No output because of magnet issue
You may note some results under a multi-meter inspection, but nevertheless receive no output from the dynamo hub. This condition may result from play in the magnet assembly. When you rotate your wheel, it rotates smoothly like a regular hub, but you receive no output. Please initiate your claim.
Discontinuous output due to play in the magnet assembly
You may observe a normal result when conducting a multi-meter inspection. But output from the dynamo hub is discontinuous or fluctuates. When you ride with the lamp on, light output varies between bright and twinkling. You may also notice abnormal noise from the dynamo hub. Please initiate your claim.
Play in the hub can be visually seen
Hold the opposing hub axles in one hand and agitate the hub body or flange with your other hand. Push and pull the hub body toward and way from both ends of the axle. If you notice play or movement, then please initiate your claim.
