Evening All,

Hope everyone had a good Xmas.
Wired up my instruments today(Greengauges) everything worked fine except the fuel gauge. I wirede it up as per instructions,but when ignition is switched on the fuel gauge shows full although the tank is completely empty.

Any help/advice gratefully welcomed.

Regards

David

It sounds as if the wiring to the sender is going to earth,or the float is stuck at the top.
You may have trapped the wire or not quite wired it correctly on the sender.
Have you got the earth and sender the wrong way round?

Had this with my Greengauges unit. Did you download the instructions for the sender unit ? I think the instructions are wrong I followed instructions to the letter and had the same problem, in the end I turned the float unit upside down , the gauge then worked the right way but had to then "calibrate "the sender to give accurate readings . Greengauges were not helpful . Don't suppose we are the only people to have this problem. HTH

The instructions are wrong David.

The little box at the end of the sender arm needs to be upside down.

Bugger I know!

Another one that found out the hard way Pat?

I had the same problem, and I thought it was me

Are Greengauges expensive? - for the measely price of a 4p photocopy you'de think that problem was easily corrected or are they running on a shoestring?

This is not a plug for ETB instruments just thought id add that there customer service is great i had to re calibrate my speedo will at the sva and they did it over the phone . They just gave my a new figure to punch in and hey presto it worked and it was a SVA pass.

My Greengauges instructions were very clear that you had to mount the sender a specific way up and I got it right first time...

Well my Greengauges instructions were very clear BUT WRONG. As I don't appear to be the only person to have had problems I suspect Greengauges have corrected the inaccuracy in the instructions . It still doesn't change the fact they were most unhelpful when I rang them to enquire about fault .I for one am happy with the instruments but not the company staff.

Evening All,

Thanks for all the advice/suggestions. I've tried them all but unfortunately the gauge still shows full when ignition is switched on. The pointer will not move from the full position when the sender arm is moved. Don't know what to try next.

David,

Do you have access to a test meter? If so, check the resistance of the sender in various positions. It should range from 10 ohms to 180 ohms (180 = full, 10 = empty, I believe).

At least you will then know whether it's the sender or the gauge...

David

P.S. Whereabouts in the country are you? The reason I ask is that I have a spare greengauges sender that could be used to test...

P.P.S. Just thought of another test - take the connecting lead that connects to the sender and touch it to chassis; the gauge reading should drop to zero. If it doesn't, you may have faulty wiring - do the same at the gauge's connector - if the gauge now drops to zero, your wiring is definately wrong. If it doesn't then your gauge is suspect.

When you tried moving the float arm did you have an earth wire connecting the float sender unit to a good earth? Is fuel tank earthed?plastic tank will not be. Can't remember which way the float sender resistance works but try earthing the main sensor lead . Most fuel gauges work so that when empty resistance is higher than when full , i e when sensor lead is earthed gauge will read full

.

Evening All,

Thanks again for the responses. I took the sender unit to my friendly autoelectricians who ran a test meter over it. Although it is brand new its apparently k******ed. Unfortunately I bought it from Greengauges in August 2004 so it looks like I'll have to fork out for a replacement.

Regards

David

Happy New Year.

Good news!!!

Just found out there is a 3 year warranty on Greengauge instruments.

just a quick question, were the other gauges you bought from greengauges good quality??

Happy with mine , delivery was good but aftersales left a bit to be desired.

In my case, the after-sales support was excellent. It probably depends on the direction the wind is blowing up the Welsh valley!
