Answer / carl_ellis

If the lamp lights when the wire from lamp to the sending
unit is grounded, then the other side of the lamp has
power. The circuit is designed for the lamp to light when
the sending unit provides a complete electrical circuit.

The lamp lighting proves that
- the bulb is good
- there is power at the lamp.

If the warning lamp does not light when it should, then the
sending unit is faulty.
