PART NUMBER WW10221N
6 volt negative earth DC regulator
Important
- please read these instructions carefully prior to fi tting. This unit will be damaged if
connected with reverse polarity. Before connection please check your chassis earth polarity and make
sure you have the correct regulator for your earth polarity.
Please note the wiring instructions also require a 15 Amp fuse to be connected in the red wire. The
regulator will cause this fuse to blow if the battery is connected backwards. If the fuse blows, re-check
that the wiring and battery polarity are correct. Running the regulator with reverse polarity, even for a
short duration, will damage it beyond repair. If in doubt contact an expert for advice.
1
Disconnect the fi eld coil wire marked 1 from F and connect it to the D terminal
2
Disconnect fi eld wire marked 2 from earth screw and connect it to F terminal

Testing and polarizing the dynamo
(diagram 1)
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
Diagram 1 testing and polarizing
Diagram 2 negative earth wiring
TROUBLE SHOOTING
- DYNAMO HAS STOPPED CHARGING
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
