Fortunately for me a new battery to motor cable resolved the issue. Shimano even covered the cost of the cable. My LBS mechanic stated that if failure were to occur again that Shimano would warranty the motor and power cable. I hope it doesn’t happen again and I have already done the dielectric...
Glad to be here. I have a Canyon Spectral ON. I have encountered a couple of electrical glitches. Hope to find some direction with this group. Thanks everyone.
