Help with no headlights. 1974 scamp. Blinkers come on instead...

Maybe this will help.
This is a general scheme of the some of the wiring including the two feeds to the headlight switch for the headlights.
B1 is the terminal for headlights. Just the headlights. There is a 15 amp circuit breaker in the switch.
B2 is the terminal for the power to feed the parking lights, etc.

(insulation colors, wires sizes, etc, vary depending on year and specific options.)
