> I use inexpensive (now discontinued) Radio Shack bench volt and

> bought mine for around $9 on eBay).
>
> In a "senior moment" (cough) I recently mistakingly hooked 12v from a
> small 0.8ah gelcell battery (that I connect to my KX1) directly across
> the + and - terminals of my 0-1000mA meter. After the smoke cleared,
> and I disassembled the case, I noticed that I had melted a wire
> connecting the meter to a binding post.

> The ammeter is a simple meter with three binding posts... 0-500,
> 0-1000 and common. It sold for around $13 at Radio Shack (part number
> 22-401) but was discontinued over a year ago (I've tried to just buy
> another one with no luck). Inside the small plastic case is the meter
> and wires, no other parts.
>
> Internally, the meter has no part markings other than the word
> "CHINA". The black (hookup) wire from the meter terminal was soldered
> to a bare wire covered with loose fabric insulation, which was then
> soldered to the common (black) binding post (this was the wire that
> melted), and the red (hookup) wire connects to a bare wire which
> connects the (red) 0-500 and (red) 0-1000 binding posts and is covered
> with loose fabric insulation close to the 0-500 binding post (the red
> side is still there and did not melt).
