12.1.13. Screen wiper electric motor
Presence of tension on the electric motor
| When giving tension on a conclusion 5 (weight – a conclusion 4) the electric motor has to rotate with a small speed, and at a zapityvaniye of a conclusion 3 – with high speed. |
Check
Prevention
At too reduced speed of brushes check a condition of the battery. If the battery is charged, then remove the electric motor of a screen wiper and check by hand freedom of movement of brushes. If necessary grease all hinged connections or repair. If this measure does not yield result, then check a condition of contacts, especially connections with weight. If all connections in the normal state, then the electric motor replace.
If the screen wiper does not work, then check a safety lock. If the safety lock is serviceable, then connect the electric motor to weight a separate crossing point. If the electric motor turns on, then repair connection with weight. Otherwise include a screen wiper and disconnect the electric motor socket.
Check presence of tension on the electric motor (see rice. Presence of tension on the electric motor). If tension is, then check the electric motor, having connected it to the battery through a thin delay. If the electric motor turns on, then check freedom of movement of draft. Otherwise replace the electric motor. In the absence of tension on the electric motor check tension on the switch. If there is no tension on the switch, then check conducting from a safety lock to the switch. If conducting is correct, then the switch is faulty.
If brushes work only at one speed, then check conducting and a chain between electric motor conclusions. If conducting is correct replace the switch.
If the frequency of work of brushes is not regulated, then check conducting between the electric motor and the switch. If conducting is correct, then replace the regulator.
If brushes do not come back to the parked situation at switching off, then check tension on the electric motor at the included ignition and the switched-off cleaner. If tension is, then the trailer switch in the electric motor is faulty. Replace the electric motor. If there is no tension, then check and repair conducting between a safety lock and the electric motor.
If brushes continue to work until ignition is switched off, then disconnect the socket from the switch. If brushes stop, then replace the switch. Otherwise the trailer switch in the electric motor is faulty. Replace the electric motor.
If brushes do not reach position of the parking, then check existence of the disturbing objects and jamming of draft. If everything is all right, check conducting between the electric motor and the switch. If conducting is correct, then replace the electric motor.
