Hey mate, all those things, starter, glows and headlights are high current draw items. That sounds more and more like a corrosion / high resistance earth problem to me. There is almost certainly a loose or corroded join or joints somewhere. Check your battery terminals for tightness and good contact. It is possible but not probable that the battery itself is high resistance internally. @Yendor, have you got any input mate?

I think you have it pretty well covered. It sounds like either dirty battery terminals, stuffed battery or a high resistance in the main earth from the battery to the body.

The only thing that's not real clear is, had any of the main fuses blown?
