1. Connect the 2P connector (5) to previous position of the alternator after turning the main switch OFF.
2. Start the engine and then set at idling speed.
3. Measure the voltage between the terminal B (2) and the chassis. (Switch off all the lamps)
4. The voltage rises gradually and if it reaches 14V, the alternator is normal.
NOTE
• It takes about 5 to 10 minutes until the voltage value stabilizes
5. If the voltage value does not rise to 14V, the alternator is faulty.
Replace the alternator.
(Reference)
• Once the engine has started, the alternator temperature rises quickly up to an ambient temperature of 70 to 90 °C (158 to 194 °F). As the temperature goes higher than 50 °C (122 °F), the alternator voltage slowly drops; at higher than 100 °C (212 °F), it drops by about 1 V.
