Ripple and idle

The indicators of my vehicle were starting to come and go. We barely detected the problem, the alternator broke down and started to give more current in between. Instead of replacing the alternator, the electrician made repairs. I think they are repairing the circuit in the charger. Only after that period, there was a problem of playing and shaking in this period. As if there was a fluctuation in the electricity going to the cycle motor. It is not at a level to stop or cause trouble, but it bothers. Idling becomes unstable again when I try to close it with the windows fully closed, that is, when I force the engine that lifts the window again. Can you help with this situation? How can I fix?

First of all, welcome to us. After the charger was repaired, voltage measurement was done, brother. the battery may also be damaged.

Good bye, I just bought the car battery, Charger was just made. Everything is normal 14.4v in measurement. But idling drops to a value of 12.9 v and fluctuates.

well bro brother the connector was changed.

The charger has changed because it is overcharging, it has not changed.

I understood, my brother has repaired the master, but we do not know what he did anymore. Also, remove the battery terminal at least half an hour later and try it like that, brother. will it improve.

I tried it, it does not happen, my brother, The master that comes to my mind and makes me suspect may have used the material supplier industry or bout, because the product does not yield. The dynamic connector of the dynamon seems to be faulty. piece If it does not supply enough voltage, if the electricity goes on and on, the headlights dimmed in the instrument panel and can even fluctuate at idle. I think.

then it has to be overhauled, I think my brother needs to find a place that does his job properly.
