Component Tests and General Diagnostics

Perform before beginning System Diagnosis
1. Check Fuses7 and 8 in 1/P Fuse Block. If open, refer to Chart #3. Chart 3 Courtesy Fuse B Continues to Blow Fuses
2. Check for a poor connection at G200.
3. If the Transmitter fails to operate from a normal distance, up to 7 to 10 meters (22 to 33 ft.), check for two conditions: weak batteries in Transmitter (expected life approximately 2 years depending on use); or close proximity to a Radio Transmitter, such as a Radio Station Tower, airport Transmitter, and some mobile or CB Radios.
4. Try a second Transmitter if available. If the second Transmitter works, remove the Battery and install the Battery in the original Transmitter. Try the original Transmitter again. If the original Transmitter still does not work, it is defective.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
