As far as the headlamp circuit breaker, it gets voltage from the fusible link. The fusible links appears to get voltage from starter solenoid battery terminal. Follow the circuit from solenoid battery terminal and check voltage. Of course the battery cable at solenoid has to have voltage. One way to check fusible link, check for voltage on both sides of link, if voltage on one side of fusible link and not the other, the fusible link is faulty.
Make sure battery has a full charge and battery connections are good.
