Electric Assist Choke: Description

All passenger cars use an electrically heated choke thermostatic spring housing as an aid to fast choke release during engine warm-up. Heaters are of two types, temperature sensitive and constant operating. Both types operate from center top of alternator, only when engine is actually running. Choke system consists of a choke cap, thermostatic spring, bimetallic temperature sensing disc (switch) and a ceramic Positive Temperature Coefficient (PTC) heater.
