![]() ![]() Resistance that is greater than 5 ohms can cause incorrect diagnosing of problems. Signal circuits ("sensors, switches, solenoids etc.") require less than 5 ohms of resistance for normal operation. ![]() The power circuits of the control require less than 2 ohms of resistance between the ground contacts of the connector and frame ground. At component connectors, always check the ground circuit. Perform continuity checks at the connectors in order to locate the harness failures. When the troubleshooting procedure instructs the service personnel to REPAIR THE HARNESS, always use the Electrical System Schematic that is located in the machine Service Manual to trace the circuit. Refer to the Electrical System Schematic that is located in the machine Service Manual for a complete representation of the machine that is being diagnosed. Troubleshooting the Vital Information Management System requires additional information from the machine Service Manual, the Electrical System Schematic, and the Operation and Maintenance Manual.Īs a guide, a "VIMS schematic" is provided in the Testing and Adjusting section of this manual.
