Testing And Polarizing The Dynamo; Troubleshooting - Dynamo Has Stopped Charging - WASSELL WW10221N Quick Start Manual

Testing and polarizing the dynamo

1
Remove the dynamo from the motorcycle
2
Connect a temporary jumper from the F terminal to dynamo earth
3
Connect a wire from negative terminal of the battery to dynamo chassis
4
Connect a wire from positive battery terminal and touch it on to the D terminal
5
The dynamo should motor in the correct drive direction ( see arrow on case )
6
This will determine if the the fi eld coil wires are connected correctly , if the armature does not rotate
in the direction of drive reverse the fi eld wires and try again
7
When you have completed the test and are confi dent the polarity and rotation is correct, connect to
the regulator as per diagram 2

TROUBLE SHOOTING
WHEN DYNAMOS ARE LEFT STANDING FOR EXTENDED PERIODS THEY CAN LOOSE
RESIDUAL MAGNETISM. TO RE NEW THIS FIELD MAGNETISM:
1
Disconnect the regulator unit
2
Connect a temporary lead between dynamo F terminal and ground
3
Connect the positive battery lead and touch to dynamo terminal D for a second
4
Re-connect your regulator. This should be suffi cient to get your dynamo charging again
