Astra 2005 Electric Failure 2.4

I have an Astra 2005 engine 2.4, about 2 months ago I almost flooded the car: 1st began to fail the ignition I did not go the 3 or 4 attempts on, now the velocimeter needles, revolutions, early It makes hard. He takes it to the electric and apparently everything well, the detail is that the battery warms up in the terminals, checked him with a Scaner and he did not record any fault. They could give me a little hand that happens to my car, greetings.

Good day friend I know a little about these vehicles Some failures such as yours are in detectable with scanner I recommend checking the insulators that the alternator internally possesses and removes all the cables of clean earth, lubrica and then reinstall of the improvement of improving your car I hope to tame my advice my advice
