Hi Nick
I'm just wondering if you have the type of ammeter with terminals, or the type that has a turn or two of cable clamped to the back. If it's the latter type, then too many turns will produce more magnetic field for a given current, and thereby make it over-sensitive. Sorry. I can't remember how many turns it should be.
