Hello all, I’m having trouble getting my (early coil) dynamo to behave. After years of satisfactory service the cut out has become reluctant to cut in and then when it does the charging rate is very erratic. It zoomed up to 15amps and jammed the needle on the ammeter on winter charge, but summer charge seems ok. If I force the cut out to close it will charge so I assume the problem is with the regulation and not the Dynamo itself, although the wire to one of the brushes is loose and just held in by friction which probably isn’t helping.
I have the Dynamo apart on my bench, it has thrown a bit of solder due to the overcharging but looks serviceable. my inclination is to clean it up, fit new brushes and go over to 2 brush and electronic regulator. Any thoughts on what could caUse the symptoms and what I should be checking?
