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😎

do you have an amp?......cheap amps can do this. also is your earth good?

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

Get yourself a noise suppressor, there abou $30? from any stero store. I had the same problem in my T3 Ute.
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

im sorry mate i dont know any one in taree to send you to see about it any more. and i wouldn't touch hawkins with a barge pole ( theres some bad blood between them and i). have you tried autobarn in town for a coaxial capacitor( it should be on the shelf next to the flux capacitor)

Hey Barls isnt a flux capacitor what the Doc in Back To The Future used to create his time machine? Didnt realise you could get these at autobarn, now all I need is astainless steel beetle and a shitload of plutonium and I'm away.Who's for a ride?::duh

Try replacing your sparkplug leads with silicon style ones.
