I will start by linking back to an older post that I started for a problem I had with a meter display getting that to work. The first post explains the whole thing that I was trying to do.

Everything is working in the circuit for a while. The 2.5K pot that I have in there has been working fine, able to control the voltage for the variable circuit. When I do use the power supply I do not keep the unit plugged in for a long time (average time is around 10 minutes) while I am using it but somehow my pot died on me. If I take my multimeter and connect it to one of the outside contacts and the other prob to the middle I get either 0 ohms or ~2.5K ohms on my meter, even if I move the knob. Any idea on why the pot would just go? I didn't move any wires around to cause a short and was just using the meter yesterday. Do I need to upgrade to a higher wattage pot; currently I have a 1/2W pot in there.
