1. Check Radio reception in an area away from tall buildings, metal structures, power lines, fluorescent lighting and power tools.
2. Ignition noise on FM indicates a possible defective Electronic Ignition (EI) System. Refer to Starting and Charging. Starting and Charging
3. Check antenna coax connectors for corrosion or bad connections.
4. If a test antenna is used, ground the base of the antenna to the vehicle body.
5. Coated screws or bolts can act as poor grounds.
