It remains to paint and glue the mat.

After assembly, check the insulation resistance on the motor phase wires. We seem to have some kind of wire breaking through! The tightness was checked, everything is dry!
Yes! A little! We’ll figure it out. Punches the phase wire onto the aluminum box.
It turned out that the controller case is like the aluminum box case, which is a minus of our battery. There is no short circuit between the phase wires and the mast. So why was I electrocuted? Any ideas?
It can’t be! It’s been a long time since I’ve been struck by lightning!
Check if the thermal pad of the FETS are still insulated. Maybe the FETS touch the aluminium case.
How can I check it? In this version, you need to disassemble the entire vesc!
If the FETS short-circuits on the case, which is a minus, won’t it burn out?
I’m not sure about it.
Problem found! The sharp edge of the mast clamp broke the insulation of the wire. We need to redo it.
