Choke Cap Resistor Test

1. Hold a 100-watt lighted extension lamp against the face of the choke cap for three to five minutes to assure the choke cap has reached a temperature above the internal switching point.

2. With an ohmmeter, set to lowest range that will indicate 30 ohms (maximum). Connect one lead of an ohmmeter to choke cap terminal and the other lead to choke cap shroud. Be sure metal-to-metal contact is achieved (not metal-oxide film) and false readings are prevented. This ohm reading should be under 30 but never zero. If the ohm reading is outside this range, start the test all over. If this improper reading repeats, the choke cap is defective. The cap should be replaced.
