When checking coil resistance, use an analog-
type multimeter.
For an accurate ohms reading, perform this
check when the system is at room
temperature. Heat will increase resistance,
resulting in a higher ohms reading.
Replace control valve (para. 8-25).

1. Bet the vottmeter to an ohms scale of about
1 .OW ohms.
2. Connect the RED and BLACK leads to the
connections stated in the question.
3. Be sure to read the correct scale. Less than 5
ohms indicates continuity.
For an open circuit,
the meter should peg full scale (needle all the
way to the left).
