Dynamo and cutout operation are exhaustively covered in posts, including recent, and club info sites.
Care is necessary fiddling with cutout.
If prodded it will normally lock operated. Must not be left like this . Pull open and/or disconnect battery.
It is vital that the input side of the cutout is not directly earthed, as by the wires from D or F terminals on cutout lying about unconnected. If cutout then prodded high current from battery to earth may wreck it.
As previous the standard test for dynamo is to remove both leads, link the terminals and connect link through an old headlamp bulb to earth. As engine revs beyond a brisk idle lamp should commence to light very bright.
