You have made the comment that may have it sorted " it's done nothing since the rewind"

The field poles have lost the residual magnetic flux

That is needed to get it to output the volts locate the field coils wires and with a car headlamp bulb in series with them and a 12 volt battery just connect them for a couple of seconds


This can happen with all DC genneys Evan a clout with a hammer can demagogue them enought to stop them performing

Wot Kev said! I am not familiar with the tiny tim, but if it is a DC generator like a dynamo, and hasn't been used for twenty years, I can almost garuntee the only problem is that it has lost its residual magnetism, and without that it wont start to generate current. Have you an autoelectrician near you that you could show it to? It is literally a five minute fix.

Krv is pretty good with motors ect
