NOTE 1: Because a diode is soldered to the coil
ends at the terminals, resistance may
be measured only when tester probes
touche the terminals in one
combi-
nation of polarity. Therefore, if no re-
sistance reading appears, try checking
in reverse polarity.
NOTE 2: If the circuit tester is not sufficiently
accurate, it may not show the values
given and may give
erroneous
readings.
Erroneous reading will also occur when
there is a wide variation of resistance
among coil windings or when meas-
urement is performed at embient tem-
peratures ditferent from 20°C(68”F).

9-5 CONDENSER
Use a “Dr. Robin” in capacitance meter mode to check the capacity of condensers. (See Fig.9-6).

NOTE: Be sure to discharge condensers by shorting condenser leads each other before checking their
capacitance,or the accurate reading cannot be obtained.
