HEATING / AIR CONDITIONING: AIR CONDITIONING SYSTEM (for Automatic Air Conditioning System): Generator Signal Circuit
- Generator Signal Circuit

DESCRIPTION

When the engine is started, the generator rotates and a pulsed voltage signal is generated. This signal is used by the air conditioning amplifier. The generated voltage signals sent from the generator are used for controlling the number of the heater elements to be heated.
