Looking at the other components near these diodes, it's my guess that these are part of a DC to DC converter, maybe to get logic and gate voltage? It looks like there are another set of diodes for the motor bridge FETS on the bottom side of the PCB. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Dive into the World of Parallel Programming.
