[ORRando] misbehaving SON generator hub

[Bill Gobie]

You could try holding an AC voltmeter's probes against the connections  
on the hub (with the light still connected and turned on) to see if it  
puts out 6 volts as you spin the wheel by hand. Or borrow another  
light and see what happens.

Odds are hub has failed. Hopefully yours is one of the versions that  
does not require cutting the spokes to service the hub. Also hopefully  
it is still under warranty.

Send it to Peter White. He should have it back to you real quick. Note  
even if it is under warranty you will have to pay for a wheel build if  
it has to be cut out of the wheel.

I have had two SONs' bearings fail.
