Electric Wheelchair Controller

My friend came to me with a simple request. To repair his electric wheelchair after it was damaged by lighning while on charge. The chair was fitted with a Shark controller, and on opening, there were severe flash-overs visible on the controller PC board. Being made of just surface mount components, it was clear that the Shark unit was beyond economical repairs. After trying to get support in South Africa, and many hours of Googling, the cheapest solution was to import the complete controller, harness, and joystick unit. But total cost would have been around ZAR10 000. Money my friend does not have.”
