APPENDIX E
M876 ELECTRICAL SYSTEMS FUNCTIONAL DIAGRAMS
The M876 electrical systems functional diagrams shown in this appendix are provided to perform troubleshooting and
maintenance procedures.
Each functional diagram shows related components and harnesses and basic wire routing. Due to the complexity of some
of the circuits in the M876 electrical system, it is necessary to use more than one diagram to identify all components
present in the circuits.
Each functional diagram is keyed to a major component locator to aid in locating the components in
each circuit.
