Hi. Ive just had my fuel tank replaced, and am having trouble with my fuel gauge sender unit. It was working fine before it was taken out and put back in again, but now I think the mechanic messed with the wiring in a bad way.
There is a green wire (with round plastic end piece), and a yellow wire (with a round plastic end piece) and then another wire which has the usual flat plastic connector on it. The two main wires plug into the unit okay though Im not sure in which order they should be ? But the other third wire is just hanging loose as there doesnt seem to be a connector on the sender unit for it ?
There is a round metal type protrusion from the sender unit in between the other two connections, but the spare wire I have doesnt fit it because its a square connector. Is it the earth perhaps ? Is it supposed to have a connector on the wire which slides over the round protrusion ?
Im really lost and quite annoyed because it was working fine before the mechanic messed with it. When the wires were in one configuration the fuel tank was always full (when half full), then in the other configuration its always sitting just above the red even though it should probably be IN the red. Quite confusing.
Anyway, Im hoping someone knows what Im talking about and can offer some advice.
Thanks very much.
