(Hey all! First time making a thread, so feel free to tell me if I need to change anything!)
I made an electronic skateboard last year and it was working great until a few months ago. All of a sudden, whenever I hit a bump in the road, the power temporarily cuts out (and usually comes back on in a few seconds- but by that point I have been knocked off the board). I thought it was just a loose wire initially, but I’ve re-secured all connections and the power cut-offs are still happening. Now I think there may be something wrong with one of the connections between the VESC and the motor. When I move one (the middle) of those 3 connections when the board is on, sometimes sparks shoot from that connection and the motor halts, even though the wires are still connected. Is there a reason for this, and is there a way to fix this?
(I have a video showing the problem, but I am not sure how to post it yet. I will try to get that up tonight if it helps)
