Electric Assist Choke: Operation

When ignition switch is turned "ON", power is supplied to temperature control switch. Temperature control switch senses engine temperature and will open or close switch contacts, thereby controlling electric current to choke heater element. Engines started in winter conditions will experience three levels of choke heat; LOW during warm-up, HIGH after engine warm-up and NONE well after engine warm-up. Below 58°F control switch will provide choke heater with partial power. Above 58°F it will provide choke heater with full power. At approximately 110°F it will turn off power. Engines started in summer temperatures will not experience low choke heat level. Engines restarted hot may only experience the no-load condition, since control switch may be warmer than 110°F. The resistor will be hot when in use.
