I've tried to search for this problem, as I'm sure I'm not the first, but its a tricky one to find, so perhaps someone has seen it before.
died, so I had it 'fixed'. Some mumblings about the stator having failed. It seemed to operate OK for a few weeks, and then it died again. I sent it back and the voltage regulator
was replaced. This time I plugged it back in and the voltage began to rise after a short time, heading beyond 16v when I stopped it and removed it. Back again. New regulator
again (I didn't pay..) started off well, 13.5V then after about 1/2 hour I checked - 15.2V.
My understanding is that the regulator is meant to output max about 14.8V, but twice in a row seems to suggest that there's something else wrong with my setup. Any ideas?
