A-Reg Alternator Regulator
HOME
We
now have a new range of Regulator/Rectifiers for use with Lucas type
permanent magnet (RM) alternators. These units replace the traditional
bridge rectifier we have had since the late 1950s and the Zener diode
(12V usage). In some cases of high-output alternators you might have
been using two Lucas Zeners (Norton Commando MKIII) or a matched pair
of Zeners (3 phase) or a triple Zener unit (Triumph)
A Reg 1, 12V 200W capability.
A Reg 6, for 6V 200W capability.
A Reg 3, for 3 phase 200W capability.
Polarity:-These units can be wired Positive or Negative Earth to the
motorcycle. It is essential that the Positive and Negative output of these units meets
the battery Positive and Negative exactly the same.
All three units have the same dimensions is 60 X 66 X 25mm with 6mm fixing holes at 55mm. Unit is best
fitted to a flat metal surface (can be painted) as a basic heat sink.
Connections are similar in that the YELLOW wires go to the alternator
while the battery wires are the traditional RED + and BLACK -
Full instructions come with each unit.
They can be used without a battery but it is advised to use a
Capacitor, (We can supply) especially if you have coil/electronic
ignition (not essential if using magneto ignition) Be aware that with a
stalled engine you no longer have lights, horn or stop light.
Batteries:- I have always advised that the minimum capacity should be
5Ahr for any Classic British Motorcycle using traditional Lead Acid.
Modern AGM batteries would appear to be acceptable.
Cyclon cells of 5Ahr or more are also usable.
What is not suitable is the 'square' 'dryfit' type with spade terminals
(often surplus from burglar alarms). These will overcharge in due
course and dry out.
