Dynamo woes

[Ian Williams]

A lot of dynamos are rebuildable Joe, try re connecting the broken wires and testing the windings, if they are good it should work. The commutator can be lightly skimmed in a lathe, bearings replaced if worn, watch out for the little cotton reel type insulators on the brush spring posts, they go brittle and break are often missing causing a short and on a faulty dynamo are sometimes the only reason it wont charge. I would have thought Tony Betts would be a good source of a replacement unit or parts if you need them. There were people like Vince Leek who rebuilt them on exchange basis, not sure if anyone still offers this service in the UK.
