Battery light problem on the board

A few days ago the light of the Battery of the board was turned on, indicating that the car is working only with battery, I found the problem was the alternator that was not generating. The regulator changed because the coals were worn; And I am generating well, the problem is that the dashboard light is not removed and I don't know what to do now, I reiterate the alternator if it generates. What will the problem be? .....

What car are we talking about? It won't be by chance Opel Corsa D, Kadett D, Astra D or Vectra D? Because it is possible, that the battery charge light goes through relay and that it is the relay that fails. (Eye, only in the case of the diesel Opel with Isuzu motor), another thing that may be happening is that you have connected something wrong in the alternator, positive of loading light in the terminal of the account of the feature vueltes, or that the regulator of the alternator is bad already despite loading, does not turn off the light.

You could try to put the contact without the connected alternator cables, if the loading light continues with the cables hanging, obviously the problem does not have it in the alternator, but in the electrical installation or instrument chart.

All the best.

Look, I don't know what car you are talking about, I would like to know what car is and the alternator's mark. But commonly the problem you have are the common triumphs
