Thank you Al Patrick for your nice reply:
Be sure you hood and trunk are grounded well to the main body of the auto. This is usually done with a short piece of flexible copper web, well secured at each end. I have already checked it. It is grounded quite firm with a very thick cable. You should be able to tell the difference in ignition noise and alternator noise, the alternator noise is more of a whine but with varying pitch as the engine revs up. If it is ignition, you can get resistor plugs which are supposed to help. There is also supposed to be a resistor that can be installed for the alternator whine. noise is coming from ignition and there is another continious noise i couldn't find the origin. There is somthing the technicians call "brain" here in Istanbul, I don't know what is it called in English. It seems that the noise is coming from that part. by the way, alternator already has a resistor. It is often VERY difficult to solve. I've heard of people purchasing a car based on how quite the radio is on MW / AM. You'd be surprised the differences in this on new cars of the same make, model, etc. I learned it iss very difficult by my own experience. I tried VW polo and golf cars and produced in 2000 and 1999, some has enormous noise, some has a little and some has no noise at all. All with their original blaupunkt radios. Impossible to believe. And I know by heart, I will test it's radio's MW and LW band reception obsessively before I buy a new car, If I will. Regards, oan |
