What ever happened with yours?
Did you get a replacement display, and if so, did you get it from RPB or from a third party?

Sorry for late reply, only logged in to do some searching on a unrelated project.

Friend purchased a new LCD from the RAD website and it works perfectly. As far as where
I got the pinouts....I cant remember honestly. I scoured the webs for days and finally
found it somewhere.

A friends RADRunner had been carried on a bike rack through several rains. She says there was moisture
visible inside the LCD display. The bike would not turn on, so she left it with me to troubleshoot best I could.

Through much searching, I've determined the harness female pinout is as follows:
-
Pin 1 = Power + 48vdc
Pin 2 = Ground
Pin 3 = Transmit Data
Pin 4 = Receive Data
Pin 5 = Power Lock

Measuring voltage between pins 1 and 2, I do see 53vdc. When MODE button is pressed the
LCD comes on and looks like the attached picture, then goes off when MODE button is
released.

Everything points to LCD needs to be replaced: https://radpowerbikes.pxf.io/zNEbyG

Just a sanity check, agree to replace LCD?  Or is there a chance the Controller needs replaced as well?
