Hi All,
Hope this is not straying off topic too much. And I apologise if this specific question has been answered elsewhere.
I have just fitted a C35M dynamo, assembled from a bag of bits, new brushes with turned down and hacksawed commutator. I've got a cutout from a 1937 A7.
The minimum charge on the ammeter is 8amps. Summer setting and third brush pushed to the top. As I've got new brushes, I'm concerned that this might get even higher, as they bed in. I would like to run with 1 or 2 amps on Summer, and maybe up to 8 amps on Winter. Any ideas what I have done wrong?
My previous dynamo, had just enough charge to make sure the red light went out. Adjustment of the third brush sent the charge rate directly from very small to 14 amps, as shown on the ammeter. Battery always seemed to have enough oomph in it, but felt I wanted to try a different dynamo.
Finally - what happens when the wires on the dynamo are fitted the wrong way round?
Appreciate any help you can give. Not too worried, but got Nightjar rally tomorrow, so about 5 hours of night running.
Regards,
Colin
