Simple problem:
I like analog ammeters. I have one between the panels and the charger. Nice to look at, gives you nice to read information.
I have one between the windmill and the (separate) charger. Absolute bliss to look at - when you have wind :·)
I have one for 24V loads... er well. Just some of them.
Thing is, you know, if I put it between the batteries and... anything else, as soon as the panels are charging, it reads... backwards.
I had the bright :·/ idea of putting a little diode on the ammeter. It's a shunt ammeter, which reads millivolts. Diode drops half a volt. Oh well :·)
Now, I found an old 65A 100V diode in a box.
I put that between the batteries and the load ammeter, it would only show current going one way, right?
OK, I get a (just less then) half a volt drop, I just put a heat sink on it, I don't draw much... before I dismantle and try, what is wrong with the idea/escapes my reasoning?
