CHECKING THE SWITCHES ELEC EAS00731 ELECTRICAL CHECKING THE SWITCHES Check each switch for damage or wear, proper connections, and also for continuity between the terminals. Refer to “CHECKING SWITCH CONTINUITY”. Damage/wear Repair or replace. Improperly connected Properly connect. Incorrect continuity reading Replace the switch. -3- ELECTRIC STARTING SYSTEM ELEC EAS00755 ELECTRIC STARTING SYSTEM CIRCUIT DIAGRAM -4- ELECTRIC STARTING SYSTEM ELEC 4 Main fuse 5 Battery 7 Starter relay 8 Starter motor 9 Main switch 12 Starting circuit cut-off relay 13 Sidestand switch 14 Neutral switch 49 Clutch switch 59 Engine stop switch 60 Start switch 61 Ignition fuse -5- ELECTRIC STARTING SYSTEM ELEC EAS00756 STARTING CIRCUIT CUT-OFF SYSTEM OPERATION If the engine stop switch is set to “” and the main switch is set to “ON” (both switches are closed), the starter motor can only operate if at least one of the following conditions is met: The transmission is in neutral (the neutral switch is closed). The clutch lever is pulled to the handlebar (the clutch switch is closed) and the side- stand is up (the sidestand switch is closed). The starting circuit cut-off relay prevents the starter motor from operating when neither of these conditions has been met. In this instance, the starting circuit cut-off relay is open so current cannot reach the starter motor. When at least one of the above conditions has been met the starting circuit cut-off relay is closed and the engine can be started by pressing the starter switch. WHEN THE TRANSMISSION IS IN NEUTRAL WHEN THE SIDESTAND IS UP AND THE CLUTCH LEVER IS PULLED TO THE HANDLEBAR 4. Starting circuit cut-off relay Disconnect the starting circuit cut-off relay from the wire harness. Connect the pocket tester (Ω 1) and battery (12 V) to the starting circuit cut-off relay terminals as shown. YES NO Replace the starting circuit cut-off relay.

Step 1) Wire Connection: Using 18-gauge automotive wire, connect the audio alert relay as shown in the Wiring Diagram – Figure 1. • Connect the supplied wire from #3 terminal on the audio alert relay to the oil pressure switch post. Note: The supplied wire is not reversible. The eyelet end must hook to the oil pressure switch. • Connect a wire from #2 terminal on the audio alert relay to the ignition switch post that receives power when the ignition switch is first turned on. • Connect a wire from #1 terminal on relay to the positive side of existing horn, or alternate sound device. • Note: The audio alert relay uses the oil pressure switch as its ground. On most motorcycles, this audio alert relay can be installed easily under the dash. Figure 1- Wiring Diagram Cot a Oil Pressure Switch Ignition Switch Audio Alert Relay 2 1 3 load Horn + + – Caution: Make sure all connections are insulated away from potential grounds. Do not disconnect any existing wire. Step 2) Testing : Turn ignition switch on and ensure oil pressure light is on. Leave ignition switch on. Wait 30 sec (T1) and ensure the audio alarm sounds for ½ second (T2). If the electrical test is successful, proceed to Step 3. If not, you may have to use a pezio alert in place of the horn. (Which is available at most Radio Shack stores.) If audio alert still doesn’t work, consult the wiring diagram and recheck all wiring connections. Verify timer set points have not been altered. If problems persist, contact us at (518) 884-9591. Step 3) Mount relay switch: Use standard zip ties (not provided) or similar means to mount the relay to dash mount post or dash base. Note: The timer relay can be mounted almost anywhere on the bike that will not be exposed to direct rain or weather
