Sorry it was on the resistance settings... just meant the 20k resistance setting on the voltmeterAl said "In the new photo I have the 240 installed... removed the pot and checked the resistance between the two pot connectors... I got -7.5 on the 20k voltmeter setting. I am guessing that is 7500? Not sure if the negative symbol means anything"
You can't check resistance on the voltage setting. What brand and model of meter do you have? I might be able to help you with the dial settings
so that you can measure resistance.
