I have a headlight modulator on my Gold Wing motorcycle ( 12V ). When it is actively switching ( 240 cycles per min ) mfr confirms that it causes "power surges". I suspect that the resulting voltage fluctuation is the cause of an associated clicking noise in the audio system.
I believe I need to install a capacitor in close proximity to the modulator to effect a "transient load decoupling" from the rest of the bike's electronics. The headlights are two 45 W bulbs on a 10A circuit.
If I'm off track, I'd appreciate general guidance.
If I'm on track, how do I decide what size ( farad ) or type of capacitor to use?
