GxT Ferret 54 ENGINE DIAGNOSTIC CENTER - Manual (Page 40)

HARD START — Distributor
Press IGNITION, SELECT Hard Start and press NEXT. Use this test to find the problem area
on a no-start engine. If a Distributor ignition was selected during Engine Setup , this screen
will appear:
256 RPM 80û Battery 10.95 Volt
142 Amp(ZeroÛ) Aux~NEG 10.95 Volt
38 IgEgy Aux~POS 00.00 Volt
2.4 Dwell mS ~ AC P-P 00.0 Volt
The ignition signal for this test comes from the Coil Primary Clip connected to the Coil (-),
TACH terminal of the coil.
The Amps reading shows starter draw, measured by the Inductive Amp Probe. The probe should
be zeroed before testing. To zero, press NEXT and follow the on-screen instructions. Ignition
Energy shows the coil's charge level. Dwell shows coil charging time. Auxiliary Volts can be
measured, using the Auxiliary Meter Lead, to confirm that voltage is present at the ignition or
to detect voltage drops in cables and connections. Voltage at the lead, referenced to both the
positive and negative battery power clips, is shown. Volts AC P-P (peak-to-peak) can be used
to check the output of pulsing type sensors. RPM and Battery Voltage are used to measure
the performance of the cranking system. Special diagnostics pick out problems with the spark
plugs, wires, cap and rotor.
HARD START — DIS or Distributor with no Coil (-) Terminal
If a DIS or a Distributor with No Coil (-) ignition was selected, the Hard Start screen will look
like this:
256RPM 80û Battery 10.95 Volt
142 Amp(ZeroÛ) Aux~NEG 10.95 Volt
9.2 PkAmp Aux~POS 00.00 Volt
3.1 Bld. mS AC P-P 00.0 Volt
This screen is similar to the one for Distributor ignitions, but Peak Amps and Build Time are
measured instead of Ignition Energy and Dwell.
