Duane, one arc and the whole control board can be zapped.
I fixied my own control board on my Centaur, but I had replace
just about every transistor and diode. I assume the Centurion
has a control board also. I called Ten Tec and they were very
helpful. They wanted me to send it back so they could do a
complete job. I would rather fix it myself and learn something.
