EGT-100 Operations & Installation Manual – Ver. 1.9 – June 5, 2003

Installation

 

 

NOTE:

 This section refers primarily to installation of probes supplied as a kit 

with the specific instrument. For installation using existing or owner supplied 
probes please see the specific probe manufacturer information. 
 
The instrument will support all grounded and ungrounded probes that meet 
the requirements listed in the Specification Section. 
 

Thermocouple / Signal Wire Junction

 

 
Where possible, plan the installation such that the junction between the 
thermocouple and signal wire takes place on the cockpit side of the firewall. If 
this is not possible ensure that the junction is in the coolest possible location 
in the engine compartment. 
 
Ensure that ALL thermocouple leads are strapped together at the junction 
point. This will further eliminate the possibility of any ground loop problems. 
 

Connection

 

 
Thermocouple leads are marked with red (negative) and yellow (positive) 
sleeves and match the corresponding red and yellow twisted pair signal 
wires. Simply snap the corresponding connections together, slide the heat 
shrink sleeve over the junction and shrink to size when installing the 
instrument. 
 
For installation of the probe end into the exhaust please see the illustration as 
below:
