I had always assumed that the engine and all components on it were earthed by the very substantial cable fastened to the block just by the left-handengine mounting. But that is not true. That cable does not earth the electrical components running off the engine, it ensures that the starter motor has a good connection to battery negative.
That apparently is not the same thing as earthing the block, hence the braided wire between the valve cover and the bulkhead. This too was corroded at the bulkhead bolt.
Anyway, and attending to all these points the engine sprang into life and ran more smoothly than it has for some time.

Good information,
the earths always seem to be the last thing to check,
I guess on some cars they never give trouble for the whole life of the car.
