[Chevelle-list] another subject (oil light)

[Rick Schaefer]

   The oil light is looking for a ground.  It has power all the time with
the key in the on position,  and when you start the motor & get pressure,  a
switch inside the sending unit opens & takes the ground away and the light
goes out.

1- Wire from light to sending unit is shorted to ground.   Disconnect wire
at sending unit.  , if light stays ON all the time, you probably have a
short to ground between light & unit.    It COULD be the ground you added -
disconnect it and see what the light does.

2 - Bad sending unit - switch inside does not open - easy to isolate.
Disconnect the wire to the sending unit.   Lite should be OUT with key ON  -
ground the wire you disconnected from sending unit, light should go ON.

My guess that the ground you added is also grounding the oil pressure
light.
