- Rectifier
- Battery
- Coil
- Contact Breaker
- Horn
Stator:
- Produces electricity
- As the motorcycle runs, a magnetic wheel spins and induces electricity in coils in the stator
- As the cam spins faster, the induced current increases linearly
Points:
•The points ignite the fuel when the engine is approaching top dead center
•The capacitor is charged via the battery.
•The points timing is controlled by centripetal force.
•As the cam spins faster two weights on spring spread apart. This forces the spark to occur sooner in the cycle
Rectifier:
- The Rectifier converts AC to DC to charge the battery and run electrical components like the lights and horn
Horn:
- The horn was broken
- Most likely causes: the timing screw came off and pieces inside got stuck
- To repair we had to drill out the rivets and reassemble the inside
- Now it works!
- Piston is a permanent magnet
- Current runs through horn and creates magnetic field in coil
- Piston is pulled down and separates points
- Piston is pulled up by the drum acting a spring
- Points pushed back together
