Valeo alternator, yellow wire?

[billywhizz]

What does the yellow wire do that comes from within the alternator? it does not have a post and nut ,
but comes from behind the little raised grill thing, on my previous Volvo engine this wire had been extended/taken up to the dash and connected to the back of the fuel gauge?

as i have refitted the engine and the fuel gauge already works i don't know what to do with the yellow wire? thanks.

What engine? Be specific. A picture of the wire would also help.

Trust me, fuel gauge wiring does not come from the alternator, no matter what color it is.

That is the sensing wire for the internal regulator.

Just leave it hooked up to the alternator terminal as shown in the picture. Then you know it's seeing what the alternator output terminal is seeing.
