TEST 91
1. Connect RED clip and BLACK clip to the
terminations
indicated in the question.
RED to
the first, BLACK to the second.
2. Start Test 91.0-4.500
Ohms.

Replace control valve ( para. 8 25).
CONTINUITY (RESISTANCE)
MULTIMETER
1. Set the voltmeter to an ohms scale of about
1,000 ohms.
2. Connect the RED and BLACK leads to the
connections
stated in the question.
3. Be sure to read the correct scale.
