REFLECTOR: engine probes

[Sid Knox]

Fact:  The thermocouple probes are low impedance (low source resistance), 
low voltage generators (type J for CHT, type K for EGT).

Opinion: Modern engine analysis systems will typically have high impedance 
inputs for the probes.  One probe should successfully drive several of these 
loads.
