    Default Mehran Headlights draining battery like hell

    Update: Sold out my mehro

    Hi Experts,

    Another issue I am facing now a days: My Mehran 1996 is running fine for all day long and even starts fine after 2 days. alternator is charging normal. But I noticed that when travelling at night with headlights on, Battery is totally drained even car is running. I also noticed minor missing while headlamps are on. Last day while coming back from fortress it just stopped in our street and won't move the self. I checked with meter and voltage was 11.85

    I then charged the battery by attaching it to my UPS and charging for 10 minutes and put it back in car and it started fine. I suspect something wrong with headlight relay or wiring.... This only happens when I drive with headlights ON.

    Anyone with any idea what could be wrong and how can i fix it myself?

    do the easiest thing first. take a thick wire,from alternator to the positive of the battery. the wire that comes default with the setup develops resistance over time and can cause what you are experiencing. also make sure car negative terminal has enough/solid ground connection

    just for future reference, when anyone says that the resistance of the wire increases, they are giving you an excuse, why? because it takes time to sort out problems of this kind, they prefer a jugaar fix rather than fixing the real issue

    only things that go bad are connectors and contacts

    In my case the culprit was the wire from alternator to battery. It was so rusted and almost broke 95% of strands so the electrician removed rusted piece of almost 1 foot and replaced with new thick wire. This made good affect on the charging.

    Could be many things
    . Battery faulty (cell short)
    . Alternator fault
    . Some connection leaking voltage.

    First thing get battery checked for SG and post results. SG should not vary more than 0.50 from cell to cell.
