Wema fuel gauge wrong readings

[Miller]

After hunting around for a twin fuel gauge I ordered a wema one from the us site. On fitting it I found that the gauges will read full when empty..after googling it and not being told by wema it seems that you get us fuel senders and European fuel senders when have different resistance from full to empty.

The only solution to this is to buy the right gauge it says...I ordered it from the us as that's where they directed me and wema uk doesn't list them.

Can anyone offer any other solutions apart from buy the correct sender/gauge?

Some gauges have a switch on the back to read from either US or EU senders. Unfortunately it's more than just swapping wires around as the resistance range is different too.

WEMA have just replied and their reponse was your fault...We can sell you another! It doesnt state anywhere that they do an US and an EU version but I should have known that!!

This is like dealing with the Inland Revenue!!Nothing is ever their fault either!

Sorry to hear of your issues..... Have you spoken with Wema UK yet? Chap called Stuart who I have found to be incredibly helpful

I think the cheapest way out would be to purchase some US senders to fit to your tanks.

I ordered from the WEMA US site as there wasnt any multi gauges shown on the UK site..I can try on monday..

As for fuel senders, can I get US spec ones in the UK anywhere? It would certainly be easier to swap the gauge than the senders

Hi
Go and see Paul at western electrical marine, (on the way to Yacht Haven Quay) i got mine there.

don't know about mercury but with yamaha gauges it will run all 3 sender ranges -
yamaha own 5-105 ohm. Yank 30-240 ohm. European 0-180 ohm. On the yamaha gauges you either set gauge using dip switches on back of gauge or go into set up mode if newer digital gauge. I will be surprised if mercury aren't similar. cheers

Had this issue when I needed to replace the fuel gauge on our RIB, but the other way round.

Turns out, XS installed a US sender in our UK built RIB

When I told Force4 (which is where i bought it) they said they'd order the US version, and exchange it for the UK one I had.

It really confused our staff for a weekend while I had the UK one fitted

With mercury Smartcraft stuff you can calibrate them to whatever senders you are using.

cheers, i thought that would be the case, will save the op some time/money if he can work out how to set it.

When I built my boat I rang Stuart, told him it was to suit Smartcraft gauges and gave him the depth of my tank and they made me senders to suit.

WEMA US probably don't deal with the UK version - As others have said talk to WEMA UK and they will sort it out or change the settings on the Smartcraft if possible.

[Miller]

Well, all sorted, WEMA UK will change the gauge over for me if I send it back to them....They are nothing to do with WEMA US but their customer service can certainly teach the yanks a thing or 2!

[Miller]

Well, what service from WEMA UK, I sent them a gauge I didnt even buy from them and they changed it over FOC and sent it back next day..

So, A big thumbs up to WEMA UK

[Razorbill RIBs]

I had cause to speak with Stuart at Wema a couple of days ago and told him that this thread was running and of the wholly positive feedback he had received from several of us...

In stark contrast I have been trying to deal with another manuf /distr. today (who will remain nameless).....I wonder why the basic principles of customer service are so anathema to the approach taken by some people? Grrrr....

[Miller]

In stark contrast dont bother with WEMA USA!

Not sure that's true, for Smartcraft they must be US spec senders and the Uk ones work differently.

The cheapest : unscrew your console gauge receiver and half-turn it, then re-screw !

Your problem is the way of the Resistor variation of the tank gauge, with one model the resistor value is maximum (approx 200ohms) when the tank is full, but with the other it is minimum (approx 30ohms) going toward the 200ohms value when the tank is empty.

Spent 2 days fighting with wiring
Biggest issue is the wema readings 0 - 130 om,s both uk senders from force 4 1 x new gauge from a member on here another from some other member and yet another gauge I had in stock, all set ups give me a full reading when empty, am I doing sumat wrong?
