*Another causes might be a damaged power stage or regenerative drive (some transistors short circuited) of drive, which also would load HV DC bus continuously. To identify if this has happened, see [[Determining Argon hardware failure]]. | *Another causes might be a damaged power stage or regenerative drive (some transistors short circuited) of drive, which also would load HV DC bus continuously.

− | Drive firmware disables power stage and regenerative resistor drive always when RL2 is open, but it can't prevent resistor burn in case of the conditions mentioned above. | + | Drive firmware does disables power stage and regenerative resistor drive always when RL2 is open, but it can't prevent resistor burn in case of the conditions mentioned above. |

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.
