Would help if you said what the problem is - steroes are not caused by earth leads.

Basically, you have to track down which of the many earth points is actually causing the problem. A multi meter and/or a continuity tester will help.

Then I got called by SWMBO to go out for a while.

Obvious starting points are the battery earth lead connection - always worth taking it off, cleaning and reattaching. Then the radio will have a live (power) lead and an earth lead - again check the earth lead. Is the aerial lead making a good contact where it bolts in to rear wing. Is the aerial lead plugged fully in to the rear of the radio.

Are you getting interference on reception that speeds up when the engine speed is increased ? Possible cause is a breakdown in the ignition supressors.

May be worth going back to who ever suggested an earth problem and asking them for a bit for detail.
