Hi, Im new here and know very little about electronics, my problem/questions is:
I have a 1944 HD WLA Motorcycle that runs on a 6v system. The generator is switched by a simple mechanical relay, no voltage regulator, the generator at idle puts out 6.4 - 6.8v as per manual, the problem start when rpm is increased, the voltage spikes to 8.1v, needles to say I go through a few 6v bulbs (35w). See attached extracts from the original manual on amps. On the wiring diagram you will see a condenser on the generator, this acts as a radio suppressor, I would like to replace this with a modern capacitor to smooth out the spikes in voltage.
Will this work and how do I calculate the size of Capacitor required?
Many thanks
James
