GxT Ferret 63 DIAGNOSTIC ENGINE ANALYZER - Manual (Page 23)

TEST VARIATIONS
Alternately, a remote starter switch may be used, but
power must be on the ignition or cranking RPM will not
be measured.
The engine may start if ignition compatibility has not been
established. Allow it to run for a minute until the situation
is resolved.
If the green Coil Primary Clip is not getting a signal, or if
the ignition does not have a distributor, and has not been
disabled, the engine may start and the test will be inter-
rupted with the display:
If the ignition cannot be automatically suppressed be-
cause it has more than one coil, or is not the usual
inductive discharge type, then the user must manually
disable the engine.
Use the recommended method to disable the engine for
compression cranking tests from the vehicle service man-
ual. This will usually be by unplugging the power wire
or fuse to the fuel injectors or ignition coils. Additionally,
unless there is a simulated Coil Primary TACH signal,
RPM cannot be read. When ready, press START.
If the battery voltage falls below 9.6 volts during the test,
it is too low to continue and one of the following mes-
sages will be shown:
The test will stop and the operator should check the bat-
tery-starting system accordingly.
