I have a '56 model 50, which runs, but produces no power for lights etc.
I think I have got the hang of testing the dynamo, but can't find anywhere a simple explanation of how the cvc works, if the points need adjusting, or how you can test it. I know that there is a modern replacement, but just because its there I would like to see it working. Thanks.
Ps. The horn and lights do work badly, from the battery .
Orriginal workshop manuals …

Most instructions...
... suggest testing with the CVC in situ and revving the engine to check cut-in and cut-out. This seemed a bit barbaric to me so I invested in a variable voltage device - a tenner or so from ebay. I could then adjust the cutout and regulation with the CVC on the bench - much easier and more accurate.

Variable voltage device-
- or in the case an older brother who, upon taking the 8-track player(!) out of his 105E Anglia to provide a sound system for his room, hooked it up to his old Hornby-Dublo mains transformer for a 12v supply.
Worked fine- but boy the background hum from the mains!

Horn and lights working badly
A static battery and one fully on charge should mean a difference of 1.2V max over the 6V. So it might be best to start getting the 6V at the battery to the lights and horn first.
By the way Mick, the answer would have been the 2MC (or equivalent) across the DC from the Hornby Dublo-sorted.

Thanks folks.
So it seems to be working now, whether its correct or not remains to be seen,thanks for your input.

Orriginal workshop manuals from the 1950's sometimes contained a detailed description of how to set up points and test the various types of CVC units . Just keep looking.
