Hi I've just bought a pre owned fat bike, not sure of the exact model but it has the "Wendy" led controller.
I inverted the bike to swap brake pads (being careful not to damage the controller) but it began to rain very heavily so I left it in situ and when I came back to the bike after a day or so I couldn't start it, yes the battery was charged?
The screen was completely blank, no led's on the throttle.
then after 24hours the lcd screen showed the 'boxes' where the information should be but just the boxes no actual information, this screen is visible even with the battery removed, so I'm thinking rain penetrated the lcd controller whilst the bike was inverted.
Ive now opened the controller and left it indoors in the hope that it will dry, and will put it in a bag of rice to absorb any moisture from the circuit board, is there anything else I should try?
