As for the volt meter, I suspected a $3 device would not give "accurate capacity readings" (note my quotation marks on original post😅
, but it gives some data as for percentage and voltage output, doesn't it? Should I not trust them either?
Many thanks for the technical explanation and Merry Xmas. 🤝

If you have the original heavy cable to the chassis and the additional ground to the block that James suggests, I think you are good. The alternator is bonded to the block, so your additional ground to the block takes care of that.
That cheapy meter is probably accurate as to it's voltage reading - my point was just that a voltage reading is not going to indicate capacity.
I have a calibrated, lab quality meter we use in the lab. My two plugin voltmeters and my cheap multimeter from Lowes all read within .2 volt of the lab meter.
With today's precision components being SO cheap, it's not hard for them to build an accurate voltmeter.
