Hello,
Am testing a POT on a breadboard and after turning it on approximately 20secs later a tell-tale burning smell occurs. The setup is easy enough: breadboard powered by single Voltage source (14v), and the variable resistor. When I set the wiper to maximum I get 7 Volts signal out; when I have wiper set to minimum the output is 14 volts.
If I am facing the POT - the left lead goes to hot; the middle a wire setup for probing by voltmeter and the right to ground. Is this setup correct? Obviously something is getting scorched.
