    A rough guess would be that the alternator possibly has lost one of its high current diodes.

    Subject: Noisy voltmeter
    From: "Achille" <mickael.t@live.fr>
    Hi all, I have a question about a problem that i have with my new electrical system. I have a two way switch with 2 voltmeters, one for the main battery and the other one for the aux, still hot battery. When I set this switch on, i have a noise in my headset. And it's the voltmeter one. I wired all my electrical system with the one point ground bus to avoid this kind of problem. I set the noisy voltmeter on the ESS BUS, that is after the diode (my diode is set between the main bus and the ESS BUS. (I wired the Z19 diagram from bob electrical system) Do you have any advice ? (this week I will try to disconect it from ESS BUS and try on the main bus in a first time.) thank you in advance ;) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=485847#485847

    Here is the update on my Plane Power alternator. It was tested at PP and fa iled internally not related to the voltage regulator. A new replacement will arrive tomorrow under warranty. Thank all of you for your ideas and help during this process when the altern ator still operated but kept tripping the field, but would reset and operate normally.

    Subject: EarthX Battery Tester
    https://earthxbatteries.com/shop/optimate-lithium-battery-charger-lifepo4 The chargers EarthX sell will wait 30 minutes after charging and then check the voltage to see if the voltage has been retained. If it passes, it will wait up to 12 hours and then check again to check for excessive self discharge. Is this sufficient to confirm that the battery is healthy or would some sort of load test also be a good idea?
