Inspect the light control rheostat.

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

Standard Resistance:

Tester Connection	Switch Condition	Specified Condition
9 (T) - 6 (E)	Always	10 +/-2 kΩ
7 (TR) - 6 (E)	Knob turned fully upward	10 +/-2 kΩ
7 (TR) - 6 (E)	Knob turned fully downward	Below 50 Ω
7 (TR) - 6 (E)	Knob turned from fully upward to fully downward	10 +/-2 kΩ → Below 50 Ω

If the result is not as specified, replace the light control rheostat.

Inspect the TAIL cancel switch.

HINT:: The TAIL cancel switch is built into the light control rheostat.

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

Standard Resistance:

Tester Connection	Switch Condition	Specified Condition
9 (T) - 8 (TC)	Knob turned fully upward (TAIL cancel condition)	10 kΩ or higher
9 (T) - 8 (TC)	Knob not turned fully upward	Below 1 Ω

If the result is not as specified, replace the light control rheostat.
