Help woth noisy stereo

From your description, the first thing I would try is to check the aerial cable for damage, joins etc. and try rerouting the aerial lead, you might even need a new aerial.

Failing that, doesn't he need a suppressor choke on the ignition circuit? Usually sold at Halfrauds, or similar for an outrageous few quid (no, they're really worth pennies) but with instructions for fitting that your granny could follow.

Do you have the in-glass windshield 'active' antenna system? If so, it's possible that when the CD player/radio was fitted, the installer forgot to reconnect power to the pre-amplifier. If the pre-amp is unpowered FM reception will be poor and AM reception non-existant.

Hi Ian,

No. The aerial is front wing-mounted. I guess that is why God invented bank holidays - so I will be checking out aerial lead, route through car body, supressor and as a last resort replace plug leads.

Thanks to everyone for their advice.

Cheers Mark

Mark, if you find the antenna cable to be OK, and resort to supressors as per the Halfords advice, here is how to select the right type. If you interference is a medium to high pitched whine, then the alternator is the source. If the interference is a clicking at tick over rising to a few hundred hertz (clicks per second) then fit ignition suppressors or suppressed plug leads.

Good luck

Bob

Don't you get spark plugs with an "S" in their reference number to denote that they are suppressed? mebbe a set of them will do the trick
