Ignition Test 3 - Clutch Switch Function
CONDITION: Sidestand down, key ON, transmission in gear and clutch disengaged
TESTING/REPLACEMENT
Side Stand Switch
See Figure 7-33. The side stand switch is a simple spring
loaded plunger. The switch completes a path to ground for
the ignition relay when the side stand is in the retracted posi-
tion. Test the switch as follows:
1. Unplug the 2-place side stand switch connector [60].
2. Test the switch using an ohmmeter.
a. With side stand down (switch open), the switch
should show ∞ ohms (infinite ohms).
b. With side stand up (switch closed), the switch
should show 0 ohms or little resistance.
3. Replace the assembly with a new switch if necessary.
a. Remove side stand switch from Sidestand by
removing two bolts and nuts.
b. Apply LOCTITE THREADLOCKER 243 (Blue) to
threads of two bolts.
c. Install new sidestand switch with two bolts and nuts.
Tighten bolts to 30-36 in-lbs (3-4 Nm).
Clutch Switch
See Figure 7-34. The clutch switch attaches to the clutch con-
trol lever bracket. The switch completes a path to ground for
the ignition relay and the starter relay when the clutch is dis-
engaged. Test the switch as follows:
1. Unplug the 2-place clutch switch connector [95].

System OK.
YES
Remove Seat. Remove fuse block from frame tab. Turn
fuse block upside down to access terminals. Measure
voltage between Diode 2 (-) (TN/Y) and Ignition Fuse (+)
(GY).
Is Voltage equal to Battery Voltage minus 0.7 +/- 0.1V?
Check for continuity between Socket B
(TN/Y) [134B] and Diode 2.
Is Continuity present?
