flasher lights now work, the flasher unit is defective and must be renewed.
If the lights do not work the relay is defective and must be renewed.
The length of time the flasher is operating can be altered by screwing up the adjusting screw located in
the small boss at the back of the time switch. Screw in to lengthen the time of operation and out to
shorten the period.
N.13 THE WINDSHIELD WIPER
Normally the windshield wiper will not require any servicing apart from the occasional renewal of the
rubber blades.
Should any trouble be experienced, first check for loose connections, worn insulation, etc., before
dismantling the motor.
1. To detach the cable rack from the motor and gearbox
a) Unscrew the pipe union nut.
b) Remove the gearbox cover.
c) Remove the split pin and washer from the crankpin and final gear wheel.
d) Lift off the connecting link.
2.
Commutator dirty
Remove the connecting leads to the terminals and withdraw the three screws securing the cover at the
commutator end. Lift of the cover. Clean the commutator with a cloth moistened with petrol (gasoline)
and carefully remove any carbon dust from between the commutator segments.
3.
Brush lever stiff or brushes not bearing on commutator
Check that the brushes bear freely on the commutator. If they are loose and do not make contact, a
replacement tension spring is necessary. The brush levers must be free on their pivots. If they are stiff
they should be freed by working them backwards and forwards by hand and by applying a trace of thin
machine oil. Packing shims are fitted beneath the legs of the brush to ensure that the brushes are
central and that there is no possibility of the brush boxes fouling the commutator. If the brushes are
considerably worn they must be replaced by new ones.
