Is the current capacity a function of the magnetic strength of the rotor magnets?
Rotor with permanent magnets rotates within a stator with 6 poles. This is used on a kick start motorcycle for starting and running the bike, no battery. Voltage of 3-10 VAC is there when I kick-start when measured to ground with ignition coil disconnected. When ignition coil is connected, no voltage and no current flow is measured.
Coil has 1.5 ohms to ground and is a 6V coil, so current should be at approx 4 amps when points open and voltage is at max.
I am thinking the magnet has lost some of its power and will not supply the needed current when a load is applied.
Any help would be appreciated.
