A couple of weeks ago someone posted about a
problem with the plastic breaking on their
distributor and exposing the wires from their hall
sender.
      I would like to add one more hint about
sealing the wires, use a low temp hot melt glue
gun.  My wife just bought one and the thing is
great, it gets hot enough to melt the glue but the
glue will not melt styrofoam board, so the temp
shouldn't bother wires or the electronics inside
the distributor, feel free to correct me if I am
wrong.
     It still gets too hot for you to touch the
end, you WILL get a nasty burn but this might be
something to keep in mind for all future projects.
