Ok Derek...with you on that until the last bit...How do I test for the Earthing out you mention?

Harv,
With the alternator wires disconnected, set your meter to read resistance (ohms) and connect one lead to a good earth point on the frame and the other to each of the yellow alternator leads in turn. Do NOT run the engine. None of them should show any ohms to earth.
If you got no volts out of the alternator at all when you tested it you could also connect the meter across the 2 yellow wires and measure the resistance. There should be a fairly low resistance of maybe 4 or 5 ohms. If there is zero ohms then the windings are short circuit, so no output. If you get infinite resistance the the stator is open circuit, also with no output.
Hope this helps.
