Well there are 16 corresponding coils on a stator type plate. So as the flywheel spins, the magnets induce current in those coils to power the trembler coils. It is a very old school type assembly and quite heavy. The timing is done with a small distributor type timer on the front of the engine and you have to adjust it as you drive. The strange thing is that there is a separate generator (on starter motor equipped cars) to recharge the battery. A lot of people take out the whole magneto assembly and just run a period small magneto or an almost period distributor. It is a lot easier to do that, but I wanted to keep the authentic set up, even though the car is not that authentic. It is quite fiddly to set up as the plate and flywheel has to have about 25 thou gap. Too larger gap and the magneto does not work well, too smaller a gap and flywheel will hit the coils and make a real mess. Now if I just have a bit of luck, I am only about a month from getting her on the road ( I seem to have been saying that for a year now).
