The resistance should be between .45 - .55
Ω
at
20°C (68°F).
Otherwise, replace the ignition coil.
If resistance tests good, reconnect the ignition
coil connector and disconnect the AMP connector
number 3 on the MPEM.
Using a multimeter, recheck resistance value be-
tween terminals 21 and 22 for MAG side and ter-
minals 20 and 23 for PTO side.
If resistance value is correct, try a new MPEM. Re-
fer to MPEM REPLACEMENT procedures else-
where in this section.
If resistance value is incorrect, repair the wiring
harness/connectors between AMP connector and
the ignition coil.
Secondary Winding
Static Test
NOTE: An ignition coil with good resistance mea-
surement can still be faulty. Voltage leak can occur
at high voltage level which is not detectable with
an ohmmeter. A dynamic test is more effective.
Remove high tension lead from ignition coil.
Using a multimeter, check the resistance between
the terminals C and the coil post.
The resistance should be between 6800 and
10200
Ω
at 20°C (68°F).
If not within specification, replace the ignition coil.
Otherwise, perform the DYNAMIC TEST below.
Measure resistance of the high tension leads.
They must be as follows. Otherwise, replace the
lead.
NOTE: It is not necessary to remove the spark
plug cap.
IMPORTANT: Always replace leads with genuine
parts. Otherwise, fuel injection system operation
may be impaired.
Check continuity between ignition coil ground cir-
cuits and engine.
Dynamic Test
Use an ignition coil tester, available from after-market
tool/equipment suppliers.
1. With ignition coil removed from craft, hook high
tension leads from tester to ignition coil high
tension cable.
2. Connect 2 smaller tester leads to the primary
winding of ignition coil.
TYPICAL
1. Lead to high tension cable
2. Leads to primary winding
3. Turn power switch to 12 volts and you should
observe spark jumping at a predetermined gap
of 7 to 8 mm (.276 to .311 in).
If there is no spark, if it is weak or intermittent, the
coil is defective and should be replaced.

WARNING
Do NOT use coil tester on metal work bench.
Follow manufacturer instructions.

WARNING
Always reconnect spark plug cable to its original
spark splug. The cable coming out the edge of
the electrical box must be connected to the
MAG side spark plug. Otherwise, severe back-
fire may occur with possible damage to exhaust
system components. The white tape on the ig-
nition coil should match the white tape on the
high tension cable.
