[TR] Electronic voltage regulator

[Anthony Rhodes]

The regulator should usually have an easier time controlling a dynamo at higher RPMs than lower.  It takes less field current to get the same voltage.  

It makes me think that maybe the brushes are not keeping good contact?  I don't know for sure.  

The charging warning light comes when the dynamo is putting out sufficiently less than battery voltage to get the lamp to illuminate.  Essentially it needs to be generating well below  8 volts to get the lamp to light well and at voltage the cutout relay SHOULD have cut out the dynamo from the battery to prevent reverse current from the battery through the armature to ground.
