GxT Ferret 63 DIAGNOSTIC ENGINE ANALYZER - Manual (Page 5)

This is a multiconductor cable which draws power from
the battery and senses the voltage. It should be the first
set of lead clips connected.
INDUCTIVE SPARK PICKUP
Cylinder synchronization and tachometer input are the
function of this lead. Features of this easy to use 8mm
wire spark current sensing pickup are dependable spark
pulse detection, ruggedness and plug-in replacement.
The unique design has an easy grip handle and a latch-
ing jaw mechanism for durability. The housing is made
of glass fiber reinforced plastic with high temperature
strength and solvent resistance.
INDUCTIVE AMPS PROBE
The Hall effect Amps Probe senses DC current in wires
without having to disturb connections and without intro-
ducing any voltage drop. Up to 20 mm (.75”) diameter
cables may be read. A distinctive arrow is marked on
both sides which indicates the direction of positive cur-
rent flow for a positive analyzer readout. Materials in
the probe are selected for enduring performance. If
damaged, a new probe may be plugged into the analyzer
without additional service.
EXTENSION HARNESS
A set of 4 identical cables are sheathed to form a har-
ness to extend the leads enough to reach from a carʼs
interior to the engine. They have color markers for lead
coordination. The long tailed end connects to the ana-
lyzer connector. Take care between door panels that it
does not get pinched enough to shear. Any of the leads
may be plugged directly into the analyzer without the
extension.
COIL PRIMARY / AUXILIARY LEAD CLIPS
Both clips have a prod tip and an insulation penetrating
pin cluster so they are adaptable to many connections.
The wires are neoprene insulated copper. The red clip
is used for auxiliary tests. The green clip lead, is always
connected to coil primary TACH.
TIMING-ADVANCE STROBE LIGHT
The Timing Light may be used when a spark signal and
power from the analyzer leads are present. Advance set-
tings are controlled and read directly from the calibrated
dial. The 2/4 stroke switch changes the dial calibration
by a factor of 2 for the ignition type.
To measure an engine's spark advance, clean the crank
wheel marks for good visibility and run the engine with
the appropriate test conditions. Turn the advance dial to
about the expected reading, press the light's trigger while
shining the light at the wheel marks, and then adjust the
knob so the marks appear aligned to TDC. The dial set-
ting is the spark advance angle in degrees of crank shaft
rotation.
The two trigger buttons control flash brightness. Opera-
tion of the analyzer is not affected by the Timing Light so
it may be unplugged any time.
