My EPS unit (PB82-81B) from NICHIYU FBT 15 forklift burned out, some m-FET transistors just started failing, and after replacing them, the power steering now isn't working. Does anyone have this unit or know where I can find one? Or how to replair the power steering maybe?

Check all the replaced MOSFETs because 1 bad gate resistor is gonna get you bacl to square one. I guess just verify the 12V or 24V power and signal input from the steering controller too. If there's no input, then there's no assist. EPS repair shops specializing in Nichiyu electrics might rebuild it for less than the new! So you might wanna find one where you're at.
