====== Check cable ======

When suspecting damages to a cable it needs to be checked thoroughly. The possible electrical damage can be divided in two categories: short-circuits and broken circuits.

  * Run the function from the [[:user_manuals:screens#manual_screen|Manual screen ]]with detailed view active. If it is a motor check that it moves, the pulse count and any zero position sensor. Checking the current consumption can also be valuable.
  * Visible inspection
      * Check for damages by rodents or other animals. This can lead both to short circuits and circuit breaks.
      * Check for wear
      * Check for indications of the cable having been caught on something. A cable that has been caught can have become disconnected internally.
  * Measure with a multimeter set to continuity (beep) mode
      * Use the [[user_manuals:electrical_drawings|electrical drawings ]]to make sure that each individual wire has connection between both ends
      * Do cross measurements between the individual wires in a cable to find short-circuits


===== Check connector =====

Always check any connectors on the cable too. Disconnect the connector and check for signs of water, dirt and corrosion. Clean it and dry it and spray it with 5-56 or WD-40.
