    2015 Honda accord here. Altenator is reading 14.6 and 14,82. Replaced battery yesterday and still experiencing the electrical issues such as dimming lights and etc while driving. Battery reacts 12.5 and or 13.5. What could be the issue? Thanks

    Hello I have a 2005 Ford Escape 3.0L V6 limited 2wd. I am having issues with my battery overcharging still after first battery got to hot started spewing fluid and the issues below. I had recently gotten the battery a month prior. So since I didn't know what was exactly wrong I took it back and had it replaced. My vehicle ended up having the same kind of issues. Battery not boiling and spewing as before but seeming to get hot same smell as before. When I accelerate loss of dashboard lights no power for windows loss of radio windshield wipers turn signals etc. When I brake they come back on. Next morning car battery was dead so I ended up getting a jump and met the repair guy at the nearest Auto Zone 1.5 miles bought the alternator and serpentine belt he replaced it there everything seemed to be fine but oil was leaking so he suggested we also replace the valve cover gasket this Auto Zone didn't have the gasket so we drove to next nearest which was 4 miles away everything seemed fine but ended up having all the same issues still. Any ideas at all on what my issue may be ?? If it might be some kind of ground or maybe a certain wire cluster could you please tell me where they would be located. I will be very grateful. Thank you in advance and God Bless :0)

      Hey there. Have you checked the alternator to see how much voltage it is putting out? 15 volts and more is overcharging.

    Hi I have a high output alternator and is overcharging the battery to 17 volts . Can it be the voltage regulator in the alternator or the alternator itself that's bad

      Acceptable range is 14.2 to 15.2.

    Now my battery is licking and the mechanic says it overcharging that is why it brings some bubbles outside and cause the licking. I didn’t check the alternator I don’t know how much bolt it sends. But the mechanics told me the battery is overcharging that is why it creates those bubbles coming out. What can be the cause? Which thing should I change : the battery or the alternator?

    Power loss both electrical and mechanical when accelerating. I think the alternator regulator (reads 13-14v at idle, but up to 18v under throttle) is overcharging and causing the gauges, ac, and everything to bog down. I do notice the more things that are turned on the better it runs, guessing from the extra current draw. just wanting to know if anyone has experience with an over charging alternator and does it cause power loss?

    • @Top5AutoRepairs
      @Top5AutoRepairs  Рік тому

      18 volts is too high. The regulator is faulty.

      13-14 volts is typical for a charging range, arrange for overcharging would be 15 to 16 V and more
