I have ordered an electronic regulator for my Lucas DEL but understand that these need 2.5-3.5ohms resistance in the field coil to work correctly. Mine only has 2.1ohms which I believe is pretty normal. Can anyone explain what the reason for this requirement, and whether the problem could be resolved easily by say adding an extra resistor into the circuit or is there a fundamental issue which would require a more drastic approach- rewinding I assume? . The dynamo has been rebuilt at least once so the windings are good and I don’t want to have to do it all over again if I don’t have to. I have earthed the third brush to allow it to operate as a two brush unit.
