INSTALLATION GUIDE
PROFESSIONAL STEPPER-MOTOR
ANALOGUE ExhAUST GAS TEMPERATURE
GAUGE
2650-1293-00
Important
Exhaust Gas Temperature gauges (Pyrometers) are sensitive, high accuracy instruments. They must be handled and installed
with care to insure proper performance. Carefully read and follow these instructions, and your exhaust gas temperature gauge will
provide you with a long and accurate life.
Wear Safety glasses and disconnect the battery
before making any electrical connections.
As a safety precaution, the +12V terminal of this product
should be fused before connecting to the 12V ignition
switch. We recommend using a 1 Amp, 3AG fast-acting
type cartridge fuse.
NOTE: When the ignition is off the pointer may not always rest at zero.
Installation
1. Check that you have all parts required for installation, and the engine is cool.
2. Disconnect the negative (-) battery cable.
