1. A generator control system for a vehicle comprising:an AC generator having a field coil and a rectifying unit;a switch connected in series with said field coil;a voltage regulator unit for regulating output voltage of said AC generator to a predetermined regulation voltage;a field-current restricting unit for restricting current supplied to said field coil, said field-current restricting unit controlling said switch to turn on or off the field current; anda forbidding unit having a command signal input terminal for forbidding operation of said field-current restricting unit when a voltage higher than said predetermined regulation voltage is applied to said command signal input terminal. 2. The generator control system as claimed in claim 1,wherein said forbidding unit disables said field-current restricting unit when the voltage applied to said command signal input terminal is higher than the predetermined regulation voltage for a period longer than a predetermined period. 3. The generator control system as claimed in claim 1,wherein said rectifying unit comprises a plurality of zener diodes having a breakdown voltage, and the voltage applied to said command signal input terminal is higher than said breakdown voltage. 4. The generator control system as claimed in claim 1, further comprising a charge lamp,wherein said command signal input terminal is connected to said charge lamp. 5. The generator control system as claimed in claim 1,wherein said command signal input terminal is an IG-terminal. 6. The generator control system as claimed in claim 1, further comprising a generation-state detecting unit,wherein said command signal input terminal is connected to said generation-state detecting unit. 7. The generator control system as claimed in claim 1, further comprising a generation-characteristic changing unit,wherein said command signal input terminal is connected to said generation-characteristic changing unit. 8. The generator control system as claimed in claim 1, further comprising a battery,wherein said command signal input terminal is connected to said battery.
