Troubleshooting Guide: 12 Volt Pendant Lighting
Part 2. If all Open circuit or Short circuit conditions have been checked for and corrected as shown in Part 1, but still the
system does not turn on, continue with the following:
Determine if the Transformer is working. The transformer output is high frequency and cannot be detected by most
multi-meters. A simple Lamp test can verify the status of the Transformer.
Caution: Have a qualified person perform this operation. Do not hold lamp with bare hands as lamp heats quickly and
may cause injury. Hold the lamp carefully using insulated pliers.
Turn off power and remove Bi-Pin Lamp from socket Assembly. Examine Lamp to verify that it does not appear defec-
tive. Lamp Glass should not be darkened and the filament should be intact.
Expose Transformer by removing canopy and then turn power back on. These 12 Volt pendants are supplied with a
Class 2 (power limited) Low Voltage Transformer, so there is no potential for shock. Carefully touch each one of the
Transformer’s 12 Volt output wires to each pin of the Lamp as shown in Figure 4. If the Lamp lights, this indicates a good
Transformer and the Pendant lead needs to be replaced. If the Lamp does not light, then the Transformer needs to be
replaced. Turn off the power.
Part 3. List of Troubleshooting Issues and Solutions for 12 Volt Pendant Lighting

Diagnosis: Deteriorating 12 Volt connections due to high current.
Corrective action: Recheck all secondary connections, looking for discoloration, oxidation or hot spots.
Tighten any loose connections. Replace Pendant leads if contacts are discolored.
Problem: Circuit Breaker on main panel trips on initial power up:
