BuffaloBill Posted September 9, 2012 Share Posted September 9, 2012 We have 2 holding tanks with Wema Gauges fitted but neither have worked properly since we bought her. Ours has always read "green" even when full, so last time we were down I took off the panel behind the toilet to see that the wiring connector had dis-connected. I also noted that extra wires had been added to the plug which once it was pushed back in, all the lights came on! And we had just had it pumped out. So if anyone has a wiring diagram for these, I would be very grateful. Photo shows the gauge now with all lights showing. Incidently, I did take one sender unit out as someone said it could be 'crudded up', which it wasn't. So despite working it by hand (with latex gloves on!), nothing happened. Failing a diagram, it means bringing the gauge and sender unit home to investigate, leaving the holding tank open.. Quote Link to comment Share on other sites More sharing options...
Matt Posted September 9, 2012 Share Posted September 9, 2012 Thunder has those. They are erm, erm poo! One always reads full but the other one does work although I don't need a light to tell me it's full! Not onboard again until Easter which makes me about useful as your toilet gauges!

C.Ricko Posted September 9, 2012 Share Posted September 9, 2012 It is fairly normal for this type of setup to not work, Brian Ward sells the bits and I am sure they would help you if you popped in, I suspect the problem is at the sender end which is why the guage was disconnected ...

BuffaloBill Posted September 9, 2012 Author Share Posted September 9, 2012 Thanks Clive. I'll try a phone call tomorrow. I can check the sender out if I know what wire does what! Matt....Time to sell your shares and BUY!! We have spent 70 days on board since 1 January. Easter?... Quote Link to comment Share on other sites More sharing options...

Gordon Posted September 9, 2012 Share Posted September 9, 2012 You mean you don't just peer down the hole and see how high you think the tide is. Sounds like these gauges could take some of the fun out of boating do the gauges work by measuring the smell? or have I missed the point again ?

MBA Marine Posted September 9, 2012 Share Posted September 9, 2012 If you fit the the tanks with a nice big 1.5" vent yr worries are over! flush as often as you like it will never be full!! : now before im hung drawn and quartered- I am joking! Or if you want a gauge how about a garden cane down the pump out pipe! Quote Link to comment Share on other sites More sharing options...

ranworthbreeze Posted September 10, 2012 Share Posted September 10, 2012 We have got those gauges as well, they always seem to go from green to red missing out the amber. One of our owners had to sort out the sensor/float switch on one of our tanks a couple of weeks ago that was sticking. Clive are you wanting to take all the fun out of boating, you will be asking us next not to put anything down the toilet that you have not eaten.

BuffaloBill Posted September 10, 2012 Author Share Posted September 10, 2012 Love the replies. Had a reply from Wema already, so at least I know how the wiring is set up. Thanks fella's (I think...) Matt. You are not paying me for me being a pensioner! I worked for 50yrs without ever being out of work, had only 3 jobs in that time and payed into the system all that time. Unlike some in this country, and some coming into this country and getting everything for nothing..... Sorry Matt! Rant over. No offence intended.

ExUserGone Posted September 16, 2012 Share Posted September 16, 2012 I made my own gauge, a double float switch (all plastic) from rs components, a few relays and a tri-coulour led, push the button to read and green is fine, yellow is getting close, red is crap elsewhere, can't remember the float switch part number or I'd post it, I'd probably do away with the relays now and use a picaxe or similar to drive it. I fitted the switch inline with the rinse fitting so it always gets washed off when rinsing. Quote Link to comment Share on other sites More sharing options...
