Two Triple AAA batteries in Toilet Waste Compartment

[Chrisgr31]

As the thread title says there are 2 triple A batteries in a holder adjacent to the toilet waste container in my caravan. They are connected by 2 core cable to something, but I have no idea what! Anyone got any suggestions?

Thanks for all your helpful comments! Will search for a light that indicates toilet is full!
