Welcome to the forum. Voltage to your headlamps is hot all the time. Your headlamps are controlled on the ground circuit. If you haven't already, use a testlite at the left and right headlamp fuse, that circuit should be hot all the time. You can also check for voltage at the headlamp connector, low beam circuit, orange with black tracer, should be hot all the time. The ground is through the dimmer switch.
My info didn't exactly show a circuit breaker. I know on older systems, the breaker is inside the headlamp switch assembly, the breaker itself isn't replaceable as far as I know.
