I have a isuzu bighorn 3.1dt 1997 ,i have never noticed before because i usually dont get so low on fuel but warning light is not working any ideas ? i have heard that there is a switch somewere like gearbox is this true ,
Many thanks

The fuel warning light works off the fuel sender unit that sits inside the fuel tank. The sender unit could possibly be faulty or it could be as simple as a faulty bulb on the instrument cluster. It doesn't have anything to do with the gearbox. A good auto-electrician would be able to determine which part needs replacing.
