Wow Doug!
The Electrode is the load to the circuit and can easily cause a fuse to blow. I NEVER said there was a short. You did.
I have worked in electronics for 35 years. I do not confess to being an expert but I have seen some odd issues that could not be completely explained without the proper testing equipment. This was one of those. It was a "Best Guess". Except the fact that it is working. The control module may have an under lying issue but until it goes out completely I will except what I have. You should too and quit being so negative.
