Yes, it looks like the triangle wave superimposed is 13V p-p .... I think .... I'm still realizing how rusty I am with an oscilloscope.
Approximately how may amps should the control board be using?
The Cincon is putting out the correct +12V ... I was trying to find it with reference to the digital ground, not the power board ground ... the gate signal is not there at all, just the triangle wave stuff.
Thanks so much for your input and ideas.
