I have to be honest, these vehicle aren't sold in N, America, so I have limited knowledge and no shop manuals for it. However, I am going to try my best to help.
Can you tell me if the alternator has a regulator built into it or if the voltage is regulated by the power control module? Also, are battery terminals clean and tight? Is the alt belt tight? When the light comes on, have you checked to see if the alternator is still charging the battery? Last, are you certain that the main ground to the engine block from the battery is in good condition, tight and clean?
