If the warning buzzer does not make a noise under these conditions, use the following procedure to find the cause of the problem: 1. Make sure that the engine is stopped. Find the connection point at which the jumper wire for the switch for engine oil pressure is connected to the main wiring harness. Disconnect the jumper wire from the main wiring harness. 2. Connect one ohmmeter lead to the end of the jumper wire. Connect the other ohmmeter lead to a good ground point on the engine. The ground point must be free of paint and dirt. The ohmmeter needle must move toward zero. If the ohmmeter needle does not move toward zero, the problem is in the jumper wire or the switch for engine oil pressure. Repair as necessary. If the ohmmeter needle moves toward zero, continue with step 3. 3. Remove the seat and heat shield assembly from the machine. Turn the key switch to the RUN position but do not start the engine. Use a voltmeter to check for system voltage at the key switch terminal to which the warning buzzer is connected. If the voltage indication is not correct at the terminal, install a new key switch. If the voltage indication is correct, continue with step 4. 4. See Figure 5. Find the connection point at the top of the warning buzzer. The jumper wire for the warning buzzer is connected to the warning buzzer at this connection point. Make sure that the key switch is in the RUN position. Use a voltmeter to check for system voltage at the connection point. If the voltage indication is not correct, install a new warning buzzer. If the voltage indication is correct, the problem is a break in continuity in the jumper wire or the main wiring harness. Repair as necessary.
