It's me again,(pots smoking) I wired up my amp meter on the return side of my circuit and it works perfectly good. I dont even have to hook-up the second wire of the amp meter, but I tied it to ground anyway. Has anyone ever seen something like this before? I just cant understand why I can't place my amp meter inline and get a current reading with these Chinese meters. Like I said before, if I hook the meter between a circuit it should read the current passing through that line. Instead it keeps buring up my pots I use to vary my load, So I give up, I'll just wire them to work.
