Red - D+
dynamo
61 Я Grey - DF
or F Field coil
Ш White - B+
battery +
30/51 Б Black - chassis The
regulator housing is connected to regulator ground (black).
Before
removing the old regulator, note which colour wire went to which connection. Remove
one of the wires from the battery before you “enter” the wiring harness.
Warning:
mounting screws may not exceed 5 mm into the regulator housing. Testing
the dynamo: Method
1: Remove the wires from the dynamo - connect F to chassis with a piece of wire
– connect a 6-12 volt bulb (or a DC voltmeter) between D and ground – run
the engine. With
the dynamo ok, the bulb should now glow (6-10 volt). Beware
of too high revs, the dynamo is not regulated
and may be damaged. Method
2: Disconnect the dynamo - connect F to ground with a piece of wire - connect D
to plus on a battery – connect dynamo chassis to battery -.
The dynamo should now run like a motor, and in the direction of the arrow
shown on the Dynamo. With
the wire F removed, it should be possible to measure 1,5-2 volt just on the
remaining magnetism alone with the engine running. (If the dynamo is not being
used for a longer period, the remaining magnetism will be lost).
