Transformer Checklist

Things to check when a lighting system fails.
Keep in mind that it is rarely a transformer failure, but switching devices, etc. that are the problem.

1. Check all breakers in the transformer. The tripped breaker indicates which run/runs the problem is on. Immediate tripping-usually a dead short, delayed tripping-usually an overload.
2. Check total lamp wattage's on the circuit.
3. Check all connections and fixtures for dead shorts.
4. Check for power to the transformer with a volt meter or test light. Check reset button on the GFI outlet and breakers in the house panel for the proper circuit.
5. Make sure timer witch is on. If this does not solve the problem, remove timer. Insert male plug into the outlet inside transformer. This by-passes the timer and indicates if the problem is the timer.
6. Cover the photocell with a cap or black electrical tape. If this does not solve the problem, remove photcell. Insert jumper plug into photocell outlet inside transformer. This by-passes the photocell and indicates if the problem is the photocell.
