Details
VDC is the voltage at the tester
AMP is the circuit amperage the tester is reading
AUX, BLUE, PIN 7 indicates 7-Way PIN number
and circuits are currently being tested (see Pin
Numbers and Circuits below)
Electrical circuits will display “GOOD” if greater
than 10mA and less than 15Amps and no other
faults are found
“SHORT” – Shorted circuit fault
Fault with multiple circuits involved when a single
circuit is under test. The tester has identified
electrical activity on more than one circuit.
The panel circuit indicator lights illuminate for all
shorted circuits, and the “
SHORT
” fault alarm
sounds. The digital display indicates the circuit
under test, current draw, voltage and a
SHORTED
circuit fault. Amperage shows the total circuit load
on the digital display.
This screen is identifying a short to the right turn
signal. The shorted circuits on the left turn signal
will be illuminated on the tester panel along with the
right turn signal.
“CHASSIS SHORT” – Ground Fault
Fault with circuit supply wire in contact with the
chassis or ground circuit.
The panel circuit indicator light is on and the
“CHASSIS” fault alarm sounds. Current to the
trailer is restricted, and the digital display shows
0.00 amperage.
This screen is identifying that the marker circuit wire
is shorted to the chassis. The tester’s software
protects the vehicle harness by pulsing the power
every 5 to 8 seconds.
