Reply to "Blunami 3 rail AC"

Bob, project is on hiatus 'til next week.  Pickup roller assemblies are faulty, so no meaningful on-track testing can be done until they're replaced.  One had no conductivity between the roller and its pins that mate with the arm forks, the other had a voltage loss of around 2½V.  So the Blunami board wasn't getting full supply voltage when the Shark was on the track.  Others have reported pickup problems with the Weaver Sharks.
