fuel gauge problem

[Richok]

I am rewiring my Ebko/Evinrude and have everything working except the fuel gauge. I have the S (sending wire to the S (sending on the gauge. Grd is to tank, gauge, neg on battery. Pos is from bat to a switch with a pilot light. My navigation guage light is separate to navigation switch. I turn the switch on the pilot light comes on but the fuel gauge goes to full, the tank is empty though.<br />Thanks for any help you can give.

Re: fuel gauge problem

I'd say the sender wire is somehow connected to negative.. <br /><br /> May be a faulty sender, but i'd double check all the wiring first..<br /><br />These two links are straight to teleflex gauges technical pages... First link (pfd) shows you how the troubleshoot the entire fuel gauge system..<br /><br /> http://www.tflx.com/pdf/marfue~1.pdf <br /><br /> http://www.tflx.com/tech.html

Re: fuel gauge problem

Thanks snapperbait for the info. I'm just about back in the water. I found the Teleflex site helpful. I have a different brand of sender unit, I went back and read my instructions again, followed them to a T. I thought I will just try turning the rheostat over and see if that works. You got it, it worked. Thanks Richard

Re: fuel gauge problem

Richard – I did the exact same thing a couple years ago. Drove Teleflex tech support crazing trying to figure it out. They never get it. I don’t remember exactly what it was ... something simple…arggg! Everything will look like it is connected correctly…I used a couple of jumpers and connected the gauge directly to the battery only and it worked…from there I was able to correct the wiring. Arggg!!! Sorry… I think it was the shared grn with the tank…

Re: fuel gauge problem

I found out instructions are not always 100%. The instruction never said anything about the rheostat having to be one way or the other, but I should have known better. I wired the sending unit straight to the guage using another set of wires and moved the float. I won't soon forget this trick. Experience is the best teacher though.<br />Thanks again for all you guys help.
