SECTION 20
WIRING AND SCHEMATIC DIAGRAMS
1. Wiring and Schematic Diagram
(4). The following letter indicates segment
of wire in a wire number where the
wire passes through or branches at a
connector or terminal block.
Wiring and schematic diagrams for the
electrical system of the helicopter are provided
in this section. Wire identification and symbol
information for the diagrams are also included.
(5). The number (or numbers) following the
segment designation is the standard
AWG wire size.
A. Wire Identification
Wiring in the helicopter is identified by code of
numbers and letters at intervals throughout
the wire length. The wiring indemnification
code is as follows:
(6). If the wire is a ground portion of a
circuit, the suffix N is added to indicate
a ground return.
(7). Where a wire code is duplicated, the
unit number 1 or 2 is prefixed to
differentiate between the two circuits.
(1). The initial number (is used) designates
unit number.
(2). The initial letter (or letters) designates
the circuit.
(3). The next number (or numbers) is the
wire number that separates one section
or leg of the circuit from all others.
B. Symbols
The graphic electrical symbols in the schemat­
ic, and in the wiring diagrams where symbols
are used for clarity, are shown in Figure 20-1.

500 Series - Basic HMI
C. Diagrams
The electrical system wiring diagrams,
Figure 20-2 thru Figure 20-11, provide wiring
information for the basic electrical system.
Wiring diagram application versus helicopter
model serial number is shown in the title of
each diagram and is listed below.
The wiring diagram show complete point-topoint wiring interconnections between all basic
electrical system components.
The electrical system schematic diagrams,
Figure 20-14 thru Figure 20-16, schematically
show typical electrical system for helicopters
with instrument panel types A, B and normal
CSP-H-2
version 500M helicopter with instrument
panel type T.
Electrical system diagrams for special versions
of the 500M are provided in Section 20 of the
appropriate part of the 500M HMI Supple­
ment.
Electrical diagrams for optional equipment are
furnished in the applicable equipment group of
HMI Appendix A.
D. Reference Designator List
Table 20-1 contains a list of electrical equip­
ment items used in the helicopter and shown

VARIATIONS MAY EXIST FROM THAT SHOWN DEPENDING ON
HELICOPTER MODEL. (REFERENCE DESIGNATORS, COMPONENT
VALUES, CONNECTOR PINS, TERMINAL NUMBERS, ETC. MAY VARY.)
2. FOR IDENTIFICATION OF CIRCUIT INTERCONNECTION THROUGH
MAJOR COMPONENTS, USE THIS DIAGRAM WITH THE APPROPRIATE
COMPONENT INTERNAL SCHEMATICS AND WIRING DIAGRAMS THAT
ARE PRESENTED IN OTHER SECTIONS OF THIS MANUAL.
3. NOT ALL OPTIONAL EQUIPMENT IS SHOWN. ASTERISK ( * ) INDICATES
OPTIONAL EQUIPMENT FOR MOST MODELS. FOR ELECTRICAL WIRING
DIAGRAMS OF OPTIONAL EQUIPMENT, REFER TO CSP-H-3, APPENDIX A.
4. INSTRUMENT CLUSTER 4 PACK CIRCUIT, SHOWN SEPARATELY, IS USED
ON HELICOPTERS WITH P/N 6460013 OIL PRESSURE SENDER.

NOTES:
1. THIS DIAGRAM IS PRESENTED AS A TYPICAL BASIC ELECTRICAL
SYSTEM FOR A HELICOPTER WITH INSTRUMENT PANEL TYPE B.
VARIATIONS MAY EXIST FROM THAT SHOWN DEPENDING ON
HELICOPTER MODEL AND SERIAL NO. (REFERENCE DESIGNATORS,
COMPONENT VALUES, CONNECTOR PINS, TERMINAL NUMBERS,
ETC. MAY VARY.)
2. FOR IDENTIFICATION OF CIRCUIT INTERCONNECTION THROUGH
MAJOR COMPONENTS, USE THIS DIAGRAM WITH THE APPROPRIATE
COMPONENT INTERNAL SCHEMATICS AND WIRING DIAGRAMS THAT
ARE PRESENTED IN OTHER SECTIONS OF THIS MANUAL.
3. OPTIONAL EQUIPMENT AND ALL PROVISIONS FOR OPTIONAL
EQUIPMENT ARE NOT SHOWN. ASTERISK ( * ) INDICATES OPTIONAL
EQUIPMENT FOR MOST MODELS. FOR ELECTRICAL WIRING
DIAGRAMS OF OPTIONAL EQUIPMENT, REFER TO CSP-H-3,

4. USED ON HELICOPTER WITH 250-C20 ENGINE;
NOT USED WITH 250-C18 ENGINE.
5. UNIT AND INTERCONNECTION WIRING DIFFERS ON HELICOPTER
WITH 250-C18 ENGINE AND WITHOUT NR SENSING EQUIPMENT
(INCLUDING NR DISABLE SWITCH S199).
6. OPTIONAL ON EARLY HELICOPTERS.
7. FOR 4-PACK INSTRUMENT CLUSTER DIFFERENCES, REFER TO
SEC. 17.
8. PIN H FOR UNIT WITHOUT NR SENSING (REF. SEC. 19).
9. NOT USED FOR UNIT WITHOUT NR SENSING (REF. SEC. 17).
10. TERMINALS SHOWN ARE FOR NON-DIMMING LIGHT INDICATORS.
FOR DIMMING LIGHT INDICATORS, TERMINAL C APPLIES WHERE 3 IS
