Electrical System104Service Manual – CS7000All models have a large connector to disconnect power from the machine. A circuit breaker panel located onthe left side of the operator foot well area provides circuit protection for multiple circuits.The electrical system makes use of hall effect current sensors to provide amp draw information to the mainmachine controller for some circuits.Wiring HarnessesWires are color coded and have connector information printed near each end of the wire. In the photo below,the left end of the wire goes to connector X274 pin A and the right side of the wire goes to connector J3 pin 9.The main harness is the same for all models. Connectors which are not used for certain models or featureshave plugs covering them or may be “jumped” together as is the case for the battery interlock switch onengine models.There are splices in the harness that are shrink wrapped. There are also two “splice saver” connectors whichlook like capped off connectors, but actually connect many wires together through a “comb” that is insertedinto the connector.The CAN Bus wire pairs are twisted to prevent electrical interference from corrupting the messages. If anyrepairs are performed on the CAN Bus wires, the wire pairs must be twisted approximately once per inch.Current Sensor
