Gurus,
I said that in the earlier post that the bottom 120V input to the board (the one that did not burn up) was loose. Here is an image of one of the solder joints on that connector.
Do you see any issue? (Just kidding). It is obvious that this was a cold solder joint.
My question is…. WHY?
This looks like a mechanical break to me. Like something was flexing the joint until it broke. The wires where neatly arranged in the junction box and I cannot imagine that road vibration did this. I am stumped.
Cheers,
Bill
