fuel gauge light

Post by niro884 »

My fuel gauge light does not work. I have had the tank nearly empty and it does not come on. The fuel sending unit in the tank is new. Is there a a disconnected wire that may be causing this? Or is it the gauge itself?

Thanks!

Did you check the light bulb in the gauge? Also make shure the gauge ground is connected.

I will check the bulb. I assume that if its the bulb it can be replaced? Are you refering to the ground on the back of the gauge or elsewhere?

check to be sure that both the wires on the sender are clean tight connections.

What I can tell by the schematic, the wire coming off the gauge ( red ) goes to connector under colum, turns grey/red and goes thur two more connectors to the sender. One connector is at the lower dash above your left foot in the corner, and I guess the last one is in the trunk. It gets its ground from the sender. Theoretically, if you take red/grey wire off the sender and ground it, the lamp should light.If it does not, backprobe a ground at the colum connector on the dash side, no lite, its a bulb or poor connection ???
