The biggest problem with any old vehicle is its antiquated electrical system. Ask most owners and they'll tell you the same story. It's a lovely old car/bike but let down by bad charging.

Dim lights?  Bulbs keep blowing?  Bad starting?   Sticking cutout?   Ammeter showing a discharge at speed?   Ignition light glowing?   Dynamo won't charge?   Dynamo over charging? Battery always low? Always have to carry a spare charged battery? 

We specialise in dynamo rebuilding, curing age old charging problems and greatly improving veteran, vintage and classic dynamo (generator) charging systems whilst keeping all components looking as original.

So, if your vehicle suffers from any of the above problems and has a 

three brush dynamo with a mechanical cutout and a fixed charge rate or summer/winter switch or has a 

two brush dynamo with a mechanical regulator or has a 12v Dynastarter, we can cure your charging problems.

All our work is guaranteed


Remember, vintage and classic dynamos, regulators and cut outs is what we do so we know what we are talking about. After a CDRC rebuild or conversion your dynamo and its cutout or regulator box will still look the same from the outside. The only things that change are the performance and reliability of your charging system.... no matter how old it is.


Here's what some of our many very satisfied customers say about the conversion we did for them

1925 Alvis 12/50 Ducksback

"I have now installed your regulator conversion along with the dynamo which you converted from 3 to 2 brush. I am delighted with the new set up. 

The installation was easy with your clear instructions and took no time at all.  When the engine was started the dynamo went into instant charge at just over 8 amps on my ammeter with the charge rate dropping after running when the battery was up to full charge.  It performed just as it should.  With the lights on the dynamo counters the load with the ammeter at around zero. Thank you very much for your help".

1935 Riley Imp 9hp

"After fitting your 3 to 2 brush converted dynamo along with the converted regulator I got an immediate healthy 8 amp charge showing on the ammeter. With full electrical load applied the dynamo is easily matching demand at just 1300rpm with a steady charge showing above that speed. 
The fact that you can email or phone Peter and get a near instant reply or 
friendly advice is invaluable too. I wouldn't hesitate in recommending these conversions, they are excellent."
