DESCRIPTION & OPERATION
NOTE: The terms generator and alternator are interchangeable.
Mitsubishi generators are conventional 3-phase, self-
rectifying type units containing 6 diodes (3 positive and 3 negative)
which are used to rectify current. All models use a case-mounted
Integrated Circuit (IC) voltage regulator.
Generator relay or resistor with diode is used to ensure
charging of battery even if charging indicator light is defective.
