On 5/6/08, loopcycle put forth:
think it matters, although every diagram I've seen has shown the red
meter lead connected to the negative side of the circuit (ground or
the negative supply). Which looks backwards to me. My digital meter
will show either show a negative sign or not depending on which way I
put the leads, or which way the current is flowing, depending on how
you want to look at it.
