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.
