Thetford C250 Tank Full Light on permantly

[HuDDy28k]

Hello all I have the above Toilet and i have changed the float in the waste tank also the reed switch and reed switch arm but the light is still on permantly if i pull off the wiring harness from the reed switch the light is off but as soon as its reconnected in come back on weather tank is full or empty

Any ideas any one ???

I would just remove the battery. You can see when the toilet is getting full so why they bothered with the light i do not know.

Would have been more use if it told you when the flush water was getting low as you only find out when it's to late.

I was thinking exactly that to !!!!

Interesting - one of my little caravan tinkering jobs for this weekend is to re-solder the battery holder leads so the light works again!

The "Woosie Tank Almost Full" light has never worked in the seven years we've had this van, and it's a minor irritation for me. It's a good point that a low level warning on the flush tank would be a more useful innovation - as the van is now well out of warranty I'll get my thinking cap on and see if I can come up with something over the winter

Gozza - lots of cars have float devices in the cooling system to warn of low fluid - perhaps this might be a source of inspiration. Or thinking some more, the water level indicator used in on-board water tanks? Like you I feel a gadget coming on...

I suspect the quick and easy solution might be a sight glass similar to the level indicators for Aquarolls, like this:

But I'm keen on a more elegant solution if possible - maybe an electronic detector that utilisies the existing "tank almost full" light to instead indicate "flush tank low". That should confuse any future owbers of the caravan!!!

How about this.
