96.1 ELECTRICAL SYSTEM
96.1.1 Electrical Systems
Maintenance of electrical circuitry, electrical
equipment, and electrical components with the
helicopter is presented in the following systems
text.
Control Panels for AC and DC electrical systems
are located on the overhead console. Control
relays, power relays, voltage regulators, and
other equipment required to control, regulate, and
to effect power transfer and malfunction
monitoring are located in respective
compartments. For equipment location, see
Drawing D212-725-8 or D212-725-8-G2 as
applicable in Appendix A.
NOTE
For location of an item code cited
in the text of the manual and wiring
diagrams, refer to the Equipment
Designator, Nomenclature, and
Location Table 96-1.
Throughout this chapter, when performing
operational checks, external power should be
used whenever possible. Circuit breakers and
switches are considered to be in their normal
position. Perform operational checks after
equipment is replaced or airframe wiring is
repaired or replaced.
96.1.2 Troubleshooting – Electrical
Systems
The maintenance procedures are recommended
as a guide to locate malfunctions in the electrical
systems. Following obvious and/or easiest to
check should be accomplished first. The
following need not be performed in order listed:
96.1.2.1
Progressively check that
electrical power is supplied from power source to
electrical unit. Refer to applicable wiring
diagrams in Chapter 98.
96.1.2.2
Verify that switches, relays, and
diodes are functioning properly.
96.1.2.3
Check that wiring, connectors,
and connections are in normal condition.
96.1.2.4
Verify electrical unit is not
defective.
96.1.3 Effectivity
Effectivity for illustrations and text is indicated
where applicable. When effectivity is not
indicated, all helicopters are covered.
96.1.4 Equipment Reference
Designator, Nomenclature, and Location
Table 96-1 can be used as an aid in
troubleshooting by giving general vicinity of the
item to maintenance personnel. For example, if
the Forward Fuel Interconnect Valve, B17, is
suspected to be defective, locate item B17 in the
REF DES Column of Table 96-1 to determine that
this item is located in “Fuel Cells, lower, forward
of”.
