A friend bought a KBIC-120 controller to use with a treadmill motor on his lathe. He hooked it up per the manual, but it blows the AC fuse immediatly at turn on. Loud pop. I have the controller on my bench. I have checked his hook up and it was correct. He has the correct fuse, and correct power resistor for 1 hp motor. motor is a PM type.
Anyone have experience troubleshooting KBIC SCR controllers? Help! at this point, with all connections removed except the ac in and the fuse, it still blows fuses. Help please!
