NEUTRAL INDICATOR SWITCH

7.23

GENERAL

See 

Figure 7-80.

 The neutral indicator switch (1) is threaded

into the transmission portion of the right crankcase half (2); it
is immediately forward of the main drive gear shaft (3). The
sprocket cover must be removed to test the switch. If switch
requires replacement, secondary drive belt and transmission
sprocket must also be removed; there is not enough clear-
ance to allow the removal of the switch without first removing
the transmission sprocket.

A pin on the shifter drum contacts the neutral indicator switch
plunger, completing the neutral indicator circuit. The switch is
not repairable. Replace the switch if it malfunctions.

For diagnostic information, see Section 

7.28 INDICATORS
