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-Fig.

Use a “Dr. Robin” in capacitance meter mode to check the capacity of condensers. (See

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