Common ME-AGS-S Generator Wiring Diagrams
The most common generator starting/run/stop circuits can be
divided into three major types: two-wire, three-wire “momentary”,
or three-wire “maintain”. See Figures 2-9 through 2-12 for examples.
Info:
The term “three-wire” refers to the minimum number
of wires required to control the starter motor and to run the
generator—more than three wires may actually be needed.
