There is lots to read as you click through.

Click HERE for instructions on how to do a simple test to see if your dynamo has a healthy output.

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, dynamos, regulators and cut outs is all 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."

Feedback from one of our many satisfied customers about our LED Double Dipper dipping headlamp bulbs

Peter has obviously put a lot of time, effort, money and passion into his products, I have a converted a 1936 Alta to total LED with fantastic results in light output and minimal amp draw  

(I left the lights on for 24hrs and was still able to start the car easily!) I have followed the development of the new 'double dippers', pestering Peter over the months but he rightfully would not release them until he was happy. They were worth the wait, a very high quality item, fitted and used first time on the Mille Miglia 2015, lights on for the whole 4 days, a fantastic spread of light on dip beam, comparable to modern vehicles with upgraded halogen/Xenon bulbs. Add to this the relatively low cost for such a product and reliability plus minimal consumption…. why use anything else?? I won't be from now on. Congratulations Peter!
