I thought i would post this since i actually solved an electrical gremlin for once. :shock:
The problem was a charging light (RGM type) which rarely went off and not at consisitent revs, might even go off for a while and then come on again at same revs - but the battery did not go flat although i was sometimes getting some kick back on cold starting (Boyer MkIII) and i was not using the lights much. Checking across the battery with a multimeter showed the charging light to be correct, rarely above 12.5V at any revs.
This was found to be the culprit - the fuse had a scrap of metal (part of the wire cap that came off?) between its base and the cap on the wire, which seemed to be getting hot and trying to escape out the side of the fuse holder. I replaced it with a blade type fuse because the pictured fuse holder could not be opened and because the blade type are more easily bought - and instant success.
Dissection after removal showed the source of the problem.
