What a loose connection will do


This is the breaker on my e-bike. Apparently I had a loose connection which caused arcing when I went over bumps. The breaker tripped a couple times while driving, and when I went to reset it, I realized that the wire and breaker were far too hot.

In the photo, I have pulled the connection out to show the melted insulation. The breaker is charred in places too. Luckily, the breaker is still functional, none of the circuitry is damaged and there isn’t much damage to the wiring. I cut back the wire and there was enough slack to tin a new connection and wire it back up.
