Rear Light Warning System
1.Stop lights and Hi-mounted stop light open circuit
When the stop lights and hi-mounted stop light are operating normally, the voltage of comparators 1 and 2 on the positive side when the lights are Read more Rear Light Warning System
Front and Rear Fog Light System
1.Front fog light operation
The front fog light operates when the light control switch is in the TAIL or HEAD position. When the front fog light switch is moved one click to the ON position, the front Read more Front and Rear Fog Light System
Turn Signal and Hazard Warning System
1.Turn signal light operation
When the turn signal switch is operated, the turn signal flasher switches the turn signal light LH or RH and it flashes.
To make the driver aware of the operation, an operating Read more Turn Signal and Hazard Warning System
Headlight and Taillight System
1.Taillight system
There are two types of taillight system: a type in which the taillight is directly connected to the light control switch and a type with a taillight relay.
(1)Directly connected type
When Read more Headlight and Taillight System
Automotive Lighting System
Lights used for vehicles are classified according to the purpose: for illumination, signaling or informing. For example, headlights are used for illumination to see at night, turn signal lights for signaling Read more Automotive Lighting System
Inspection in Charging System
1.No-load test (inspect charging circuit without load)
In the no-load test, whether the generated voltage is maintained at a constant level (regulated voltage) is cheeked even if the alternator speed Read more Inspection in Charging System
SC Type Automotive Alternator
An SC type alternator adopts a joined segment conductor system (insert the segment conductor and weld it) to the stator winding method. This type of alternator can reduce the resistance value by half comparing Read more SC Type Automotive Alternator
Automotive Output Control by IC Regulator
The following explains the mechanism by which the IC regulator keeps the generated voltage constant and how it operates to achieve this function using a battery sensing type IC regulator as an example.
1.Normal Read more Automotive Output Control by IC Regulator
Regulate Generated Electricity
Self-control for maximum output current
A characteristic of the alternator is that the output current flows almost constant when it exceeds a certain speed (self-control operation).
Therefore, when Read more Regulate Generated Electricity
