If it's the usual Lucas voltage control/cutout used on Morris Minors (a Lucas RB106 model IIRC) there are no fuses in the unit itself. Although it's likely the dynamo has been converted to two brush operation, it's quite simple to wire the RB106 to operate as a cutout only if the dynamo is still three brush.
