Correct, not fried and not working. Almost all of the current going through the ammeter is going through a shunt. A small amount goes through a fine winding between two magnets which will swing the needle either way. That winding could have fried, broken or who knows. The new ammeters really are junk. It's probably just as accurate with the needle at 0 as it was when it was moving.


As far as the bad cutout... yep I've got one too except if failed closed, acted just like your jumper. Was a new in box diode cutout... oh well.
