I frayed a power cable that connects from the ESC to my right motor during a ride (DiY battery pack, too large, physically pushed the cable into a circuit board edge during a test ride). Upon troubleshooting the issue, I found that the motor that worked during the test ride is now hardly performing. The motor is no longer rotating; it just twitches slightly. When connecting to the non-damaged esc power cable, the motor works. Would anyone happen to know what the cause/solution may be?
I tried to splice & solder the frayed wire together, but the issue is still occurring. Am I screwed? Do I need to buy a replacement ESC?
