i connected the filter to ACC from the wireharness and then from the filter to the cd player. the alternator is a reco one from the wreckers. the coil and alternator have a little cylinder resitor on the both. the car is earthed from the battery, engine and trans. but it is weird when i connected the new filter it made the problem worse.
I cant find the problem someone help.!

Two Questions nizzdat. 1. how did you wire the power on to Example Battery or passing power lead under the dash? mining No offence ok. 2. How old is alternator, is there a filter on it? If is what condition is it in. This is a common problem with my datos and l put new filters on coil, alternator & earthed the bonnet (Earth strap) and dissy. Why? Because l have cb's in my two dato's as well and they all picking static up as well the radio. GooD Luck with finding it. Bruns

In my g/f 1200 when the engine is running the music from the cd player keeps cutting in and out, like a static noise. It is a Pioneer CD player (PIODEH1600) with new Kenwood 6x9's. i installed a aepro noise filter but the problem is now worse than before. I have earthed the noise filter properly and connected to the battery but no difference. Can any one help.

Cheers
Ryan
