DESCRIPTION & OPERATION
The generator has a built-in regulator with diagnostic functions and voltage regulating functions, such as the following
- Voltage regulation: The On-Off operation of transistor TR 1 connects and disconnects the field current circuit which provides a constant output voltage level. (Scheme 2)
- Diagnosis warning is when any of the following problems occur the charge lamp illuminates: No voltage generation: Brush wear exceeds specified wear limits, field coil circuit is broken, etc. Excessive output: Output voltage is greater than 16 volts (approximately.) Terminal B disconnection: Harness is disconnected from alternator terminal B. Terminal S disconnection: Harness is disconnected from alternator terminal S. In this case, voltage is slightly greater than specified regulated voltage; however, voltage regulation is still controlled and the battery is prevented from overcharging.
