Comunque credo abbiate ragione tutti e due, nel senso che:

 

Thats the best answer. The ballast reduces the current flow thru the coil at low speeds and keeps the coil from overheating. As was said the coil can handle more amperage but not for long periods of time. So at idle and low eng speeds the points have more time to be closed and thus the current heats the ballast up and causes it to have more resistance and drop current flow at lower eng speeds when full coil output is not needed. When you go faster and speed the eng up the points have less time to be closed so the ballast cools down some and the resistance drops causes more current to flow thru the coil and letting the coil output higher when it is needed at higher eng speeds. And when cranking the ign system needs full output to help start the eng so the ign switch bypases the ballast and gives full battery volts to the coil while cranking. Ron

è una interazione tra resistenza, temperatura e voltaggio. In effetti la lampadina spia era fioca (8V o simili) a quadro inserito, brillante all'avviamento, e accesa normale al minimo, accelerando aumentava la luce... Resistor che si scaldava dopo qualche minuto...  :ok:

 

@Er, hai ragione solo che adesso sono tornato a Cuneo, dopodomani mi arriva il condensatore nuovo e sabato prossimo riprovo... tanto quando esco io dall'ufficio i ricambisti sono tutti chiusi  :frown2:
