I have a situation where an EMF induced voltage from the ignition coils is causing issues with a new electronic flasher relay on a vintage motorcycle (12V system) and was wondering what the most effective way is to eliminate these spikes. The control line to the flasher relay is picking up the EMF and appears in the neighborhood of a couple hundred volts at the ignition frequency – the spikes are very narrow but I don’t have an actual measurement. I have tried installing a .1 uf ceramic 100v capacitor to the flasher control line and it eliminates the noise. So the question would be would this be acceptable protocol, and if so how would the voltage rating for the capacitor be determined?
Thanks in advance for any response.
