What happens when water gets inside a segway?

Having fixed Segway’s this is just to show what damage water has on the internal components.

Water drips down onto one of the CU boards, as we all know water conducts electricity, 72 volts passing over then shorts out and sets off different error codes.

Even though the main Chips and resistors/ fuse/ capacitors are protected by a glue resin, water will sit at to lowest point can cause a short.

Ultrasonic cleaning the board is then necessary and the applying new resin, then 24 hour stress testing after new solder has been flowing and heat treated.
