Electrical System parts and their functions

12 top-level parts · 4,240 parts in total · full bill of materials below

#	Part	Qty	What it does
1	Starter-Generator	1×	starter-generator
2	12 V Battery	1×	12 V lead-acid or lithium battery that powers the vehicle's low-voltage electronics and starts or wakes the main system.
3	Wire Bundle	2×	Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
4	Connector	180×	Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
5	Insulated Wire (cut length)	1200×	One cut-to-length insulated conductor in the harness, terminated at both ends.
6	Crimp Terminal	2400×	two per wire
7	Circuit Breaker	60×	Resettable breaker on the overhead or console panel.
8	Relay	20×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
9	Exterior Light	7×	Position, anti-collision, landing or search light.
10	Pitot Tube & Heater	1×	Heated pitot probe.
11	Antenna	8×	VHF, GPS, transponder, ELT or radar altimeter antenna.
12	Cable Tie & Clamp	360×	Tie, P-clip or saddle clamp securing wiring, hoses and lines to the structure.
