Hi all,
I am having a few problems with and LX fuel sender and gauge not reading correctly. It basically reads just on empty when there is 25l in the tank still and just under 1/4 when there is 30l in the tank. I have pulled the sender out and tested it on the ohm meter following a couple of other posts about it. The sender is and older aftermarket job like you can get from rare spares etc.
It seems my sender is OK, it reads
10.5 Ohms Full
29.5 Ohms Middle of swing
74.0 Ohms Empty
I have moved the sender around whilst still connected to the gauge in the car with alligator clips, the gauge reads 1/2 tank when the sender is reading 21-22 ohms and this doesnt seem right. Does anyone know at what exact ohms the fuel gauge should read in the middle 1/2 tank? I initially thought it was the gauge and took it to a instrument reapir place that tested it on the bench, they said it wasnt too bad and told me 25 ohms should see the gauge exactly in the middle but other posts on here have indicated 32 ohms and I am getting 21-22 ohms which in my mind is very close to 10 ohms which is supposed to be full.
The gauge in the car does read full when the sender is all the way up and empty when all the way down but the middle ground is no good, attached is a photo of the sender position when the fuel gauge reads 1/2 tank. I havent measured it exactly but i reckon there would be close to 40l in the tank when it reads 1/2 on the gauge.
Can anyone shed some light or have any ohms readings on what the fuel gauge should read at 1/2, 3/4 and 1/4? Is there anything else i could be missing?
Thanks
