You should have no difficulty in running a C35M dynamo with a CF1 cutout. MY RP saloon has exactly this arrangement. My switch is (of course) not the same pattern as yours, but it should work in the same way:- On winter charge, it connects the dynamo D and F wires together. On Summer charge, it disconnects them and allows the field current to run to the D terminal via an approximately 2 ohm resistor which is wired permanently between the two terminals. On the C35A instrument, this resistor lived with the field fuse under a cover on top of the dynamo itself. What I have done is to interpose a power resistor between the D and F terminals on the back of the switch and hide the resistor itself under the dash.
I hope this helps, but it is beginning to to sound as if you have two problems:- a dodgy cutout and a problem with the switch.
