{{Electricshock|Before proceeding with the tests, make sure drive has been safely discharged for at least 15 minutes before opening it. Any remaining voltage in the device may interfere the measurements here. See more info [[Power supply safe discharging|here]].}} | {{Electricshock|Before proceeding with the tests, make sure drive has been safely discharged for at least 15 minutes before opening it.

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.
