Fuel Gauge and Turn Signals Stopped Working

[Agarden7]

Hey guys, Ive searched for everything related but couldn't find my same problem. 1967 Square.

Two nights ago, I lost my gas gauge and turn signals. The gas gauge needle dropped all the way down and is sitting on the housing essentially. Also my turn signals no longer flash in the dash or on the exterior of the car. The wipers work, headlights work and shows the indicator light in the same gauge. Hope this is a simple fix. Does anyone know what caused that? Thank you all so much!

Probably the gauge case isn't grounding well. Some have a dedicated ground wire, I think, while others ground through the pair of leaf springs that hold it in the dash receptacle. I'd try adding a temporary jumper wire as a ground and see if that makes things work. If so, remove the gauge and work up a permanent ground wire.

It's possible that the black wire from the back of the unit came off the fuse box.

I suspect bob is on the right track but if what he said is the case, then also the oil and generator lights wouldn't be working either.

I only have a Bentley. Latest wiring is 68 .

If it was sudden and everything worked before you are going to need to find the grounds and power that supply those circuits . Check at the fuse box just to see if any connectors look suspect . The bulbs in the fuel gauge housing don't draw much current , the gauge and turn lights do.

I'd check the fuse box , drop it down and take a look . The fuses at the hot side with the fuse out are before the fuse and some are bridged where two to three fuses get power from the same source then the fused side goes to each fused component . If for any reason there is an issue with the fuse box it can cause a sudden loss.

If you have a wiring diagram for a 67 it should show which fuses bridge.

If it were a ground I can't see it affecting all the outside turn lamps, most of those grounds are near each lamp .

My advice is disconnect the battery and drop the fuse box and have a good look. It's at least a starting point.

Check for a blown fuse.
