ELECTRICS 2.33 Procedure 4. Drive the machine for approximately 15 minutes so that axle reaches normal operating temperature. 5. Stop the machine in the following condition: - On straight and level ground - With all wheels straight ahead - Ensure parking brake released - With the boom pivot point and the carriage pivot point at the same height - With the boom fully retracted - Ensure forks and front attachments removed. 6. Disconnect load sensor electrical connector (A) on rear axle. 7. Using a multimeter set to mV and test probes Part No. 365 747.0, connect test probes to pins 3 and 4 of connector (A2). Green cable (pin 3) = + signal voltage Yellow cable (pin 4) = - signal voltage 8.
Switch on the ignition and the main hydraulic switch. 9. Carry out the following tests: - Test the reading when the machine is not loaded - Test the reading when the machine is at maximum permissible weight (test weight) - The reading should be approximately 1.5 - 2.0 mV less at maximum permissible weight than when not loaded. NOTE: The reading can indicate a negative value.
