Mike,
Interesting idea (from an electrical standpoint, assuming the oil pressure
will build from the starter and there are no other problems as discusssed on
this thread before), but one caveat! Usually the oil pressure switch drives a
low wattage light bulb. The contacts may not be rated for the current of the
coil. If you do this, I would recommend using an interposing relay, i.e., let
the switch operate the relay, and let the relay power the coil.
This setup has another interesting operation -- should you ever lose oil
pressure, the engine will shut down automatically. An especially good idea if
you let others drive your car, and some of them don't watch the gauges as they
should.
