Position switch as it is located in vehicle. Resistance
should be close to 0
Ω
.
Rotate switch as it would do in vehicle. Switch
should remain closed up to approximately 120°
(from the vertical axis) in either direction. Other-
wise, replace switch.
NOTE:
Since this is a mercury switch, dispose it
properly according to the environmental regula-
tions in your area.
Farther than 120° and when switch is upside
down, switch should be open and resistance will
be infinite.
IGNITION COILS
1. Ignition coil
NOTE:
The MPEM energizes the primary side of
each ignition coil individually. It can detect open
and short circuit in the primary winding but it does
not check the secondary winding.
Using the vehicle communication kit (VCK) with
the B.U.D.S. software, energize the ignition coil
from the
Activation
section.
You should hear the spark occurring. In doubt, use an
inductive spark tester or a sealed tester – available
from after-market tool/equipment suppliers – to pre-
vent spark occurring in the bilge. Otherwise, perform
the following checks.
An ignition coil with good resistance measure-
ment can still be faulty. Voltage leak can occur at
high voltage level which is not detectable with an
ohmmeter. Replacing the ignition coil may be nec-
essary as a test.
Voltage Test
Disconnect the connector from the ignition coil
and check the voltage supplied by the MPEM.
Install safety lanyard on the DESS post.
Check voltage between terminal 2 of ignition coil
connector on the wiring harness and battery
ground.
The voltage should be 12 V.
If 12 V is NOT read, check continuity of appropri-
ate circuit 2-16 (cylinder 1), 2-17 (cylinder 2) or 2-18
(cylinder 3). If it tests good, try a new MPEM.

WARNING
Never make a spark test with spark plug re-
moved. Flammable vapors may be present in
the bilge and ignited which could cause an ex-
plosion.
WARNING
When disconnecting coil from spark plug, al-
ways disconnect coil from main harness first.
Never check for engine ignition spark from an
open coil and/or spark plug in the engine
compartment as spark may cause fuel vapor
to ignite.
