CAUTION:
If the ignition timing is adjusted too
advanced, this will cause serious damage to
the engine.
Refer to the timing correction charts, used per
MPEM Programmer
, to find the number corre-
sponding to the timing correction needed.
IGNITION SYSTEM TESTING
PROCEDURE
When dealing with ignition problems, the follow-
ing items should be verified in this order:
1. Spark occurrence/spark plug condition.
2. Battery condition.
3. Electrical connections.
4. Engine start/stop switch.
5. Safety lanyard switch.
6. Timer.
7. Multi-Purpose Electronic Module (MPEM).
8. Ignition coil output.
CAUTION:
Whenever replacing a component
in ignition system, check ignition timing.
NOTE:
To perform verification, a good quality mul-
timeter such as Fluke 73 (P/N 529 022 000) should
be used.
Engine Start/Stop Switch Verification
Disconnect the YELLOW/RED wire of the start/
stop switch. Using an ohmmeter, connect test
probes to YELLOW/RED wire and to ground.
Measure resistance, it must be an open circuit
(switch is normally open). Depress and hold switch,
the ohmmeter should read close to 0 ohm.
Safety Lanyard Switch Verification
If 2 short beeps are not heard when installing the
safety lanyard, refer to DIGITALLY ENCODED SE-
CURITY SYSTEM.
The following continuity tests can also be per-
formed using an ohmmeter:
Disconnect switch wires.
Safety Lanyard Removed
Connect test probes to switch BLACK and BLACK/
YELLOW wires. Measure resistance, there should
be no continuity (open circuit).
Connect one test probe to the WHITE/GRAY wire
and the other test probe to the switch terminal.
Measure resistance, it must be close to 0 ohm.
Connect one test probe to the BLACK wire and the
other test probe to the switch ring. Measure resis-
tance, it must be close to 0 ohm.
Safety Lanyard on Switch
Connect test probes to switch BLACK and BLACK/
YELLOW wires. Measure resistance, it must be
close to 0 ohm.
Timer Verification
The timer is integrated into the MPEM.
Always confirm first that the fuses are in good
condition.
To confirm operation of timer, remove safety lan-
yard from switch. After a 5 seconds delay, depress
start/stop button once. The timer should stay on
for about 33 seconds (for example, gauge(s) will
be activated) and then turn off.
Rev Limiter Verification
To check engine rev limiter, connect an induction
tachometer (P/N 295 000 100), start engine and
check its maximum speed.
Multi-Purpose Electronic Module
(MPEM) Verification
It is not possible to accurately check the MPEM
condition without specialized tools. Therefore, re-
place MPEM with a good known unit to conduct
testing.
NOTE:
Before replacing the MPEM, make sure all
connectors are properly secured and there is no
water in connectors. Check also the signal and
power contacts in the AMP plug connectors. See
WIRING DIAGRAMS.
