Battery charge/discharge indicator?
I'm pretty sure the ammeter in my old 1990 Winnebago Warrior is shot. It doesn't move and the needle stays slightly to the charge side. I would like to add a display to my dashboard that has two L...

I had actually already seen that article when I was searching.
What it appears to do is give you a visual cue as to the state of voltage of the battery. But it does not tell you if it is charging or discharging.
You could have high voltage and still be discharging, for example.
What I'm really after is a "optical" ammeter that glows green when current goes one way and glows red when current goes the other way.
I'm surprised someone doesn't manufacture a dongle that you just put between your battery post and the terminal that normally connects to it, and this magic device has low-voltage leads that go to a bi-color LED display located remotely from the battery.
The problem with an actual ammeter is you have to wire it to handle all accessory load for the entire possible current that might be going through your system. That means heavy-gage (14 or thicker) wire going to wherever the ammeter is located.
