Keith: That is exactly what is wrong. You have verified it by
measuring 12v at the switch. The circuit works when there is no oil
pressure and then the switch goes to ground through the engine case.
Obviously, your switch isn't closing. Pull the wire off and stick it to

the engine or head. I'll bet it lights right up then. Go get a switch.

They are absolutely notorious for failures. Five dead switches (maybe
more) for every bike that actually has a pressure failure.
