 Overview
This is a solid state encapsulated regulator for motorcycles using the
Lucas E3 type dynamo. The NanoControls dynamo regulator is designed to
replace the mechanical regulator with modern reliable semiconductors.
Provided the dynamo is capable of delivering enough power the regulator
can handle up to 100W (requires good cool airflow around regulator) at 6V
and even more at 12V. The regulator must be used with a good working
dynamo and automotive battery and is guaranteed, subject to correct
fitting and use.
The V-Reg II is an upgraded version of the original V-Reg. New features
include:
- Current limit to the field winding, allows excellent performance
when using a 6V dynamo on a 12V system.
- Tougher electronics, with the introduction of higher energy spark
suppression.
- Improved "thermal foldback" which progressively reduces
output power if the regulator gets too hot.
- Higher specification voltage reference.
- Better servo loop stability, with new electronics which 'predict'
when the output voltage is nearly correct and control the field
current earlier.
Voltage & Polarity
WARNING:
Ensure you fit a regulator of correct voltage and polarity
As manufactured all regulators are set to operate at 6V. For 12V
operation the small GREEN wire loop should be cut and sealed (with epoxy
or silicone). If you ordered a 12V regulator your supplier may have
already done this for you.
+ Earth regulators have a BLUE field wire.
- Earth regulators have a WHITE field wire.
For 6V operation the GREEN link wire is intact
For 12V operation the GREEN link wire is cut and sealed
Dynamo Polarising & Testing
The dynamo should be tested before connecting a new regulator:

- Check that the internal dynamo wiring is as Figure 1.
- Polarising:
To ensure the polarity of your dynamo is correctly setup for
your bike (and therefore the regulator functions correctly), it
is necessary to polarise or 'splash' the dynamo.
To do this disconnect the field (F) connection from the dynamo;
take a wire from the live terminal of the battery and briefly
touch the F terminal of the dynamo ensuring the battery is
earthed (as per intended use). This establishes the fields'
remnant magnetism which is required for correct start-up.
- Unregulated Output Test:
Remove normal D & F connections and link D and F
together, connect a 12V headlamp bulb from the linked point to
ground.
Run engine at fast idle, lamp should be bright.
If the dynamo has been dismantled or refurbished it is vital to
confirm the generated voltage polarity, use a meter to
check the voltage between earth and the D & F linked point
is the same polarity as the battery live. If the polarity is
reversed it is necessary to reverse the field connections inside
the dynamo, re-polarise and retest.
- Reconnect all circuits after test.

Fitting & Testing
To maintain original appearances this unit may be fitted inside the
original control box by first removing all of the contents (solenoids,
points and resistors) or it may be mounted in any convenient corner, maybe
in the top of a tool box, such that it has some protection from physical
damage and weather. Fixing is via a stainless steel M5 stud which is not
connected to the internal circuitry. An M5 self-locking stainless steel
nut is provided, this requires an 8mm A/F spanner (2BA may be acceptable).
Disconnect the battery before starting work. Ensure the dynamo internal
connections are as figure 1 (above). The four wires can be soldered to the
original four terminals inside the control box if used in accordance with
the adjacent wiring table or alternatively any suitable crimp connectors
can be used to connect to the bikes' wiring. Taking into account proper
practices to produce clean firm connections.
To check operation of the regulator measure the voltage across the
battery, at rest the voltage will be around 6V or 12V depending on
version, rising to around 7.25V or 14.4V once the dynamo is operating
(2500 engine revs, headlight OFF). If the unit is fitted within the
original regulator box the dynamo power handing is limited to less than
the regulators maximum due to the restricted movement of cooling air,
however it will comfortably handle the standard 60W dynamo.
This unit is only guaranteed provided it is fitted and used as
intended, any miss-connections can cause damage.
