i had smilar issue with my 99 mitsu mirage, changed alt, and battery, and still had problems, turned out to be the voltage regulator. To test use a voltmeter and if the reading is below 13 on a new battery and is fluctuating then it should be the volatge regulator Try changing the belt i just had the same thing happen to my 03 rs i change both belts and then everything turned out fine after that
Voltage regulator or loose wire.
Most likely the problem is your alternator....the battery light actually does not monitor battery condition, only the charging system. I'd check the voltage regulator and the fuses first. The fuses are the cheapest fix and the voltage regulator will run about 25% less than an alternator.
you may have a bad battery or a bad voltage regulator
The ground cable, on the battery may need to be tightened or cleaned. The alternator voltage regulator may need to be replaced.
Bad alternator not charging battery? Bad voltage regulator? Blown fusable link?
The vehicle should ave a voltage regulator. If the battery and alternator are good then the regulator is most likely bad.
does the kia have a remote voltage regulator
On most vehicles today the voltage regulator is built into the alternator. If that is the case then just replace the alternator. If the voltage regulator is external on your vehicle then replace the voltage regulator.
The computer only resets when the battery is removed. The alternator just charges the battery, so if the battery is left connected when the alternator is replaced, the computer should not reset.
it could mean that you have a loose battery cable that needs to be tightened
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
The engine computer is the regulator. It is the black box next to the battery.The engine computer is the regulator. It is the black box next to the battery.
either the alternator or the voltage regulator are no good.may also be a bad battery
bad alternator, bad voltage regulator, bad battery, bad connections.
Have you checked the fuses?AnswerMay be a bad voltage regulator. alternator is no good without a voltage regulator. that's what "turns on" the alternator.
Two things can happen. 1. the voltage regulator fails so that the alternator doesn't know the battery charge is dropping therefore the battery doesn't get charged. 2. The voltage regulator fails in such a way as to allow the alternator to overcharge the battery which causes the battery to overheat and fail, Sometimes an overcharged battery can explode.
faulty voltage regulator
Defective voltage regulator.
Alternator is bad or your regulator if is not built into your alternator
the only thing that is left is the regulator which should have being replaced first in the first place Rocky_B - See my entry here for more things you might want to check: http://wiki.answers.com/Q/What_could_be_wrong_if_the_battery_light_stays_on_and_the_battery_still_runs_down_on_a_1996_windstar_after_installing_a_new_battery_and_alternator
how will I know my Voltage regulator is bad. I have replaced the starter and had the battery and alternator checked they are good. My car will start when it is colder outside but as the day gets hotter it will not start.. Can you help
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.
Red means that the battery charge level is low or that the alternator is not charging battery properly. Check alternator, voltage regulator, connectors.
