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.
Generators & Regulators: Description
System consists of 105-amp generator, internal voltage regulator, battery, Powertrain Control Module (PCM), warning indicator, related fuses and wiring. PCM and generator communicate using pulse-width modulated signals. A dedicated line communicates desired charging rate from PCM to generator and a second dedicated line communicates load from generator to PCM.
Warning indicator should illuminate with ignition on, engine off. Warning indicator should not illuminate with ignition off, or with engine running. Generator and regulator cannot be serviced separately, and must be replaced as an assembly.
