Problem description

Joycons not charging or connecting/pairing. Joycons aren't charging (on one or both sides), the fan works, and the side-rail is confirmed working.

Symptoms

  • Joycons not charging or connecting/pairing
  • Joycons aren't charging (on one or both sides)
  • The fan works
  • The side-rail is confirmed working.

Solution

Diagram showing resistor layout

Measure both resistors. 18kohm on both resistors indicates a failed/shorted capacitor (even if the cap does not test as a short). Resistors should measure 100kohm and 22kohm respectively. Measure pin 6 in diode mode-- it should read 0. If it reads 0.6v drop this reinforces the capacitor failure.



If resistors check out, the DC-DC component may need replacing
