CHECKING THE FUSES

The following procedure applies to all of the fus-
es.
ECA20520
NOTICE
To avoid a short circuit, always turn the main
switch to "OFF" when checking or replacing
a fuse.
1. Remove:
• Rider seat and passenger seat
Refer to "GENERAL CHASSIS" in base ser-
vice manual B97-F8197-E0 on page 4-1.
2. Check:
• Fuse
a. Connect the multimeter to the fuse and
check the continuity.
TIP
Set the multimeter selector to "  1".
Multimeter

(90890-03189)
b. If the multimeter indicates "", replace the
fuse.
3. Replace:
• Blown fuse
a. Set the main switch to "OFF".
b. Install a new fuse of the correct amperage
rating.
c. Set on the switches to verify if the electri-
cal circuit is operational.
d. If the fuse immediately blows again, check
the electrical circuit.

WARNING
Never use a fuse with an amperage rating
other than that specified. Improvising or us-
ing a fuse with the wrong amperage rating
may cause extensive damage to the electri-
cal system, cause the lighting and ignition
systems to malfunction and could possibly
cause a fire.
4. Install:
• Rider seat and passenger seat
Refer to "GENERAL CHASSIS" in base ser-
vice manual B97-F8197-E0 on page 4-1.

CHECKING THE AIR INDUCTION SYSTEM
SOLENOID
1. 1.Check:
• Air induction system solenoid resistance
Out of specification  Replece.
Solenoid resistance
20-24  at 20° C
a. Disconnect the air induction system sole-
noid coupler from the air induction system
solenoid.
b. Connect the multimeter (  1) to the air
induction system solenoid terminal as
shown.
Multimeter

• Positive tester probe 
Air induction system solenoid terminal "1"
• Negative tester probe 
