    Alternator overcharging the battery

    Since few days have been noticing a weird thing on my Palio Stile 1.6. When the car is idle or is in slow motion, the lights inside the cabin as well as the headlights are dimming intermittently. Also i can hear the blower speeds increasing all of sudden and then dropping to normal. Have seen this issue more prominently when AC is off.

    On further investigations, checked the battery power and found when I race the car, the battery is getting charged upto 15.6 So seems like the Alternator is overcharging the battery :(

    Either repair or replace the Alternator

    I have asked for repair but my mechanic says the repairs cost a bomb and that same cost i'll get a refurbished one in exchange of mine. There is one available for 3k

    This would be the 2nd Alternator change in my Palio :(

    Thats the key fitness mantra for cars to have a longer & healthier life

    Such cars will have less spare parts replacements as mechanically they're strong while cars that run very less seems that adverse effect on the life of the mechanical / electrical systems :(

    Reminds me thats just like our body fitness

    --UPDATE--

    Finally replaced the Alternator to a newer one which is more like a assembled one. The Alternator shop guy said the main parts - rectifier and regulator are originals from Bosch.
    However the Alternator went kaput in just few days. Saw that the Rectifier portion got melted. The Alternator guy said water seems to have seeped in causing a short circuit. I told him the car didnt went in knee deep water or anything like that but that didn't convinced the guy. I had no option to accept it and get it repaired. He replaced the upper part that holds the rectifier and regulator.

    So far its running fine now.

    Just to confirm one thing, when the car is idle and head lights on, as i tap on the Brake, the headlights get dimmed. Happens even if i roll up the power windows switch. Is this normal? If a problem, then what's causing this?
