i'm noticing all the lights on the car ( in sig- i.e. dashboard lights, head lights, tail lights etc etc) dimming up and down in time to the engine.
the radio, even when playing a cassette also blips between sound and 'mute' but only when the cars moving. when its stationary e.g. at trafffic lights with the engine going its absolutely fine, so its not the aerial. a mobile phone kit was inside the car when i got it- could this be messing it up?
