There are three connections to a pot, the outer ends are the two ends of the pot connected to power +v and Common, the third is the slider which taps off this 0 to +ve.I don't understand what you mean by "one outer connection".
Not sure I do. It doesn't make sense to me that it would matter which way the current flows through the pot as long as it's flowing through the right connections. I tried it anyway like I said and same result.
There is only one correct way to connect it, there is usually a low voltage supply connected to the outer ends, the slider connection usually goes to a high impedance input of some kind, if you connect the slider to the +v say, and turn the pot to 0v, you are effectively causing high current to flow and end up shorting the supply.
