OK, I actually took it a step further given the low current draw. Now running with just a Cruise M. The bridge was removed from the M and is mounted to the frame. Total motor drive current is between 1 and 1.2 amps. I can afford to blow up this board in the interest of science. Don’t try this at home. Further testing will have to wait until I can get on the club layout and start pulling some serious loads.
