Tachometer failure

[docc]

You want the simple answer to the relay question?

 

From the front: starter, lights, side stand, computer, fuel system

 

Look here for more.

 

Of course, there's more to it.

 

The Sarter Relay and Headlamp Relay work in tandem to flow power to the lamp circuit through the lamp switch. When the Starter Relay is activated ( by pressing the start button with the clutch switch 'made') power is diverted to the starter solenoid and the lamps are defeated.

 

The "Sidestand Relay" is activated by the Neutral Switch. It flows power to the Run Switch which, in turn, activates the ECU Relay, Fuel Relay and electric petcock ( if your bike has one). In gear, power to the Run Switch flows through the Side Stand Switch itself bypassing the relay.

 

The ECU Relay is activated by current from the Run Switch . The power flow through the ECU Relay from Fuse 1 activates the Fuel Relay which flows power to the injectors, coils and fuel pump.
