Tough problem with all the ICs soldered in.

Chances are that the 32 volt supply is only used for the L298s, as you
suggest. It also appears that you can unsolder these without damaging
any other parts on the board. (Even if you have to cut them out,
they're still available and easy to replace.)

If your short doesn't disappear after pulling the 298s, try
unsoldering any of the caps near those chips.

Leave unsoldering any ICs as your very last resort.

I'm now bowing out of this discussion and leaving it to the experts.

Good luck, Robb.
