RAM 1500 Truck 4WD V8-5.9L VIN Z (2002)
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 resistance indicates a loose, corroded, or
damaged connection between the battery negative terminal and the vehicle body. If OK, go to Test 4. If not OK, check the battery negative cable
connection to the vehicle body and the radio noise suppression ground strap connections to the engine and the vehicle body for being loose or
corroded. Clean or tighten these connections as required.
TEST 4
Test 4 checks the condition of the connection between the antenna coaxial cable shield and the vehicle body ground as follows:
1. Disconnect and isolate the antenna coaxial cable connector behind the right side kick 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. Check the ohmmeter reading for continuity.
3. There should be continuity The ohmmeter should register less than one ohm resistance. High or infinite resistance indicates a loose, corroded, or
damaged connection between the antenna body and the vehicle body or between the antenna body and the antenna coaxial cable shield. If not OK,
clean the antenna body to fender mating surfaces and tighten the antenna cap nut to specifications.
4. Check the resistance again with an ohmmeter. If the resistance is still more then one ohm, replace the faulty antenna body and cable.
