SAFETY PRECAUTIONS

WARNING : To prevent powerful electric

shocks while cranking engine, neither

touch any electronic ignition components (ig-

nition coil, high tension wires, etc.) nor tester

lead clips. Also make sure that tester leads do

not touch any metallic object. Ventilate bilge at

least two minutes prior to performing any test.

IGNITION SYSTEM TESTING

PROCEDURE

When dealing with ignition problems, the follow-

ing items should be verified in this order.

1. Spark occurence / spark plug condition.

2. Battery condition.

3. Electrical connections.

4. Engine start / stop switch.

5. Safety lanyard switch.

6. Delay timer .

7. Multi-purpose electronic module (MPEM).

8. Magneto output.

9. Ignition coil output.

CAUTION : Whenever replacing a compo-

nent in ignition system, check ignition

timing.

NOTE : To perform verification, a good qual-

ity multimeter such as Fluke 73 (P / N 529

022 000) can be used.

Engine Start / Stop Switch Verification

Disconnect the YELLOW / RED wire in the electri-

cal box. Using an ohmmeter, connect test probes

to YELLOW / RED wire and to ground near sole-

noid.

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

Disconnect the BLACK and BLACK / YELLOW

wires in the electrical box. Using an ohmmeter,

connect test probes to switch wires.

Measure resistance, it must be close to 0 ohm

when cap is over switch and an open circuit when

removed.

Delay 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 and depress start / stop button

once. The timer should stay on for about 33 sec-

onds (for example, fuel gauge will be activated)

and then turn off.

587 and 717 Engines

Multi-Purpose Electronic Module

(MPEM) Verification

The multi-purpose electronic module testing must

be done with all wires disconnected from circuit.

Otherwise testing equipment (ohmmeter) could

be damaged.

CAUTION : When disconnecting wires,

BLACK /RED wire must never touch sole-

noid positive terminal. When replacing a

MPEM, make sure to replace it with the right

model.

Refer to the following chart for MPEM testing. Al-

ways respect polarity in chart.
