Even without voltmeter abilities,
"Auto Zone" and "Advance Auto" both have a little meter that has LED lights on it (I even "had" one, for my wife's rig, I was gonna snap a pic and post it, however, she just told me she lent it to one of her employees, months ago.I reckon I need to go shopping. They're not but a few bucks!
The way you use it is Vehicle OFF touch it to the battery terminals and it will indicate whether your battery is Charged or not. Red or green light
Then you crank it and touch the terminals, it will display your alternator output, red, yellow or green as far as how well it is charging.
Probably a decent investment at less than $10
It was gray in color and maybe 1" X 1-1/2" X 4". With 2 short leads, and 5 or 6 LEDs on the front
Sorta primitive, but some people need something compact/ durable/ fool proof/ and also "doubles" as a useful gift for an employee!
