Subject: Re: Dynamo removal
Hi Edward,
Just to add to Laurence's wise words. You would not normally have a voltage regulator on your car because it has a "third brush" which activates the field. This turns the dynamo into a constant current device. There are two settings - "Winter" and "Summer". The first one is higher and typically 10 amps. The 3rd brush is moved so that with all the lights on the dynamo is just charging the battery with around 1.5 amps. With the lights off this will overcharge the battery so the summer setting trickle charges the battery.
I have modified my 2 Litre dynamo to turn it into a constant voltage type with an external solid-state regulator. This works pretty well.
I hope I have adequately explained this lot here...
