8531 /Burner Issue UPDATE--Photos ( Fixed!)
With the furnace running, where do you put the pos and neg leads of the meter? Or can you do it at the Tstat inside with the furnace on? I want the 12v to the board, not the voltages the board puts...

If you hear the click,that is the spark going somewhere. Possibly damaged the big wire, or cracked the porcelain. When you pull it out to test it, the burner housing must be touching another metal part of the furnace,or a jumper wire used, to have a ground.If mot, the spark can jump down at the control board.
The snap switch is the high limit safety switch, they are model different.
PS The guy in the video is wrong(rare for him,he is good), it is not 12 volts on the big wire, it is several thousand. The igniter system is basically a coil and spark plug.
