      • The two new capacitors are in place.

      • WARNING: if during reassembly, the capsule goes into a "high temperature" alarm on Airport, with the fan running and the orange light flashing, this is probably due to contact between the "-" leg of the lower capacitor and the wire below.

      • To avoid the above problem, you have to put the small silicone tube removed from the old capacitor back, and don't hesitate to put a bit of nail polish to hold it together.
