I have a 12v pwm motor control. The output diode across the load continues to get hot when running. The motor load is 6A, 10V, 5kz pwm. the diode is rated 600v,4A,fast switching.MUR460 is the number. The supply to the board is 13v dc from fwb transformer/rectifier. I thought this diode is just for wheeling. Can anybody give me some areas to troubleshoot?
thanks,
jeff
