Electric Assist Choke: Description

All Light Duty emission models use an electrically heated choke thermostat spring housing as an aid to fast choke release. The heater operates from a stator terminal on the alternator. Electrical power is supplied to the choke housing when the engine is running. The choke system consists of a choke cap, thermostatic spring, a bimetallic temperature sensing disc and a Positive Temperature Coefficient (PTC) ceramic heater.
