D90 low fuel waring light

Has anyone ever figured out how to make the low fuel warning light work on a D90?

Change the gauge? Different fuel pump?

thanks

Hi Cliff!


On UK rovers it's a separate wire from the sender unit (on the tank) up to the dash.

Td5 rovers, the light it controlled by the speedo which has a dampening circuit in it, (to stop the guage from waving about frantically when you go round bends) but it also controls the light.

The NAS model has power going to the dash indicator light and needs to be grounded to turn on. Assume the UK model has the correct ground from the tank sending unit?

I would have thought someone would have done this before, like ECR etc.
youre sure there is power to the light?

I have an old fuel pump/sender but dont see anywhere for a wire to attach

If you open the dash panel to gain acces to the back side of the light and Ground that location (don't recall exactly which one but obvious when looking) it lights up red with a fuel pump symbol. I was wiring my D90 up as as indicator for a transfer pump "on" with aux fuel tank. The hot comes in through the standard panel wiring. Requires a little work to locate/fabricate a connector that fits into the factory socket. Seems the correct "ground" signal coming from the fuel tank sending unit would work? But electrics are not my strong point.
