Dave,
Here are the results of dynamo voltages. First test followed by second test:-
1929 chummy 4 field coil dynamo 0.24v and 12v. C35A with C35M brush gear 0.1v and 8v.
C35M 0.9v and 12v. C35A 0.1v and 8v. C35M 1v and 7.9v. C35M 0.4v and 8v.
As Adrian says these dynamos needed a good few mins running before the field coils would function.
They had been in the cupboard for many years.
All 6 dynamos work as motors.
