Oil Pressure Switch
Operation
The oil pressure switch is located under the oil filter
mounting boss on the crankcase (Figure 169). A pres-
sure-actuated diaphragm-type oil pressure switch is used.
When the oil pressure is low or when oil is not circulating
through a running engine, spring tension inside the switch,
holds the switch contacts closed. This completes the signal
light circuit and causes the low oil pressure indicator lamp
to light.
The oil pressure signal light should turn on when any of
the following occurs:
1. The ignition switch is turned on prior to starting the en-
gine.
2. The engine speed idle is below 1000 rpm.
3. The engine is operating with low oil pressure.
4. Oil is not circulating through the running engine.
NOTE
The oil pressure indicator light may not come
on when the ignition switch is turned off then
back on immediately. This is due to the oil
pressure retained in the oil filter housing. Test
the electrical part of the oil pressure switch in
the following steps. If the oil pressure switch,
indicator lamp and related wiring are in good
condition, inspect the lubrication system as
described in Chapter Two.
Testing/replacement
1. Disconnect the electrical connector from the switch
(Figure 169).
2. Turn the ignition switch on.
3. Ground the switch wire to the engine.
4. The low oil pressure indicator lamp on the instrument
panel should light.
5. If the indicator lamp does not light, check for a defective
indicator lamp, and inspect all wiring between the switch
and the indicator lamp.
6A. If the oil pressure warning light operates properly, at-
tach the electrical connector to the pressure switch. Make
sure the connection is tight and free of oil.
6B. If the warning light remains on when the engine is run-
ning, shut the engine off. Check the engine lubrication sys-
tem as described in Chapter Two.
7. To replace the switch, perform the following:
a. Unscrew the switch (Figure 169) from the engine.
b. Unless the new switch has pre-applied sealant, apply
pipe sealant to the switch threads prior to installation.
c. Install the switch and tighten it to 60-84 in.-lb. (7-9
N•m).
d. Test the new switch as described in Steps 1-4.
Neutral Indicator Switch
Testing/Replacement
The neutral indicator switch is located on the right side of
the crankcase in front of the drive sprocket (Figure 170).
The neutral indicator light on the instrument panel should
light when the ignition is turned on and the transmission is
in neutral.

cator switch and retest.
5B. If the neutral indicator lamp does not light, check for a
burned out indicator lamp, faulty wiring or a loose or cor-
roded connection. If necessary, replace the lamp as de-
scribed in this chapter.
6A. If the problem was solved in Steps 3-5, reconnect the
electrical connector to the neutral switch. Make sure the
connection is tight and free from oil.

Rear Brake Light Switch Testing/Replacement
A hydraulic, normally-open rear brake light switch is
used on all models. The rear brake light is located behind
the left side cover inline with the rear brake caliper brake
hose assembly (Figure 171). When the rear brake pedal is
applied, hydraulic pressure closes the switch contacts, pro-
viding a ground path so the rear brake lamp comes on. If the
rear brake lamp does not come on, perform the following:
1. Turn the ignition switch off.
2. Disconnect the electrical connectors from the switch.
3. Connect an ohmmeter between the switch terminals.
Check the following:
a. Apply the rear brake pedal. There should be continuity.
b. Release the rear brake pedal. There should be no con-
tinuity.
c. If the switch fails either of these tests, replace the
switch.
4. If necessary, replace the brake light switch as described
in the following steps.
5. Remove the rubber boot from the switch.
6. Place a drip pan under the switch, as some brake fluid
will drain out when the switch is removed.
7. Unscrew the switch from the T-fitting on the rear brake
line. Make sure to hold the T-fitting with a wrench when
performing Step 8.
8. Thread the new switch into the fitting and tighten it to
84-120 in.-lb.(9-14 N•m).
9. Reconnect the switch electrical connectors.
10. Bleed the rear brake as described in Chapter Sixteen.
11. Check the rear brake light with the ignition switch
turned on and the rear brake applied.

CIRCUIT BREAKERS
(1986-1997 MODELS)
All 1986-1997 models use circuit breakers to protect the
electrical system. Circuit breaker ratings for the various cir-
cuits are listed in Table 1.
Whenever a failure occurs in any part of the electrical
system, each circuit breaker is self-resetting and will auto-
matically return power to the circuit when the electrical
fault is corrected.
CAUTION
If an electrical fault on circuit-breaker
equipped models is not found and cor-
rected, the breakers will cycle on and off
continuously. This will cause the motorcy-
cle to run erratically and eventually dis-
charge the battery.

Most faults can be traced to a short circuit in the wiring.
This may be caused by worn-through insulation or by a
wire that has worked loose and shorted to ground. Occa-
sionally, the electrical overload that causes the circuit
breaker to trip may occur in a switch or motor. Use the wir-
ing diagrams at the end of the manual to determine which
circuits are protected by each circuit breaker.
All 1986-1993 models have four circuit breakers
mounted on the front side of the rear fender underneath the
seat (Figure 187). Refer to Figure 188 or Figure 189. Dis-
connect the negative battery cable prior to servicing the cir-
cuit breakers.
All 1994-1997 models have five circuit breakers. The ig-
nition, instruments, lights and accessories circuit breakers
are mounted in the circuit breaker block installed in the elec-
trical bracket mounted underneath the seat (Figure 190 or
Figure 191). The main circuit breaker is mounted in the elec-
trical bracket on the right side of the circuit breaker block
(Figure 184). Disconnect the negative battery cable as de-
scribed in this chapter prior to servicing the circuit breakers.
FUSES
(1998-2003 MODELS)
All 1998-2003 models use fuses (Figure 192) to protect elec-
trical circuits. Fuse ratings for each circuit are listed in Table 1.
Usually a blown fuse can be traced to a short circuit in the
wiring. This may be caused by worn-through insulation or
by a wire that has worked loose and shorted to ground. Oc-
casionally, the electrical overload that causes the fuse to
blow may occur in a switch or motor. Use the wiring dia-
grams at the end of this manual to determine which circuits
are protected by each fuse.
The ignition, instruments, lights and accessories circuit
fuses are mounted in the fuse block (3, Figure 193), which
is behind the starter relay (5) in the electrical bracket. Pull
up on the latch to release the fuse box. The main circuit
breaker is behind the cover on the electrical bracket.
Whenever a fuse blows, correct the electrical fault before
replacing the fuse.
