The car may need a new alternator.
Vehicle charging voltage too low or too high or monitor circuit faulty. Check battery with voltmeter.
Take your vehicle down to the local AutoZone or parts store and have them check the voltage output of your alternator. If it's to low/high, this will cause your light to stay on.
it takes 1 C type battery <><><> That answer is not really very helpful because the question doesn't say what the voltage of the light bulbs is! This question cannot be answered without knowing at least the voltage of the light bulbs and also the voltage of the battery that is being asked about.
voltage regulator, sometimes its in the alternators, advance auto parts doesn't replace them in remanufactored ones.
Sounds like battery/alternator problems. Check battery first, it's cheaper to replace.
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.
If it is undercharging the battery yes, but if it is overcharging the battery no in most instances. If it fails completely the light will come on.
Does alt. light stay on after car is shut off? If so could be voltage regulator is defective and overcharging battery when running Does light stay on after car is shut off? If so could be a bad voltage regulator--if so may be overcharging battery Check voltage readings at battery should be around 14.2 with car running -- if much higher than this voltage regulator is bad.
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
Your battery has low voltage and needs recharged, check for loose battery cables, if the light stays on have your alternator checked.
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
