AA batteries in toilet waste compartment

Hi, new to this forum!
On inspecting recently purchased 2002 Ford Rienza we have found two AA batteries connected to something but are located in the toilet waste compartment.
Does anyone have any idea what these power?

These are designed to power a level system using a reed switch and magnetic float in the cassette. There will be a lamp in the loo to warn you when the cassette is nearly full. (On our manually flushed C200 it's to the right of the flush pump handle).

You will find many people don't bother with this as it is very simple to tell how full the cassette is by simply looking when the flap is open during/after use. It's better not to let the cassette get too full anyway, as it gets quite heavy and cumbersome; best to empty it regularly. I'd also suggest removing the batteries to prevent them leaking and corroding.


PS. Just noticed this is your first post.  Welcome to the forum, we're usually over in the East Neuk of Fife but are currently down in Berkshire enjoying our granddaughter's first Christmas.  Why not nip onto the new members section and post an introduction, you'll get some more welcomes.

Later ones were wired off the van 12v system

Hi, and thanks for reply - agree that don’t think it’s necessary.
Thought we would share experience we had after being on approx 5 trips we started getting very loud noise from engine especially in higher gears. Had booked into local garage but as I took it there the van totally broke down - in gear but no movement. 
After much toing  and froing with garages , the agent we bought van from agreed to look at it - apparently something called the clutch flywheel was broken - fortunately we had warranty through Momentum and the garage identified issue and it was covered by warranty.
We now have our Rienza back and heading to Newquay area next week.
The East Neuk is a lovely area and you should try Upper Largo Park when there - very open location but wonderful views and lovely meals and beers in the hotel in Lower Largo.
Take care all, Steven and Mary
