I have aquired 3 of the Leadshine AC806 drives with 400 watt motors new in the box (from a customer who wanted to trade parts), and was setting them up on a customers router retrofit. The first 2 drives powered fine, but the 3rd smoked as soon as i turned it on. I'm just running 48 volt dc and the motor cables weren't connected,

I took the lid off and saw a surface mount diode cracked. I checked all the mosfets (just IRF540's) and they all test fine. I replaced the diode, but it doesn't light up.

Anyone else have experience with these drives ? I'm not sure about the quality control of the drives, but the motors are really nice.
