We have a great deal of experience in 12 volt conversions for dynamos. For trouble free 6 or 12 volt operation with good output and without causing the armature to over-heat we recommend our UK made, solid state regulators for positive or negative earth machines. These can be swapped from 6 to 12 volts so you only need to chose the correct earth polarity.
