This is may alternator problem, but can you explain exactly.
Condition stationer rpm, voltage of alternator same with batery (12V), it mean not charge or less capacity. if rpm increase, voltage can increase to 13.5 V (can charge batery). What is the problem? The alternator just 1 year. Before stationer or high rpm the voltage stable between 13.5 V - 14,5 V
