CLEANING AND INSPECTION OF EGT.
Unless mechanical damage is evident, broken glass, bent or broken pointer, or broken case, the following
checks should be performed before removing the instrument.
1. Remove probe and check for broken weld (at the tip end) or burnt off end. Measured resistance of
probe should be .8 ohms. Clean the connections with steel wool before reassembly.
2. Disconnect lead wires at instrument and measure. Resistance with lead wires connected to probe
should be 3.3 ohms. Clean connections with steel wool before reassembly.
3. With leads connected to instrument, heat probe with propane torch to dull red. The meter should read
up to the fourth graduation or approximately 1500°F. Before making this check, make sure that the
adjustment screw, which is located in the rear of the instrument case, is in the center of its travel. If
this screw has been turned to either end of full travel, it will shut instrument off and no indication will
be shown on the pointer. If meter still does not read. replace it.
–CAUTION –
Do not connect ohmmeter. It will burn out the movement of the
meter.
INSTALLATION OF EGT PROBE AND GAUGE
1. Install the probe and secure with locknut or clamp.
2. Route the thermocouple wires along with the existing wire harness to the instrument panel.
3. Install the EGT gauge into the instrument panel and secure with four bolts.
4. Connect the thermocouple wires to the rear of the EGT gauge.
