*Drive's internal fuse has blown. To check this [[Argon user guide/Power supply safe discharging|safely discharge drive]], remove cover, remove fuse and measure fuse resistance. If high current & power is demanded from the drive, then a higher amperage fuse may be installed in the place of original. Maximum fuse size is 16A slow blow and the factory default is between 6.3-8 A slow blow. | *Drive's internal fuse has blown.

Measuring condition of B3 is possible with multimeter's diode check function. Check all four diodes from the test points marked in the image. Multimeter red lead goes to anode and black to cathode. All diodes should give reading of 0.4 to 0.5 Volts. | Measuring condition of B3 is possible with multimeter's diode check function. Check all four diodes from the test points marked in the image.
