Interested in this thread. I had endless trouble with the cut out and then dynamo on my '32 RN so bought a dynamotor stupidly ordering + earth instead of negative earth so had to convert the car electrics. The unit failed after a few hundred miles and the supplier sent me a negative earth unit without charge even though it was well over a year since purchase. This unit then failed a few hundred miles later, bringing the car to a dead halt on a fast road by fusing out the supply to the coil. So I purchased a cut out for £45 and a dynamo at the Moreton show for £75 which predictably didn't work. However the all knowing Andrew Jarmin (Cornwall A7 Club) breathed his magic on it and bingo I have sparks again. Sadly fitting it revealed that the dynamo drive gear and camshaft drive gear are b*ggered adn worn away now so that's another problem to fix. I see the Dynamotor is off the market now, fortunately. Also fitted LED lights bought at the show and the brilliance of the brake and indicator lights is a revelation. A major safety improvement.
