- Inspect the ground terminal and cable for high resistance.
- Inspect the generator and brackets for loose or coated mounting bolts.
- Inspect that the ground straps between the engine and the frame are clean and tight.
- If the noise is still present, inspect the charging system for proper operation. Refer to Symptoms - Engine Electrical .
- Install filter GM P/N 1224205 in the battery voltage feed circuit to the radio.
- If the noise is still present, install the filter in each of the following variations:
- Install the filter with the single wire side toward the radio and the ground wire attached to chassis ground.
- Remove the ground to the filter.
- Reverse the filter so the two wire side is toward the radio with the ground wire attached to chassis ground.
- Remove the ground from the filter.
- If the installation of this filter causes a delay when turning the radio ON or OFF, or other noticeable performance problems, remove the filter and install a 0.47 micro farad capacitor (P/N 1227894) to chassis ground.
- Before reassembling the vehicle, remove any unneeded filters.
- Test the functionality of all the vehicle systems, including those not related to the audio system, for proper operation and function.
