mine is doing the same thing and i have no clue my battery keeps dieing at night
If your engine does not turn off by the key I suggest disconnecting the battery and alternator and immediately fixing what is wrong
Could be internal short or defective voltage regulator (points not opening) located in alternator
turn it off!
The alternator light goes out on starting the engine when both the ignition source, and alternator are producing positive voltage. When the ignition switch is turned off, the engine, and of course, alternator are still turning momentarily. The alternator is then still producing positive voltage, while the 'off' ignition switch has assumed a negative state, creating a closed + - circuit, allowing the lamp to light. This is a very normal state, and has occurred for many decades, even back to the days of cars running generators, prior to the alternator. Absolutely nothing to fear.
You either have a loose/corroded battery cable or a weak battery.
unbolt it, take the belt off, take the wires off the alternator and replace with new alternator.
take the belt off the alternator and take out the 3 bolts that hold the alternator to the engine and unplug the wires that plug into it and you have it off.
Bad bearings in an alternator would make a grinding or roaring sound. If a Diode Plate is failing you might hear a buzzing sound in the radio that changes pitch with the speed of the engine.
If the alternator is working properly then it should go off onec the engine has started. If it does not then you probably have afaulty alternator.
No
There is a buzzing sound from next door.I am buzzing with excitement.
The buzzing sound is possibly the starter solenoid, sounds like battery is low or stater motor is stuck.
