I would call Dinosaur direct and ask them for help. Jim K. Is great for warranting things but in this case Dinosaur tech support ought to get involved. 4 or 5 years ago George Z. had a similar type of problem and Dinosaur built him a modified board to take care of his issue.
The problem with my trying to trouble shoot their board is that we do not have a diagram of their board, so all we can do is check inputs and outputs which are identical to an OEM Onan board. Anything internal to the board is a different issue.
My first guess is a over draw by something on the Onan, but there is a 5 amp fuse on the board that should blow in the case of an external to the board short somewhere. I assume that you have checked that fuse.
Keep in mind that the same circuit feeds the fuel pump, fuel solenoid, and ignition ignition. The single fuse feeds all of that plus the choke.
I'm sorry I'm not much more help but my Dinosaur board experience has only been that you install one and the generator runs. I have never had to de-bug or trouble shoot a defective one.
