I made my own reply
AutoChoke
It seems that the resistor with the automatic choke has the function of increasing the rise time.
Since it is powered by alternating current, it may be possible to put a diode instead of the resistor?
Like this, It will be powered only during one alternance and the voltage is halved ?
Yes its possible and a diode like 1N4001 to 1N4006 will fit well
But putting a CTN will be better because the enricher can work quickly when temp is hot
instead of working all the time
Headlight
The resistor is only used when no lights are powered
Is the resistor serves to protect the generator coil against high voltage in this case of no lights powered?
So the resistor is for protecting people against touching wire when the motor is running and no lights are on
In this case the current can reach up to 100V and can be very dangerous for some people
The alternator is 1000V protected and nothing damage to it with no resistor
Nice day to all
