I was having issues with my Bosch system, the batteries were fully charged but the Purion display on my Gen 2 GSD S10 wasn't turning on, thus not sending a wake up signal to the batteries.
After a firmware reset, and replacing the CR2016 batteries in the display, (and still motor not turning on) I took off this motor housing cover to check connections... and revealed this disgusting cache of debris. This picture really doesn't do it justice.
Full context, I ride year-round in Michigan so I have my share of shitty road conditions. Sometimes slush would accumulate outside the motor but I would always wipe it off. But clearly road grime is finding its way in there.
How often do others who ride in winter conditions clean out the motor housing? Any preventative measures I can take, even DIY hacks? Anything else I'm overlooking on this critical area/potential fail point of the bike? Thanks in advance for any insights!
