Gugie, have you seen any electrical testing? Specs on the SA hubs are 6 volts 0.3 watts. I don't have a good handle on the power required for, say, a Luxos.
For an SA hub condition is a crap shoot due to age, but they are mainly bearings and wire. Wire generally fails open, rather than petering out in a slowly degrading failure mode.
