Peugeot 206 alternator

Hello everyone, my consultation is because I have a 206 16 valves I changed the voltage regulator because I made it measure and it was wrong now three days later the legend of low battery charge appeared again and accelerating load 14 but regulating begins to fall little by little to 12 volt if I accelerate a little is corrected but my question would be Anticontamination anomaly and on the board is that yellow drawing on which is like a good valve thanks in advance greetings

Hello Caalbo, I would ensure that the battery is in good condition (electrolyte and level density), because if it is wrong, it does not limit load and make the alternator work all the time ... the fault of the regulator is very difficult to occur (I do not know how they will have measured it ...) They usually last a lot and the only thing that I have seen in these is the wear and tear of brushes (from 200,000 km). The Ralenti is correct at 900 rpm. You should also look at a possible derivation of mass to mass that is constantly downloading to you .... the "anticontamination anomaly" is already another issue, review the Lambda probe (the resistance of this is not cut or deriving to mass ..), caudalimetro, catalyst state .. A diagnosis of faults that you give you the code, to be able to indicate better. Greetings!!

It will depend on many things if they repaired the regulatory box is fine, but if it does not load it can be that the coals did not change or that the winding does not work properly or that the diodes plate is spoiled, I do not know that they will repair you from the alternator

The theme of the alternator is always related to the coals (brushes): clean the rotor contact (sand 180) and change them.
It can also be the case that the diodes are short, here two solutions: one is that you change themselves one by one or buy the full diodes and collaborate it. In this part, be careful with the isolation washers because it goes loss (it passes me several times)

The problem can be: in the battery, which could be that it is in the sunset of its life and this generates an overload about the alternator who in turn overloads the engine and lowers the turnt turns, it does not sometimes do it to you and other times if in that case it is that it does when it turns on the electroter. The battery replacement solution. Another possibility is that the idle of the engine is low or regulates badly due to some defect of the IAC valve. Normally it happens that it is getting dirty and with remains of dust, carbo and being a medium without lubrication can begin to fail, the solution is to remove it clean it with some lubricant/uninstrusting. On the side of the tensions that the alternator/regulator will tell you that they are correct lñas and has no problems, only have any defect in which a few return below what is necessary to say the RPM of idle are low or decay at some point. Greetings and luck
