1 | Motor does not | Check the voltage at connector (J8) on the engine |
| work. | board. At pins 1, 2, 3, and 4 with the power on. |
| Bat Wings do not | There should be approximately +34 V dc on each |
| move. | pin to ground. If the voltage is incorrect, replace |
|
| the engine board. If the voltage is correct, |
|
| disconnect (J8) and check between pins 2 and 4 |
|
| on the connector for approximately 7.5 ohms. If |
|
| the reading is incorrect, check the continuity |
|
| between pins 2 and 4 to the motor case. If |
|
| continuity exists, replace the cam system motor. |
|
| To check the sensor, check connector (J8) at pin 5 |
|
| for approximately +4.9 volts. If voltage is incorrect, |
|
| replace the engine board. If the voltage is correct, |
|
| disconnect (J8) from the engine board and check |
|
| for an ohm reading of 6.95 between pins 5 and 7. |
|
| If the reading is not correct, replace the sensor. |
|
| Note: If a short exists in the cam system motor, |
|
| damage to the engine board drivers and power |
