You can check for battery issues by seeing if your phone turns on while plugged in. If your phone does turn on while connected to a power source, you can check the battery health using the following steps: Open the Settings app on your phone. Navigate to the Battery settings tab. Select the Battery Health option from the Battery menu.
Remove the negative battery cable from the negative battery terminal. Find the negative cable, which will be marked with a minus sign (-) and may have a black cover over it. Remove the cover, if applicable, and use a wrench to unbolt the negative cable from the terminal. Be sure to use the negative, not the positive, cable to test for the draw to …

It is between the alternator and bus, while the ammeter is between battery and bus. Your 172 has an ammeter. If it indicates zero in the runup, and you actuate the flaps, it should stay at zero except for that tiny flicker of the needle. If you turn everything on--all the radios, all the lights, and hit the flap switch, it should still read zero.
The path back to the battery is a little more complicated, but there where it says "Battery Feeder", you can see it goes through a 70A fuse, down to where it connects to the battery contactor. So when the alternator switch is on and the battery switch is on (closing the battery contactor), the alternator can charge the battery.
You turn on your headlights and start up the heater fan. Immediately you see the needle momentarily jump to the minus side, then come back to 1-3 amps on the charge side as the regulator manages the generator output to meet the increased demand. ... This lack of sufficient power generation can fully discharge a battery if allowed to go …

I am not sure about "You said the ammeter showed how much the alternator was supplying. No, that is incorrect." It may vary from model to model. If you have a failing battery, the ammeter may show 14 volts or so. That is what the alternator is putting out. You turn off the engine and the voltage indicator may show 10 volts for a battery …

As the title says, the laptop no longer charges when it is powered on and open. It charges fine when in sleep mode, with the lid closed (and powered on) or when turned off, but not when turned on and open. Oddly, the laptop sometimes says it is charging for maybe a second or two when first powered up, but then nothing.
The battery has not been removed and has been in the mower for better than 5 years. This started when I turned the mower off for a bathroom break and when I came back the mower would not start so I jumped it with a battery charger with a quick start mode. While finishing mowing I noticed the Ammeter was reading -8 (Negative).
