Earth wire for Brumby Radio

I've installed a new radio in my Brumby and I get a lot of static when the engine is running. Drives me insane. What do other people do to stop this happening. Mainly on the AM stations.
I have the earth hooked up to the self tapper on the glove box. Shouls it be mounted elsewhere? When the engine is off it is all clear, no static.
Could I run the earth straight off the battery? Would this help? Not real good on electrics.

you need to install a noise filter/ suppressor on the positive power to the stereo
heres an example

Sounds like you're getting interference through your dizzy. I would check that you have a condensor attached to the side of your dizzy. It should look like the pic below...
I'd also change your earth point to near the geaarbox tunnel, like the ring/surround around the gearshifter

Condensor, like for points ? Ain't it called something duifferent ? Got the same interference when I hit the fans on buttons. Sign of the times - getting older and finding better stuff on AM

Well you do live on the East coast and have some funny names for things Jonno
Only other name I've heard them be called is Capacitor but they are most commonly called Condensors.
The old noise suppressors (like what TOONGA posted) are great for clearing out other noises like what you're getting through your wiring. You can make these yourself by wrapping your positive feed to your radio around a donut magnet. Similar to the pic below...

Cant really add much more to this thread because I think that it has all been said. The noise you are getting will probably be from the dizzy and other electrics in the vehicle. Adding a suppressor should get rid of it.

Yeah Gaz, we call them the same but There is 2 things I was talking about in my post. The condenser is on the dizzy and the suppressor is on the power feed to the radio. The suppressor is really not required if you are using clean power and good earths.
