1978–1999 Beechcraft Bonanza F33A, F33C, V35B, A36, A36TC, and B36TC Wiring Diagram Manual (P/N 35-590102-9E1)

This wiring diagram manual covers the 1978–1999 Beechcraft Bonanza F33A, F33C, V35B, A36, A36TC, and B36TC within the serial ranges listed above. Raytheon Aircraft publication P/N 35-590102-9E1 is revised January 29, 1999.

• Electrical power: Alternator, voltage regulator, external power, subpanel distribution, and optional emergency power circuits for single and dual navigation/communications installations.

• Flight controls and landing gear: Elevator trim, flap motors and position indicators, stall warning, gear motors and relays, position indication, and optional landing gear safety systems.

• Fuel and engine circuits: Auxiliary fuel pumps, fuel-quantity and fuel-flow indication, ignition switching, engine instrument clusters, and turbine intake temperature indication.

• Environmental and ice protection systems: Optional air-conditioning and fresh-air blower wiring, heated pitot circuits, and propeller anti-ice connections.

• Lighting: Annunciator and test circuits, instrument-light dimming, electroluminous panels, cabin lights, rotating beacons, and three-light strobe systems.

• Navigation and communications: Turn-coordinator and standby air pump gyro circuits, microphone-switch and cabin-speaker wiring, and emergency locator transmitter connections.

This manual is suited to aircraft maintenance technicians familiar with electrical schematics, wire identification, and connector pin references.

Circuit Tracing and Electrical References

Electrical documentation is organized by ATA-style system chapters, with standardized numbering for systems, subsystems, and individual components. The introduction explains reference designators using examples such as CB101 for a circuit breaker.

The Reference Designator Index and Part Number Index connect component identifiers and part numbers to the relevant chapters. Equipment lists add installation zones, helping a technician identify the corresponding relay, switch, or breaker while tracing an electrical fault.

Aircraft Zone Diagrams locate components around the firewall, main spar, fuselage, empennage, and wings. Electrical Symbols, Basic Contact Switch Assemblies, and Wire Codes charts explain switch states, AWG wire sizes, and identification suffixes, including phase letters used in AC systems.

Drawing scope: The drawings show point-to-point electrical connections; physical wire routing is outside their stated scope. Separate Bonanza shop and maintenance manuals are listed in the introduction for use alongside this electrical repair reference.

Serial Applicability and Equipment Changes

Individual diagrams and equipment lists carry serial applicability codes. Chapter-specific lists of effective pages identify circuit configurations and revision dates.

Alternator and fuel-pump variants: Alternator circuits distinguish installations before and after kit 55-3025-1S. A36TC auxiliary fuel-pump diagrams also separate aircraft before and after fuel-system kit 36-9008-1S under Service Bulletin 2033. These distinctions help match the schematic to the aircraft's modification status.

Optional equipment: The manual does not always distinguish standard equipment from options. Some optional-equipment harnesses are installed with wires dead-ended, so a harness shown on a diagram does not by itself establish that the equipment is installed.

Printed Circuit Boards and Connector Charts

Printed Circuit Board Assembly drawings cover annunciator lights, flap position, electrical equipment, and fuel-quantity indication. Annunciator Light Junction Box Assembly diagrams provide related connections and cross-references to internal board components.

Connector charts cover instrument panel grounding (P/J80), Junction Box Disconnect (P/J54), Crossover Disconnect (P/J85), and wing-access connectors. Connector inserts are shown from the rear, an important distinction when matching contact positions to wire references.

Connector tooling: The P/J54 chart specifies insertion/extraction tool 91067-2 and crimp tool 90265-1.

Assembly contents: Equipment lists distinguish individual components from complete assemblies. The introduction cautions that an assembly outline can contain components that are not actually part of the purchased assembly.

Use this document as technical reference material, and have a certified aviation mechanic handle physical work on the aircraft.

Examples of Landing Gear Circuit Protection

Two circuit-breaker ratings illustrate a small part of the electrical detail in this manual.

For the F33C, serial CJ-180 and after, the Landing Gear–Motor and Relay diagram, Configuration 2 (32-30-01), labels CB18 at 5 amps for the landing gear relay circuit and CB19 at 30 amps for the motor circuit. The accompanying equipment list identifies the corresponding breaker parts.

PDF Navigation and Diagram Detail

Text search, bookmarks, and wiring labels: The PDF has an OCR text layer and embedded bookmarks for indexes, chapters, and individual circuits. Recognition errors can affect searches for wire codes and part numbers. Small labels on dense wiring sheets require zooming.

Supplied as one printable, English-language 694-page PDF. The total includes nine title, publication, and revision pages: the title and publisher pages, revision record, effective-revisions list, and five revision-instruction pages.
