Dynamo Lights

Have another test for the hub, found on another forum:

Use the multimeter on resistance and without turning the wheel check for a reading across the two hub terminals. This should be very low, mine measures 2.5 ohms. This is the coil of the generator. If there is no reading then the rotation has severed a connection internally, the coil wires will be very thin.

So hopefully this confirms it one way or the other!
