there is no dimmer for the light. How did you check the sender and the fuel guage?

Did you hook up and ohms/guage tester to the harness and induce a resistance for the guage to go to full "full" and full 'empty'?

I checked the sender with an Ohm tester and the fuel gauge at the panel is indicating the right amount of fuel.
There are four wires to the sender. Two for the fuel pump and two for the sender itself. There is not an auxiliary circuit for the fuel lamp. I assume that an electronic circuit gets the resistance from the sender and (when the fuel is low) turns on the lamp.
When the lamp was working, first started to light very dim and then increased the intensity as the fuel decreased.
I do not know the location of that "circuit" in order to test it.
Hope this can help. Regards,
Martin
