This seems like a classic “floating metal” problem. If I am correct, this is what is happening.
The electrostatic build up can’t run through plastic bearings on your lift. These means that the lift and the rest of your system can have different charge. Eventually, the difference becomes so great that the you have an ESD (electrostatic discharge). This fries the out the brain port.
My team had this issue in tower takeover with our lift. To fix this, our team ran a guide wire between our lift and our chassis. We never blew out brain ports after that.
Let me know if you have any questions. Hope this helps!
