Hey Chris==Make sure the belt is tight. If it is, it can be problems inside. GoodluckJoe
Spark Plugs do not affect your alternator. As long as your engine is running then it should be charging unless your alternator is bad
The charging system is the alternator which is on and functioning anytime the engine is running. If not, then you have a problem with the alternator.
If it is running on the battery only then that means the alternator is not charging the battery.
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
Yes, because a bad coil will not allow the engine to run. But if the engine is running then the coil has nothing to do with the alternator charging the battery.
If the alternator is not producing 13.5 to 15.5 volts it is defective and needs replacing.
bad alternator ? its not charging the battery
The battery light indicates the system is not charging. Have the charging system checked. If the alternator is not charging, the engine will quit running and leave you stranded.
A quick way to check alternator on any vehicle is while engine is running,carefully touch a screwdriver to the spinning part (armature) of the alternator. If it is magnatized, it is charging. If not then alternator is not charging. The voltage regulator (the thingy that tell the alternator to charge) is built into the alternator. Replace the whole thing with a rebuilt unit.
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
Alternator not charging battery due to a bad fusable link?
