Testing Electrical

Components

All tests of the engine electrical components should be
made using either the digital Fluke Model 73
Multimeter (p/n 0644-191) or the analog Multitester
(p/n 0644-033). Replace any component that does not
have a test value within specifications.

NOTE: Whenever using a digital-style tester,

“open (infinite resistance)” denotes an overload
and the meter reading will be OL since the meter is
not calibrated to register resistance values of that
magnitude.

NOTE: Whenever using an analog-style tester,

“open (infinite resistance)” denotes ohm count too
high to register, and the meter reading indicator will
remain stationary at the

∞

(infinity) position.

NOTE: Whenever testing switches, less than 1

ohm is desirable with the switch in the activated
position.

Troubleshooting

Ignition System

(EFI Models)

When troubleshooting the standard “normally open”
ignition system, use the following procedure.

1. Remove the spark plugs and visually check their

condition. Replace any fouled plug. Attach the
spark plugs to the high tension leads and ground
them on the cylinder heads.

Before checking for spark, place all the engine
switches in the deactivated position. In the event
the engine could be flooded, pull the starter rope
(slowly at first) several times to clear the engine
of excess fuel.

Never crank the engine over without grounding
the spark plugs. Damage to coils and/or CDI unit
may result.

NOTE: Make sure the ignition switch and the

emergency stop switch are in the ON position.

2. Crank the engine over and check for spark. If no

spark is present, check to make sure the throttle
cable is properly tensioned. Compress the throttle
control and while holding the throttle control in this
position, crank the engine over and check for spark.
If spark is now present, adjust the throttle cable
tension.

3. If no spark is present, disconnect the main wiring

harness from the engine. Crank the engine over. If
spark is present, the problem is either one or more
of the following:

a. Defective emergency stop switch

b. Defective safety switch in throttle-control

housing

c. Corroded or loose wire connection at the

throttle-control housing or main wiring harness

d. Defective ignition switch

e. Fouled spark plugs

f. Defective charge coil (high speed and low

speed)

g. Defective ignition timing sensor

h. Defective ECU or loose or corroded connection

in wiring harness

NOTE: To check these possible causes, proceed

to Testing Ignition System.

Testing Ignition

System

(EFI Models)

NOTE: There must be free-play between the

throttle lever and the control housing.

MAIN WIRING AND SAFETY SWITCHES

1. Check the wiring connections coming from the

ignition key and emergency stop switches. The
throttle control switch connector is located on the
front side of the steering post. If any of the
connections appear dirty or corroded, clean them
with fine sandpaper and compressed air; then
connect all wires and squeeze the connections with
a pliers for additional tightness.

2. Disconnect the main wiring harness connector

c o ming from t he engine stator as sembly.
Disconnecting this connector will bypass the main
wiring harness and all switches which will not
allow the engine to be shut off without first
installing an additional auxiliary ground wire.
