Electrical Noise In My Stereo
Can anybody out there give me some ideas to help me cure a persistent electrical noise in my stereo.I have tried all sorts of "noise filters" that
have only slightly helped.Mainly a problem when listening to the radio.
Thanks in advance

Make sure the outer braid of the antenna cable is earthed..
This shield is there to stop noise but must be earthed...
Make sure the Radio is earthed... I suppose it must be earthed somewhere otherwise it wouldn't work....
You could add an earth wire from the engine to chassis, and make sure the earth braid strap at the front of the gearbox is attached both ends.. take
off and polish clean the braid ends plus where it attaches.... wire brush bolts also....
If the noise goes up & down with engine speed its the Generator... Do You have a condensor fitted to the Generator.... if its a popping sound its
the spark plug high voltage side of the ignition....
In army Radio Vehicles everywire was covered with metal shielding connected to earth.. even the spark plug leads and distributor were covered with
metal and earthed to shield out the interference...
I tried many things on a type 3 & Beetle back in the 70s with CBs to stop ignition & generator noise... never really succeded fully...
switched over to electronic mods to speaker to cut down the noise... wouldn't work to well with a radio...
If everything is connected to an earth.. with the earth lead as short as possible... You May succeed...
I have put an alternator in My Beetle so I won't have generator interference... with My Ham Radio gear..
Best of Luck

also can be battery related. My car had a dud battery (ie it was only supplying 7-8v) so the radio had a hard time...the car worked ok though

You could try a coaxial capacitor - the power flows thru the capacitor which cancels out noise coming from the generator.

Lee,
What's a coaxial capacitor and where do they congregate(where can I get one)
Anthiron,
No amp,will check my earths though.
Bones,
Tried noise filters/supressors, no real luck.
Donk,
Battery is sweet.
Thanks all
Anymore sugestions are most welcome,I am trying to get this sorted out before I go to the trouble of putting in amp/sub combo

Try replacing your sparkplug leads with silicon style ones.
