replace worn parts. |
