Simon. I'm now realising my internal derusting and cleaning out with diesel (of a really skanky dynamo) wasn't perhaps my best idea... its presently sitting on the top of the woodburner for a few days and I'll do the tests again and see if I can identify fault before sending away. The annoying thing is that it's still easy enough to find another working dynamo rather than embarking on having the expensive work done. I'm nearly at the stage where I'm starting to appreciate just doing the latter so one is equipped for a trouble-free future!
