2. Touch one ohmmeter test lead to the tip of the antenna mast. Touch the other test lead to the antenna cap nut. Check the ohmmeter reading for continuity. 3. There should be no continuity. If OK, go to Test 2. If not OK, replace the faulty antenna body and cable. TEST 2 Test 2 checks the antenna conductor components for an open circuit. This test should be performed first on the 1. Disconnect the instrument panel (secondary) antenna cable coaxial connector from the back of the radio. 2. Touch one ohmmeter test lead to the tip of the antenna mast. Touch the other test lead to the center conductor pin of the instrument panel antenna cable coaxial connector for the radio. Check the ohmmeter reading for con- 3. There should be continuity. The ohmmeter should register only a fraction of an ohm resistance. High or infinite resistance indicates a damaged or open antenna conductor. If OK, go to Test 3. If not OK, isolate and test each TEST 3 Test 3 checks the condition of the vehicle body ground connection. To begin this test, proceed as follows: 1. This test must be performed with the battery positive cable disconnected from the battery. Disconnect and isolate both battery cables, negative cable first. 2. Reconnect the battery negative cable. 3. Touch one ohmmeter test lead to a good clean ground point on the vehicle fender. Touch the other test lead to the battery negative terminal post. Check the ohmmeter reading for continuity. 4. There should be continuity. The ohmmeter should register less than one ohm resistance. High or infinite resis- tance indicates a loose, corroded, or damaged connection between the battery negative terminal and the vehicle TEST 4 Test 4 checks the condition of the connection between the antenna coaxial cable shield and the vehicle body ground 1. Disconnect and isolate the antenna coaxial cable connector under the right end of the instrument panel near the right cowl side inner panel. 2. Touch one ohmmeter test lead to a good clean ground point on the vehicle fender. Touch the other test lead to the outer crimp on the antenna coaxial cable connector under the right end of the instrument panel near the right 3. There should be continuity. The ohmmeter should register less than one ohm resistance. High or infinite resis- tance indicates a loose, corroded, or damaged connection between the antenna body and the vehicle body or 4. Check the resistance again with an ohmmeter. If the resistance is still more then one ohm, replace the faulty antenna body and cable. 8A - 168 AUDIO/VIDEO - SERVICE INFORMATION WK |
