Direction to the Short
The Short/Grounded Circuit signal is polar-
ized. This gives the receiver the information
it needs to show you the direction to the short
or the direction to ground. When you place the
receiver’s
“Open & Short Pick-Up” parallel to the wire
of the Grounded Circuit signal, “Direction to
Short/Ground” indicator will point you in the
direction to ground. If you were to flip the
receiver in the opposite direction it will detect
the polarity change, the “Direction to Short/
Ground” indicator will flip, and it will still point
you in the direction to ground. Keep in mind
that the receiver’s “Open & Short Pick-Up”
must be held parallel to the circuit for the “Di-
rection to Short/Ground” to indicate.
The ECT3000 works equally well with either
positive chassis ground or negative chassis
ground. The only thing you need to keep
in mind is, when tracing short circuits the
receiver always points you towards the minus of
the battery so if you have a short between your wiring and the chas-
sis is a positive ground system, you just need to trace in the opposite
direction the LED is pointing!
