(c) Check that the voltage changes smoothly from 0 V
to approx . 5 V .
2 . INSPECT RESISTANCE OF VARIABLE RESISTOR
(a) Disconnect the variable resistor connector .
(b) Using an ohmmeter, measure the resistance
between terminals VC and E2 .
Resistance: 4 - 6 kS 2
(c) Turn the idle mixture adjusting screw fully
counterclockwise .
(d) Connect an ohmmeter to terminals VAF and E2 .
Turn the adjusting screw fully clockwise and check
that the resistance changes from approx . 5 kS2 to
052 .
