Water Temp Gauge

[Jeff Miller]

The water temp sender is on the front of the block, you might be able
to reach it from under the coach (1-wire sender, to the driver's side
of the fan drive).

The sending unit on the radiator is for low-water level.

To test the gauge, ground the wire coming from the gauge to the
sender, it should send the gauge to full-scale.
