Head Light, Horn & Speedo Light Circuit
with 5 wire Bosch Magneto/Generator
RH Brake Light Switch Switch is a NO type (normally open) in it's relaxed state (Position when brake lever is squeezed)
The headlight, horn and speedo light circuit receives it's voltage from the single yellow wire coming out of the magneto assy. Power is directed to the terminal block and then up to the horn which pigtails off to the light switch. When the switch is turned on, voltage is then sent up to the headlight via the Black/Yellow wire. The Black/Yellow wire also pigtails from the headlight connection and sends voltage up to the speedo bulb via a Black/Yellow wire.

The tail light circuit gets it's power from the gray wire coming out of the magneto assy. This circuit is very simple because the gray wire goes directly from the terminal block to the tail lamp. The headlight circuit must be energized for the tail light coil to function. When the headlight is turned off, the tail light will also go off.

The brake light circuit gets it's energy from the green wire coming out of the magneto assy. The green wire connects directly to the brake light at terminal block and sends power to the bulb. This power is interrupted by a grounding wire that feeds from the brake light sender switches. When the brake lever is squeezed, the ground is interrupted/removed from the circuit which allows the circuit to be energized and the light to illuminate.
The horn is energized by completing the ground circuit at the horn switch. The switch is grounded to the handlebars. When the horn button is pressed, the switch allows the purple wire from the horn to ground out thus completing the circuit.
