Reattaching wire to Thetford Toilet Flush Switch Circuit board

[Dave W]

Hi,

I've been trying to get to the bottom of why our Thetford C250 series toilet has stopped flushing water into the pan. Following videos on YouTube I located the little circuit board with the push switch under the sticker on top of the toilet and removed the push-on 8 way connector plug to see if the contacts were tarnished.

Unfortunately the red wire has now broken off just where it goes into the connector plug, so I can't go any further until I get it reconnected.

Can anyone advise the process for removing the end of the broken wire from the connector plug and re-inserting the wire that has come out again?

I 've attached a stock photo of the connector I mean - its the red wire that become detached on mine.

Regards

Dave

This is not the best job in the world I searched for a way to do mine as mine broke after the 4th board packed up.The system is worst thing Swifts put into a caravan. Right you can buy the clip on connector complete with wire s Im sure and just cut and re connect . My van in Ten years has 4 new boards dueto the corrosion on the board and block connector . Got fed up in the end and got my service engineer to get rid of the stupid idea and fitted a nice little rocker switch instead . Good luck.

Anybody have a wiring diagram showing wires in the Thetford C250 system. After some pain I removed the pump only to find on test it works just fine. I do not use the cassette full light at all and wonder what each wire actually does?

After 7 new boards in 10years I gave up with the stupid idea of c 250. Picked up thee permanant live in the loom and ftted a nice new small toggle switch. No more red warning light.no more reed switch Simples.

Roger, I have decided to do that, in essence but keeping the switch under the membrane and a bit of thin wire replacing blown PCB track short-circuiting everything, wire from 12V live to pump output terminal! Thanks. Replacing the ridiculous fuse in the base with a water proof one on the cassette side out the way below the pump.

When I did mine I fitted the small toggle switch into the top above the board so the flush is still where it used to be ..
I hope it works for you. Sir Roger
