For some reason there was hardly any charge left at all and confusion insured wondering if we were switched to the top battery back or the bottom one. Regardless of what we thought we had to stop and do it quick before we just stopped in the middle of the road. Gordon turned the switch one direction and then the other and discovered the switch was switching too easily. We drove another 100 meters and stopped in front of a cafeteria coffee shop. The owner was not pleased when I asked if we might be able to plug into the socket outside and, no, we couldn’t order any coffee or anything for that matter. He eventually allowed us to plug in while Gordon took the right side panel off to get to the tool kit. There were now a variety of things strewn along the side of the Tapir. Gordon took the switch off and discovered the inside had melted and other parts had simply vanished. Like a proper surgeon he performed a bypass and that solved the problem. It would take more time to switch from one pack to the other but we were now able to keep going! He wrapped it all in tape, the bypass, protecting from getting a shock and besides our hair was curly enough.
