Section 12
ELECTRICAL SYSTEM
Subsection 02
(IGNITION SYSTEM (CARBURETED ENGINES))
SMR2003-035_12_02A.FM
12-02-9
Access the
BOSCH SYSTEM
in the MPEM pro-
grammer, then select
ADJUSTMENT
in the sub-
menu.
Choose
IGNITION
in the
ADJUSTMENT
menu.
The screen will display the actual ignition timing
correction in degrees and it will also offer to adjust it.
Refer to the following chart to find the number cor-
responding to the timing correction needed.
Choose the
Fixed Timing
function, start the en-
gine and verify the timing again. Repeat the above
procedure if the timing is still incorrect.
Ignition timing is set at 12° BTDC at any RPM,
when the
Fixed Timing
function is active.
IGNITION SYSTEM TESTING
PROCEDURE
All Engines
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. Power supply cut-off relay.
7. Multi-Purpose Electronic Module (MPEM).
8. Magneto output (
717 engines
).
9. 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 111 (P/N 529 035 868)
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
NOTE:
The safety lanyard also controls the power
supply cut-off relay. Refer to INSTRUMENTS AC-
CESSORIES for its testing procedure.
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.
Rev Limiter Verification
To check engine rev limiter, connect an induction
tachometer (P/N 529 014 500), start engine and
check its maximum speed.
