|  I think it's Alistair Bell on this list make a little gizmo
|that you mount in the instrument pod and connect to the O2
|sensor that gives and continuous indication of operation of
|the O2 sensor. It not a counter, but just a series of little
|indicator lights that when operating properly moved
|rhythmically back and fourth. As long as it does, all is will
|with the O2 sensor. If not - then no ocillation. On startup
|and until the O2 sensor warms up to operating temperature, the
|lights will wander eratically, but once up to temp, it will
|oscillate. A handy gadget.
