WIRE CODES
The wire codes used in the BEECHCRAFT Bonanza closely follow the military numbering system. Each wire and cable are identified by a combination of numbers and letters imprinted on the wire and cable as illustrated in Figure 1. Each wire or cable is identified within 3 inches of each junction. No code is required for short wires or cables less than 3 inches in length. A nonmetalic sleeve carrying identification will appearon wires where imprinted codes cannot be affixed.
Circuit function letters indicate a relationship to a particular system (noted in the list of circuit function designations). Wire numbers are provided to differentiate between wires in acircuit.
A wire segment is a conductor between two terminals orconnections. Alphabetical sequency is usually followed. Wire segment A indicates the power source, B next segment, etc.
The wire size number is used to identify the size of the wire or cable.
A suffix to the wire identification code (N) identifies any wire or cable that completes the circuit to ground network
Phase letter "A", "B" or "C" used as a suffix identifies three-phase wiring in ac systems.
