Reply to "Amp Gauge waving like a beauty queen in a parade"

maybe I am going to ask some really dumb questions, but remember I am just learning.

I have read the panterplace and done a little googing and my take is that a large part of the problem could be the mechanical voltage regulator. so is i possible the ampmeter is showing the actual output of the alternator. with the simple design of the veglia being responsive to the the voltage regulator cycling and the normal wire wound shut having enough damping not to show actual conditions. I would think if you had a fast resonse anolog voltmeter, you would see the same waving of 12 to >14 VDC.

so has there been any past changes to the regulator to smooth out the field current to the alternator? I would think adding a filtering circuit, or just a capicitor would solve the problem. But being so simple, there must be something else.

Also, a filter on the diode half waves would take out the high freq ripple
