Automotive Dynamos and Starter motors in there simplest form are straightforward electro-mechanical machines, but most have their own quirks and shortcomings. Over time, they develop any number of defects which require attention. These include seized or worn out brushes, worn out bearings and bushes, broken down insulators and sleaving, scored commutators, heat damaged armatures and defective field windings.
Our services include:- testing, repairs, complete overhauls, 2 brush dynamo conversions ( converting from "Cut-out" to "Regulator control"), and Concours restorations are also available if required.
We work on many  types of period units from the Edwardian era to the Sixties, these include:  C.a.v, Lucas, Bosch, Marshall, Magneti Marelli, Delco, Ducellier, Rolls Royce, Simms and Scintilla (including Basculating starters) as fitted to Bugatti's and other prewar cars.
