Overview:
Liquid temp kits can be used to measure water temp, oil temp, trans temp, and cylinder head temp.
Part Numbers:
#8037
Liquid Temperature Monitoring Kit
#8039
Economy Liquid Temperature Monitoring Kit
#4118
Cylinder Head Temperature Kit
Installation:
If using the standard liquid temp kit, you can use the supplied compression fitting to install and adjust
the depth of the probe. Connect the supplied extension cable to the probe and run to an analog channel.
Then connect the yellow wire to the “A- WHT” and the red wire to the “A- GND” (yes, this may seem
backwards but it is the way thermocouples work). The corresponding RTD dip switch should be OFF
and the GND dip switch should be ON.
If using the cylinder head temp kit, place the probe around a cylinder head bolt or spark plug. Then
connect the supplied extension cable to the probe and run to an analog channel. Then connect the
yellow wire to the “A- WHT” and the red wire to the “A- GND” (yes, this may seem backwards but it
is the way thermocouples work)
If using the economy liquid temp kit, simply install the sensor into the engine block or other
application, and run a wire from the sensor terminal to an analog channel. Connect that wire to “A-
WHT” and the ground signal is derived from the sensor physically touching the engine or chassis
ground.
Note:
For Economy Water, both the corresponding RTD and GND dip switch should be ON
