Deborah's father came to fix the cart. As he predicted, he found the main cause of the cart's troubles within minutes, and then spent the next few days remedying other, more minor flaws.
When we went over the big bump, the reverse relay had closed at the same time the forward relay was operating... which shorted out the batteries in a hurry. The relay was unwelded with a tap of a hammer. When I asked what we could do to prevent this from happening again, he said, "Slow down when you're going over bumps." Oh. I had been hoping for something more along the lines of suspension...
The steering as getting loose, too, so we jacked up the front end and tightened the bolts that carried the front wheels. This probably has something to do with my belief that four-wheeled vehicles really don't need to slow down to take a turn.
Cart and creator, ready to roll again!
