Toplight 2C Power and Connection Issues

Verify the integrity of the external power path to the light. Confirm this symptom by inspecting the spade connectors at the rear of the unit for physical detachment or corrosion, and by checking the continuity of the cable leading from the dynamo or headlight. On systems with polarity-sensitive wiring, confirm the issue by swapping the positive and ground connections to see if the light activates.
