Yamaha 2400 generator's on-board 12V charger
Not related to charging my TT batteries, but a question about the on-board 12V charging system in my Yamaha 2400 inverter generator. The other weekend I needed to fire up my new-to-me riding lawnmowe...

You must accept that the built-in charger is merely a nice to have feature. You 'can' recharge a 12V battery with it. It will supply up to 8 Amps.
That said, here's what we're dealing with:
Without connecting the cables to a battery, there's some AC ripple on the waveform - should be flat:
Before starting, the voltage on my battery was 12.64V. Upon connecting it to the charger...
Please understand this is not unusual for a cheap grade charger. The voltage is not well regulated, but the current is limited, which prevents boiling an automotive battery.
I have used this setup many times to put a charge on our boat that was in storage (no power there):
Almost any standalone external battery chargers connected to this generator will outperform the built-in charger... but it does work!
