DYNAMIC TEST
1. Connect spark plug cables to grounding device.
2. Disconnect magneto wiring harness connector.
3. Install the 4-pin magneto harness adapter (P/N
295 000 131).
4. Connect positive test probe of the multimeter
to the RED/BLACK wire of the 4-pin magneto
harness adapter.
5. Connect negative test probe of the multimeter
to BLACK wire of the 4-pin magneto harness
adapter.
6. Set multimeter to Vac scale.
7. Crank engine and note result. The obtained val-
ue should be between 18 and 25 Vac.
8. If the generating coil is out of specification, re-
place it.
NOTE: If the generating coil tests good, discon-
nect the primary wires of the ignition coil. Crank
engine and check voltage at primary wires. It
should be at least 20 Vdc. If there is insufficient or
no voltage, either the MPEM or wiring harness is
defective.
Trigger Coil Verification
787 and 947 Engines
STATIC TEST: CONTINUITY
1. Disconnect magneto wiring harness connector.
2. Install the 6-pin magneto harness adapter (P/N
295 000 136).
3. Connect one of the multimeter probes to the
WHITE wire of the 6-pin magneto harness
adapter.
4. Connect the other multimeter probe to the BLACK/
YELLOW wire of the 6-pin magneto harness
adapter.
5. Measure resistance; it should be between 190-
300 ohms.
1. Multimeter
2. Six-pin magneto harness adapter
3. WHITE wire
4. BLACK/YELLOW wire
DYNAMIC TEST
1. Disconnect magneto wiring harness connector.
2. Install the 6-pin magneto harness adapter (P/N
295 000 136).
3. Connect one of the multimeter probes to the
WHITE wire of the 6-pin magneto harness
adapter.
4. Connect the other multimeter probe to the BLACK/
YELLOW wire of the 6-pin magneto harness
adapter.
5. Crank engine and note result. The obtained val-
ue should be between 0.2 and 0.5 Vac.
6. If the trigger coil is out of specification, replace
it.
Ignition Coil Verification
All Engines
Before conducting any testing on the ignition coil,
make sure there is at least 20 Vdc at the primary
wires. If there is insufficient voltage, the ignition
problem is occurring before the ignition coil.
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.
