Thought I finally knew the reason my Smartcraft Fuel Link gauge would never work. It says "Fuel 2" on it, and I just never noticed that before. I thought the fix would be simple....connect my sending unit wire to the blue/wh stripe instead of the pink/wh stripe, disable tank 1, enable tank 2, change it to fuel tank, and program the gallons in it. My gas tank is full right now. What happens is it will not store the size of tank I have. I do tell it the tank is full but it refuses to let me store the tank size. Always shows 0.0 when I go back to it. I have done many "master resets" on my tach and speedo. but that is not the answer. I have tried calling tank 1 a 2 gal oil tank (no sensor hooked up) and tank 2 my fuel tank, and I have now seen the link gauge needle go to "full", but it thinks, for some reason, it has 136 gallons in it (but fuel 2 still still shows 0.0 capacity).
Fuel 1 programming will record my correct tank size and give good readings in the Speedo bar gauge when hooked up to the pink/wh strip wire. That is where I have it now.
I have no idea why my programming in the Tach will not let me record tank size for tank 2. I think it would work right if I could get it to record that.
Right now, I think I am ready to buy a new fuel gauge that will work as fuel 1.
Mercury 2.5xs, system sees it as "25".
Any ideas or comments welcome. Thanks
