TEST 2 Test 2 checks the antenna for an open circuit as follows: 1. Disconnect the antenna coaxial cable connector from the radio receiver chassis. 2. Connect one ohmmeter test lead to the antenna mast in the center of the antenna base. Connect the other test lead to the center pin of the antenna coaxial cable connector. 3. Continuity should exist (the ohmmeter should only register a fraction of an ohm). High or infinite resistance indi- cates damage to the base and cable assembly. Replace the faulty base and cable, if required. TEST 3 Test 3 checks the condition of the vehicle body ground connection. This test should be performed with the battery 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the battery negative ter- minal post. 2. The resistance should be less than one ohm. 3. If the resistance is more than one ohm, check the braided ground strap(s) connected to the engine and the vehicle body for being loose, corroded, or damaged. Repair the ground strap connections, if required. TEST 4 Test 4 checks the condition of the ground between the antenna base and the vehicle body as follows: 1. Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the outer crimp on the antenna coaxial cable connector. 2. The resistance should be less then one ohm. 3. If the resistance is more then one ohm, clean and/or tighten the antenna base to fender mounting hardware. REMOVAL 1. Disconnect and isolate the battery negative cable. 2. Remove the right side cowl trim cover. 3. Reach under the instrument panel outboard of the glove box to access and disconnect the antenna 4. Disengage the antenna coaxial cable retainer at the right cowl side inner panel. HB AUDIO/VIDEO - SERVICE INFORMATION 8A - 189 |
