The rear light has stopped working on my '14 Trekking RS. It's the one with built-in generator and Trelock front and rear lights.
I was trying to figure out the right-hand thumb switch, and I wonder if I inadvertently turned off the taillight. The front light works. I've found holding the center button for a few seconds turns the front light on and off. But what do the up and down arrows do? Does one or the other control the front and back lights separately? Do I need to hold them down for a few seconds? They don't seem to do anything.
Does the generator need to be generating for the switch to work?
I checked and with the front wheel turning, I found no voltage at the back light. If not the switch, then I need to check the wiring...
Also, there's the light switch on the Bosch Intuvia display. Does that do anything?
