Page 6: The Smart Transmitter
Signal Lead The signal lead with the green banana jack, plugs into the assortment of adapters, probes, and clips that are provided for you in the ECT3000 kit. These accessories simplify connect- ing to your circuit. Moveable Hanger / Stand Provides multiple convenient mounting options when testing. - Page 7 8 and “Characteristics of the Open Circuit Signal” pg. 9&10) The 2 main features of the ECT3000 is that it transmits a signal into a circuit with the transmitter and then you trace it with the receiver . The easiest way to insure that you are following the problem circuit is to isolate it from other parallel circuits.

Page 8: Characteristics Of The Short/Grounded Circuit Signal
Path of Least Resistance Characteristics of the Short/Grounded Circuit Signal: 1. Strongest when flowing exclusively through one wire Major portion of signal goes When the signal is conducting through only one wire, the signal into short (ground) strength is at its maximum because 100% of the signal is travel- ing through that wire exclusively to return back to the negative side of the battery. -

Page 12: Battery Installation
Battery Installation 1. To install the batteries, carefully remove two battery covers screws, remove the battery cover on the bottom of the receiver housing and insert (2) AAA batteries into the battery compartment. Be sure the polarity of the batteries are correct then replace the battery cover. - Page 13 When the Receiver is in “pulse mode”: It detects both “grounded” and “open” circuit signals. It picks up and determines strong from weak signals by the pulse frequency rate. The sensitivity is ready to be locked in, by pressing the “Sense Lock / Sense Low” button. It detects and displays the direction to ground or a short circuit.

Page 14: Locking /Setting The Sensitivity Of Short/Grounded Circuit Signal
Locking the Sensitivity for Short/Grounded Circuits Fig. A To lock the receiver’s sensitivity for short/grounded circuits, it must be turned on and in “pulse mode”. Hold the “Open & Short Pick-Up” of the receiver parallel and as near to the wire as you can while achieving the most rapid pulse rate. (See: Fig. A) Now press the “Sense Lock/Sense Low button”. -

Page 16: How To Use The Ect3000 In Diagnosing Circuits
How to Use the in Diagnosing Circuits Connection Accessories: Included in the ECT3000 are the following connection accessories. • Alligator Clip: for connecting onto any conductor such as a wire or a terminal. • Blade Probe: for tapping into fuse socket terminals and connectors. -
Page 17: How To Trace Out A Short Circuit To Chassis Ground
How to Trace Out a Short Circuit to Chassis Ground A direct short to chassis ground that blows a fuse, is one of the simplest circuits to trace for one simple reason. The majority of the “Grounded Circuit Signal” travels THROUGH THE SHORT CIRCUIT TO CHASSIS GROUND making it easy to trace. This sometimes eliminates the need for isolating the circuit. -
Page 18: Isolate Your Circuit
Verify a Short Circuit to Ground One of the best tools for verifying a short circuit to ground is the Power Probe 1, 2, or 3. To verify a short circuit connect the Power Probe to the circuit and press the power switch forward. -
Page 19: Short Circuit Inside A Wire Harness
Short Circuit Inside a Wire Harness A common occurrence inside of wiring harnesses is that there are two wires running close and parallel to each other. One wire is the positive wire that flows one way and the ground wire that flows back the opposite direction. When the signal source runs closely parallel to the signal return, as in this case, they cancel each other and the signal strength is considerably reduced. -
Page 20: Reception Distance And What That Means
Reception Distance and What that Means. When tracing parallel circuits, you can determine if a one wire has a stronger “Ground- ed Circuit signal” present over another wire. The wire that has a stronger signal carries a larger current. This means the circuit that has the stronger signal also has a lower resistance compared to the other parallel branch. -
Page 21: Tracing Circuits That Are Shielded
Other wires can shield Wet carpet, metal, even Open circuit signals your own hand can shield Open circuit signals. Break / Open Plastic Harness Cover Wire harness probe lets you probe between the wires. Tracing Circuits that are Shielded: Quite often you will need to trace circuits in areas that are shielded from the receiver. -
Page 22: Open Circuit Signal Vs Grounded Circuit Signal
Open Circuit Signal vs Grounded Circuit Signal Open circuit signals can only be present in a circuit when there is a resistance of about 100 ohms or great- er. (Figure A) If a switch was to close in this circuit, (Figure B) the open circuit signals would cease to emit and the short/ Grounded Circuit signal would replace it. -
