IMPORTANT:
Always zero out the DMM before taking a resistance measurement in order to ensure an accurate reading.
- Disconnect the negative battery cable.
- Disconnect the antenna lead-in connector from the radio receiver.
- Measure the resistance from the negative battery cable to the coaxial cable, outer conductor, connector.
- The resistance measured should be 0.20 ohms or less.
- Test the following when the resistance is greater than 0.20 ohms.
- Base of the antenna for a poor connection to body ground.
- The coaxial cable interconnects for a poor connection or corrosion.
- Test for an open or high resistance from the battery negative cable to the body. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems.
- After finding and correcting the condition, operate the system in order to verify the repair.
