Reply to "Short in engine with ERR Cruise Control."

Without actually checking what component is shorted, it's hard to say if it's repairable.  It's most likely the bridge rectifier or one or more of the motor driver FETs, (TO-220 parts bolted to the heatsink).  I believe those are the only parts that could actually give you a total short indication.  My experience has been it's more often the FETs than the bridge rectifier.
