Locate your circuit breaker. Examine the breaker and look for tripped switches. A tripped circuit breaker switch will appear to be in the “off” position when it was previously in the “on” position.
Unplug or turn off all electrical components attached to the outdoor lighting circuit breaker switch.
Reset the circuit breaker by flipping the switch to the “on” position. If the breaker successfully resets, which means if it does not return to the “off” position, the short is in one of the lighting elements you unplugged. However, if the breaker trips after all fixtures have been unplugged, the short is in the electrical wiring.
