The electrical system chapter contains wiring diagrams, electrical panel information and covers other
components that are not covered in other chapters. For instance, the Solution Pump is covered in the
Solution System Chapter.
Functional Description
Overview
The CS7010 is an electrically driven system, but with various prime-power congurations. All congurations
utilize a 36-volt battery system, but the hybrid models incorporate engine-alternator power generation to
constantly charge the batteries.
When the engine is running the alternator provides the electrical power to operate the machine electrical
loads as well as recharge the battery pack. If the machine’s instantaneous power demand is higher than the
alternator can provide, the battery pack supplies the extra boost that is needed. If the engine is not running
the machine can work for a limited time on just the battery pack
Another unique aspect of the Hybrid models is that they also have a separate 12 volt battery, which is
primarily for starting the machine, but also powers engine related functions. The engine contains a separate
alternator for charging this system.
All models have a large connector to disconnect battery power from the machine, however, note that this
does not disconnect the batteries from the engine generator. A circuit breaker panel located on the left side
of the operator foot well area provides circuit protection for multiple circuits.
Wiring Harnesses
Wires 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 features have plugs covering them
or may be “jumped” together as is the case
for the battery interlock switch on engine
models.
The CAN Bus wire pairs are twisted to
prevent electrical interference from corrupting the messages. If any repairs are performed on the CAN Bus
wires, the wire pairs must be twisted approximately once per inch.
