Ferrites, and buzzing
Hoping to start a discussion, not solve any issue here. I have a "watt's up" wattmeter clone from Windy Nation. This came with 8awg leads instead of the usual 12awg. I'd found its AH and KWH fi...

Ignorance is such bliss.
While not learning anything, i was happy that the schumacher would seek and hold a respectable absorption voltage for almost not quite long enough on the AGM setting to actually get the battery close to full charge. It floats at 13.6, so eventually....
Now I had to go and experiment with wattmeters and ferrites and found all is not just a 'super groovy just fine'.
I wish I had the time and gumption to get the ferrite to not buzz.
But the battery charges. it is simply the one wattmeter does not like it. I have another one which does not care.
The problem only became apparent when I tried to get the unhappy wattmeter to be happy.
But is it really a problem?
Hmmm.
So say I have various cheapowatt recycled capacitors I was willing to put on the output terminals to see if I could eliminate the ferrite buzz, and perhaps get screwy wattmeter to not jump around whack a doodle like. How do I go about finding which capacitor leads go on the + or -?
I get that new capacitors are cheap, but, I am not buying anything I do not absolutely need to at this point, and this does not even come close to that threshold.
