I thought about that but discarded it because I thought a break in the wires would yield no reading

My egt reading on my #1 cylinder has been lower than the other three cylinders ever since I had my cylinders done. I noticed that the temps of the other three are running about 1350 while the #1 is running about 1150. Today I installed a new aux. fuel pump. I started the engine (io-360) to check my installation. Because I was at idle on the ground, the temps were running about 940 on #2,#3, and #4. The temp on #1 was 190. My first guess is a bad bayonet probe but I don’t know how to check it. I could just order a new one but they are a bit pricy. The engine runs smooth and the cht reading on that cylinder is right in line. Can anyone tell me how to test it?
