We woke up at about 5:30am to an odd sound. At first, it sounded like a water drip, but upon closer inspection it was actually a clicking noise coming from our electrical converter under the seat.
As in Mexico, many of the campgrounds in Morocco don't have enough supply of electricity. So normally, the problem is low voltage. And I'm aware of the problem enough that I bought an electrical meter before coming here and I test the voltage when we arrive at a campground, and regularly throughout our stay.
