      *1	Connector A
      *2	Connector B
      *3	Connector C
      *a	Component without harness connected (Quick Heater Assembly)

      for 840W:

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition A-1 - B-1 23 to 25°C (73 to 77°F) 0.5 to 2.5 Ω A-2 - B-1 23 to 25°C (73 to 77°F) 0.5 to 2.5 Ω A-2 - C-1 23 to 25°C (73 to 77°F) 0.5 to 2.5 Ω A-3 - C-1 23 to 25°C (73 to 77°F) 0.5 to 2.5 Ω

      If the result is not as specified, replace the quick heater assembly.
