Brake Light and Battery Light On

    In the two odd years I've been driving this '99 Hyundai Accent, the
    brake and battery light have always flickered in rhythm with the rpms
    of the engine. The one time I had it checked out, the garage gave the
    alternator a yellow, (caution) warning. They said it was still
    working but wasn't in the best condition. Now today for the first
    time, these lights are on and won't go off. Also in the recent past I
    was told the brake cylinders were leaking and had two of them
    replaced. Brake fluid levels seem to be fine as well.

    What should I do?

    Any help is appreciated.

    It seems you already have your answer. You've already been told that the
    alternator was weak, and now your symptoms have gone from flickering to full
    on. How about replacing that alternator now?

    How much do you think that will cost?

    Not so long ago parts like Alternators/Starters could be repaired. New
    brushes, regulators etc. Is that no longer the case? Damn sight cheaper than
    a new replacement.

    How much do you think that will cost?

    Whatever you were told the first time. How could anyone tell you what it
    would cost when prices depend on where you live? You've already been told
    what is wrong by a qualified mechanic, who likely quoted you a repair price,
    which you elected not to exercise. You have all you need - now just go do
    it. Want to try to get a better price? Call a couple of aftermarket stores
    like Advance Auto or Auto Zone.

    Where I live in Central NY John, there is a shop that will still repair most
    alternators for around $65. They are worth looking for in my opinion, but
    most people who ask really basic questions like Chris' don't generally want
    to go this route, or seem stymied by the thought of finding a shop that
    repairs alternators. Easier just to send them to the store.

  7. Alternators can still be repaired, but the time involved is a hassle if
    it's done right, as it should be completely stripped, cleaned and rebuilt.

    It's easier to just buy a rebuilt alternator, then return your old one
    to the seller to recover the "core charge" after you've installed the
    rebuilt unit. It's been a while since I had to replace an alternator,
    but I recall the rebuilt units going for somewhere in the $65-$75 range
    (plus the core charge). It's usually worthwhile to see if there is a
    local rebuilder in your area that you can buy from, but rebuilt units
    are available at most auto parts stores.

    A bit tedious to do but very cost saving, last time I did
    an alternator was in the 1980s for under $5.

    Some of the rebuilt available at the parts stores have been rebuilt in
    China. The cores are then sent to China for rebuilding.

    The last time I replaced the starter on my Dodge truck it was a
    Chinese rebuilt.

    I suspect you have an intermittent /corroded connection
    and there is nothing wrong with the alternator
    is the alternator belt loose?
    I would start by checking and cleaning all the
    electrical connections. On the alternator,
    (ALL of them) you can spray deoxit gold 100
    on the disassembled terminals.
    if the connections have turned black, green, etc...
    clean all the contamination off.
    very often a bad connection will lead you to
    believe that an alternator or other part is bad,
    even when it's still good...
    even a bad connection on the computer
    equipment. this may send you on a wild goose
    unplug the brainbox, relays, connectors and spray
    deoxit gold 100 into all that stuff,
    plug and unplug to distribute the contact preservative
    around, inside the deepest connections.
    going through and cleaning, checking, tightening may well solve
    this problem. use only HIGH QUALITY contact
    cleaner which is safe on PLASTIC! This is made by
    CAIG chemical, and it IS NOT relay cleaner.
    Cheap contact cleaner is inferior and may damage
    (melt) plastic. Relay cleaner will MELT plastic.
    If you have cleaned all this stuff and confirmed that
    there are no loose plugs, etc...
    your alternator can be tested for free at an auto parts
    From what you are describing, I doubt the alternator
    is really bad, although I will not say impossible.
    The deoxit spray is non shorting and does not interfere
    with operation when it's wet. you can spray it and run
    it right away, it's non flammable.
    Generally speaking, repair shops have no clue when it
    comes to automotive electrical, and you are better off
    finding an automotive electrical specialist. Otherwise
    you may wind up replacing a bunch of parts for no real
    verifiable reason, then the problem comes back again.
    Even a bad solder connection on the computer PC
    board could cause this. bad connections can be found
    by tapping, wiggling, etc.. to narrow the area where the
    intermittent exists.

    Beware cheap "rebuilt" alternators and starters. Those cores are shipped
    to China where they sandblast them then send them back and there's your
    $65 "rebuilt". My son and I replaced his alternator 3 times ( a lot of
    wasted labor) and each one was bad. We spent $100 on a name brand
    rebuild and it's still working years later.

    I'm seeing costs of $90-125. I tried to buy brushes for my 99 a
    couple of years ago and was told by the dealer that nobody rebuilds at
    the local level anymore so they don't stock parts like brushes. If
    you want to play you can try changing the brushes on the unit but you
    will have to find some somewhere. They don't seem to be sold to the

    So just a followup. Apparently the alternator was dead. Rebuilt one
    installed was $500Cdn. Didn't have much of a choice.

    I sure hope that included the Vaseline.

    $500????? You are not serious I hope.

    Totally serious. Parts and labour=$500. I called a Hyundai
    dealership as well and it was about the same price.

    Hey I just did what you told me to do.

    Thats not that bad a price. Its so bad on an XG350 that a lot of the time
    it makes sense to go ahead and have the timing belt done at the same time as
    much of the required labor is the same. I did anternators on both my
    XG350's and its a pain!!! Not to mention, the alternators are around $200
    to begin with (this is for a rebuilt).

    By the way, on the XG350 the brake light and battery light are wired
    togeather so they both go on when the alternator fails. I have no idea why
    they did this, but I suspect your Accent is the same.

    Well - you did the right thing by getting it replaced, but that price...!!!
    Holy cow man. The worst I would have expected would have been around $200 -
    $250 US. Then again - I don't pay for repairs so it's easy to get out of
    touch with pricing.
