I'd like a schematic for a 6V voltage regulator, on an 1969 Benelli (Riverside) motorcycle with a 60 watt 6v generator (DC output, not rectified AC). This is to replace the aging mechanical regulator.
The generator appears to have four stationary coils and a rotating iron/wire commutator. 6v battery with a 9 amp capacity.
It has a Bosch electrical system with a mechanical regulator. The mechanical regulator also protects from too high a current, and from the battery draining out to the system when the engine is off.
Here is a description of the mechanical regulator: "When the generator voltage is low, current flows through the field windings to ground. This increases the produced voltage. When voltage rises above 7.5, current passes through a resistor to limit the rise. If it continues to rise, the voltage coil shunts the field winding, which prevents if from flowing current. Voltage flow drops to zero then.
The current coil of the regulator measures current from the generator, and drops it if the current rises too much.
The regulator also has a circuit breaker, which is normally open until generator voltage rises above 6.5v, when it closes and opens a path from the generator to the battery, lights, etc.
When the voltage drops, the current coil opens, to prevent the battery from draining to empty via the generator."
Can you guys produce a schematic to replace the old Bosch mechanical regulator? I've scoured the internet and haven't found any diagrams.
