2. When the generator itself or the ambient temperature are too high, the specified current
also cannot be verified. In this case, cool down the generator and recheck.
10. Turn the electrical loads (headlights, blower motor, rear window defroster, brake lights, etc.) on and
verify that the current reading increases more than the minimum value indicated below.
1. If it is not as specified, go to the PCM and generator shearing inspection. (See
generator shearing
NOTE:
Current required for generating power varies with the electrical loads applied.
Generator generated current (reference value) [Conditions] Ambient temperature: 20 °C {68 °F},
Voltage: 13—15 V, Engine hot
