Re: Fuel Gauge Problem
I would say with 44 ohms through the sending unit to ground, its telling me you have 1/2 tank of fuel. So gauge should read 1/2 tank.
Tan wire tied to ground, gauge should read empty. Tan wire with a 90 or 100 ohm resistor to ground should read full tank. Of course, all these actions/resistance values connected, with power on, gauge should indicate the cheated level.
In your first post, you said 90 ohms, appiled voltage with key on, and gauge went past FULL. Personally, I found the final FULL indication about three marks past full if gauge was in the cluster. On a console gauge, I would think it would indicate just past F. So I said to clock the gauge, meaning if the needle slams against full rather than rest against F, and if gauge reads something other than alittle more than half (44 ohms), then I would think the needle needs to come off its axis and get pressed back on in the proper spot, mechanically align the needle to the scale to match its electrical input or current flowing.
The gauge has two coils, and the resistance value, 0-90 ohms of the sending unit, determines the amount of current through the coils creating a magnetic field and this field "pulls" the needle weight/axis to indicate on the scale.
I believe console gauges have three posts on it? One for 12V input, one for ground, and one for sending unit. All I have is for a cluster gauge, no console gauge. Your 44 ohms into the harness to the gauge, if I read correctly, should not be there, unless the gauge(?) resistor is there and you're reading it, but still, shouldn't be ohms there to ground. I would really rather not get inside the gauge. I may be too deep into this thinking.
Of course, I too could have too many ohms..............
