Power Probe ECT 2000 - Manual (Page 7)

After connecting the SMART transmitter’s 20 ft. power lead to the vehicle’s battery, a signal is generated through the green signal wire and ba-
nana plug. This is connected to the circuit you want to trace. The signal will radiate along the circuit, which you can detect by using the SMART
receiver. There are two types of circuit signals that the SMART transmitter generates. They are the Grounded Circuit SIGNAL and the OPEN
CIRCUIT SIGNAL.
It is very important to familiarize yourself with both of these signals and how they work in your circuit. The “Grounded Circuit signal” and the
“open circuit signal” are different from each other, which you should understand. (See: “Characteristics of the Short/Grounded Circuit Signal”
pg.. 8 and “Characteristics of the Open Circuit Signal” pg. 9&10)
The 2 main features of the ECT2000 is that it transmits a signal into a circuit with the SMART transmitter and then you trace it with the
SMART receiver . The easiest way to insure that you are following the problem circuit is to isolate it from other parallel circuits.
