communication Dynamo charging system The fault diagnosis

(1) without a charge

Nature: generator power generation or the charging circuit have open circuit fault

(2) the charging current is too small

Nature: lack of generator power output or output voltage is low

(3) the charging current is too large

Nature: the generator output voltage is on the high side

(4) charging current instability

Nature: generator output voltage instability or charging line contact undesirable

(5) alternator has sound

Nature: generator and components abnormal vibration noise
