Reply To: Dynamo not charging battery. 1955 11BL

Hi,

It’s good to see others having the same problem as I have, though in my case the cause is fairly evident, it’s the solution that is the problem.

I was getting a mechanical buzzing from behind the instrument cluster at high revs and the ammeter showing discharge. I disconnected and bypassed the ammeter, and discovered the noise was coming from the regulator on the bulkhead behind. The contacts were furiously buzzing open and closed, and now do it even at low revs.

As I imagine the regulator is a lost cause, my next move appears to be to replace it, but I have a 6v Ducellier system and 6v Ducellier 8259 regulators are currently not to be found in France, Belgium, the Netherlands or Switzerland. Unless there’s a source I am ignorant of, I imagine all I can do is replace it with an electronic unit. But I’d prefer to keep it original and in-keeping with the rest of the car.

Any thoughts and advice most welcome

Thanks,

Andrew
