Bill, I'm definitely not a Spitfire expert, but here's some comments that
might help :

Have you tried changing the oil ? If the pressure relief valve is
accessible, I'd pull it out for a clean and inspect next.

First, find and fix the bad connection causing the voltmeter swing. If you
don't already have one, get a cheap DMM from Harbor Freight. Then try
repolarizing the generator. Although it's not likely to help, they do
sometimes 'lose it'. However, the red light should be on if that's the
problem.
The lack of high beams is yet another problem.

Zenith/Strombergs, right ? Check the diaphragms.

Sorry, I know I've read how to seal them, but durned if I can recall.
