For a complete representation of the machine that is being diagnosed, refer to the Electrical System Schematic in the Service Manual of the machine. When the troubleshooting procedure instructs you to “REPAIR THE HARNESS OR REPLACE THE HARNESS”, use the Electrical System Schematic in the Service Manual of the machine to trace the circuit. Perform resistance checks at the harness connectors in order to locate harness failures. Always check the ground circuit at the machine harness connector for the components. Less than five ohms of resistance is required between the ground contacts of the connector and the frame ground. Excessive ground resistance that is greater than five ohms can cause an incorrect diagnosis of the system.During troubleshooting, inspect all harness connections before any component is replaced. If these connections are not clean and tight, permanent electrical problems or intermittent electrical problems can result. Check that the wires are pushed into the connectors completely. Make sure that the connections are tight before other tests are made. Failure of an electrical component can cause the failure of other components. Always attempt to correct the cause of an electrical system failure before you replace a component. If wire insulation is punctured during troubleshooting, repair the damage. Seal the damaged wires with 8T-0065 RTV Silicone Sealant. Cover the sealant with two layers of 1P-0810 Electrical Tape.ECM Pull Up Voltage
