9 24 Electrical system 10 If the switch is good check the wiring and connectors between the various components in the starter safety circuit using a continuity tester see the wiring diagrams at the end of this book Also check for voltage at the green white wire terminal on the loom side of the connector with the ignition ON there should be battery voltage Repair or renew the wiring as required Replacement 23 13 Sidestand switch mounting bolt arrowed green yellow and green wire terminals on the switch side of the connector with the sidestand up there should be continuity zero resistance between the terminals and with the stand down there should be no continuity infinite resistance Now connect the meter between the pink and green wire terminals on the switch side of the connector with the sidestand up there should be no continuity infinite resistance between the terminals and with the stand down there should be continuity zero resistance 7 On XL600V R to X 1994 to 1999 models and XRV750 P models onward 1993 on connect the meter between the green white and green wire terminals on the switch side of the connector with the sidestand up there should be continuity zero resistance between the terminals and with the stand down there should be no continuity infinite resistance Now connect the meter between the yellow blauk and green wire terminals on the switch side of the connector with the sidestand up there should be no continuity infinite resistance between the terminals and with the stand down there should be continuity zero resistance 8 On XL650V models connect the meter between the green white and green wire terminals on the switch side of the connector with the sidestand up there should be continuity zero resistance between the terminals and with the stand down there should be no continuity infinite resistance 9 If the switch does not perform as expected It is faulty and must be replaced with a new one 11 The sidestand switch is mounted either on the frame next to the sidestand or on the back of the sidestand depending on whether it is a plunger type switch or a rotary type Trace the wiring back from the switch and disconnect at the wiring connector remove the seat and or left hand side panel to access it see Chapter 8 Work back along the switch wiring freeing it from any clips and ties noting its correct routing 12 On XL600V K to P 1989 to 1993 models and XRV750 L to N 1990 to 1992 models unscrew the switch cover bolts and remove the cover then unscrew the remaining switch bolt and remove the switch noting how it fits Fit the new switch onto the bracket making sure the plunger locates correctly against the sidestand Secure the switch and Its cover with the bolts and tighten them securely 13 On XL600V R to X 1994 to 1999 models XL650V models and XRV750 P models onwards 1993 on unscrew the switch bolt and remove the switch from the stand noting how it fits see illustration Fit the new switch onto the sidestand making sure the pin locates in the hole in the sidestand and the lug on the stand bracket locates into the cutout in the switch body Secure the switch with its bolt and tighten it to securely 14 Make sure the wiring is correctly routed up to the connector and retained by any clips and ties 15 Reconnect the wiring connector and check the operation of the switch 16 Install the seat and or left hand side panel as required see Chapter 8 24 Clutch switch check and replacement components in the starter circuit as described in the relevant sections of this Chapter II all components are good check the wiring between the various components see the wiring diagrams at the end of this book Replacement 4 The clutch switch is mounted on the clutch lever bracket 5 Disconnect the wiring connectors from the switch see illustration 24 2 Remove the single screw securing the switch to the bracket and remove the switch noting how It fits see illustration 6 Installation is the reverse of removal Install the switch with the small catch at the bottom and press it in until the catch is felt to locate 25 Diode s check and replacement 1 The diode s is are part of the starter safety interlock system see Section I A diode isa small block that allows current flow in one direction only and plugs into a connector either in the I usebox or in the wiring loom depending on the model application Refer to the relevant Wiring Diagrams at the end of the Chapter for details 2 There is usually a diode in the clutch switch circuit housed in the fusebox one for the sidestand switch circuit that plugs Into the loom and can usually be identified by the tact that it has black insulating tape wrapped round it and is usually located under the seal or behind one of the side panels see illustrations opposite and one for the neutral switch circuit that is integral with the ignition control unit Twin terminal diode blocks contain one diode and triple terminal diode blocks contain two diodes Using the Wiring Diagrams identify which is are the input terminal s and which is the output terminal the input s have the line which leads to the flat side of the triangle on the symbol and the output comes from the line across the point of the triangle 3 To test a twin terminal diode connect the positive probe of an ohmmeter or continuity tester to the input terminal on the Check 24 2 Clutch switch wiring connectors arrowed 1 The clutch switch is mounted in the clutch lever bracket The switch is part of the starter safety interlock system see Section 1 The switch isn t adjustable 2 To check the switch disconnect the wiring connectors from it see illustration Connect the probes of an ohmmeter or a continuity tester to the two switch terminals With the clutch lever pulled in there should be continuity zero resistance With the clutch lever out there should be no continuity Infinite resistance 3 If the switch is good check the other 24 5 Clutch switch screw anowed
