John and all others who have responded to my thread re the ''dynamo''. I have found the problem. The engine on the car has always been reluctant to start as the cranking speed was just not sufficient. Either the oil is too thick or the starter is old and just not able to crank at a normal speed. My solution was to fit another 6 volt battery in parallel with the existing battery (i.e. increasing the size of the 6 volt battery). This certainly helped the speed of cranking and hence starting. Giving the same voltage but greater amperage. I had thought this a good idea. However having established that the dynamo is giving out a good charge and checking the wiring from the cutout I was still not able to get the charging light to go out. For some reason it occurred to me that maybe the second battery was causing the problem. I disconnected the second battery and hey presto the ammeter showed a charge and the charging lamp went out. There will no doubt be a technical reason for this which I haven't yet been able to work out no doubt involving advanced electronics but all is now working normally. There was probably nothing wrong with the dynamo in the first place. Thanks for the help though.
