Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation
The Mitsubishi generator is a conventional rotating field, 3-phase, self-rectifying type. Four positive and 4 negative diodes are used to rectify current. System is equipped with built-in voltage regulator which controls output voltage and warning light operation.
The on-off operation of transistor Tr1 connects and disconnects the field current flow, providing a constant level of output voltage. See WIRING DIAGRAMS .
When any of the following problems occur, the charge light will illuminate:
- No voltage generation: brush wear exceeds specified limits, field coil circuit is broken.
- Excessive output: output voltage is greater than about 16 volts.
- Harness is disconnected from generator terminal "B".
- Harness is disconnected from generator terminal "S". In this case, voltage is slightly greater than specified regulated voltage. However, voltage regulation is still controlled and battery is prevented from being overcharged.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
