EMERGENCY SHUT-OFF SWITCH

The emergency shutoff switch is a mechanical switch and mounted behind the headlight. This switch will shut off the ignition system if for any reason the motorcycle reaches a lean angle of 60 degrees or more from vertical.

Removal

1.    Remove the required fairing.

2.    Disconnect the lead wires from the wire harness and pull out the switch assembly from its rubber mounting harness.

1. Emergency shut-off switch  2. Rubber mounting  3.  Fuel pump relay

Inspection

1.    Connect the pocket tester leads as shown.

2.    The tester (with ohms x 100 scale) needle should show infinity {) when the switch is positioned vertically as shown. Replace the switch if it shows 0Ω

1. Weight contact

3. The tester (with ohms x 100 scale) needle should swing to 0Ω when the switch is leaned about 60 degrees or more to either left or right from the vertical position.

Replace the switch if it shows infinite resistance ().

Installation

CAUTION: Install the switch with the arrow pointing up. or the switch will not operate correctly.

SIDESTAND SWITCH

1.     Remove the seat.

2.     Remove the side panels as one piece.

3.    Disconnect the connector from the wiring harness.

4.    Connect the pocket tester leads as shown, and set the tester selector to ohm x 1. When the sidestand is up, the tester should read zero ohms. When the side-stand is down, the tester should read infinity.

SIDESTAND RELAY

1.    Remove the seat and the side panels.

2.    Disconnect the connector and remove the sidestand relay.

3, Check the resistance of the relay coil windings with the pocket tester. If the resistance is not within specification, replace the relay.

4. Check the relay contact breaker points with the pocket tester and a 12 volt battery. Connect the leads as shown in the illustration. If the resistance readings do not equal those shown in the illustration, replace the relay.

1. When the battery is connected. 2. When the battery is disconnected.
3. 12 volt battery

STARTING CIRCUIT CUT-OFF RELAY

1.    Remove the required fairing.

2.    Disconnect the connector.

3.    Remove the starting circuit cut-off relay.

1. Starter circuit cut-off relay

4. Check the resistance of the relay coil windings with the pocket tester. If the resistance is not within specification, replace the relay.

5. Check the relay function with a 12 volt battery and the pocket tester. Connect the leads as shown in the illustration. If the resistance readings do not equal those shown in the illustration, replace the relay.

CAUTION: Wrong connection of the battery leads may cause damage to the relay diode.

6. Check the diode in the starting-circuit cut-off relay with the pocket tester as shown in the illustration. Replace the relay if the diode is damaged.

1. When the balterv is conrwcted. 2. When the battery is disconnected. 
3. 12 volt battery

NOTE: Only the Yamaha Pocket Tester will give a 9.5Ω reading when testing continuity. The particular characteristics of other testers will vary the continuity test readings.

FUEL PUMP RELAY

1.  Remove the required fairing.

2.    Disconnect the connector.

3.    Remove the fuel pump relay.

1. Fuel pump relay

4. Check the resistance of the relay coil windings with the pocket tester. If the resistance is not within specification, replace the relay.

5. Check the relay function with a 12 volt battery and the pocket tester. Connect the leads as shown in the illustration. If the resistance readings do not equal those shown in the illustration, replace the relay.

1. When the battery is connected.    2 When the battery is disconnected.   
3.  12 volt battery

Emergency engine stop relay inspection

1.    Remove the seat.

2.     Remove the side panels as one piece.

3.    Remove the lower panel securing bolts (2X2).

1. Side panel   2. Lower panel

4.    Remove the fuel tank.

5.    Disconnect the connecter and remove the emergency engine stop relay.
