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.
Generator "L" Light Circuit (Charge Indicator)
The charge indicator is a LED located in the I/P cluster. It receives battery voltage when the ignition is in the RUN position. The circuit is grounded through the L terminal of the generator With the ignition ON, engine OFF, the generator will ground the generator "L" terminal circuit through a resistor when the regulator detects sense voltage below 9.5 volts or when no AC voltage is detected. When the engine is started and the generator begins to charge, the generator will open the circuit (still using the control voltage) signaling to the PCM that the generator is charging. If the voltage at the control module generator "L" terminal is low when the engine is running, the control module will send a message to the instrument panel cluster to illuminate the charge telltale.

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.
