Some symptoms of a car alternator failure include dim headlights, a drained battery, or the inability to start the vehicle. The alternator powers all aspects of the electrical system once the engine is running.
In a 1999 Honda Prelude, the alternator fuse is a protective component in the electrical system that helps prevent damage to the alternator and other electrical parts in case of a short circuit or overload. It is typically located in the fuse box under the hood or in the cabin. If the alternator fuse blows, it can result in the alternator not charging the battery properly, leading to electrical issues and potential battery failure. Always refer to the vehicle's owner's manual for the exact fuse specifications and location.
A generator failure warning on a BMW 745i display typically indicates an issue with the alternator, which is responsible for charging the battery and powering electrical systems. This could be due to a faulty alternator, worn-out drive belts, or electrical connections that are loose or damaged. If the alternator fails, the vehicle may run on battery power alone, leading to potential breakdowns. It's essential to have the vehicle inspected by a qualified technician to diagnose and resolve the issue promptly.

Your battery does not supply electrical power to the vehicle it simply stores it. The alternator is what recharges (replenishes) the power used during cranking. You need to have your charging system checked to verify the alternator is working and at the same time you need to have the battery diagnosed as draining your battery completely repeatedly can cause premature failure.
Battery dead , or poor battery cable connection
Electrical Failures But Engine Continues to OperateAlthough it is possible, it is not very likely because with an alternator failure, the battery will become discharged, and eventually will "kill" the ignition and thus the engine.This sounds more like a fuse or relay failure.
Bearing failure. Have the alternator tested. describe the whine - is it proportional to the speed? It oculd be because of the load and the charging - how is your battery condition? Did it do this before? Bearing failure. Have the alternator tested. describe the whine - is it proportional to the speed?

Starter problems can be caused by several things: Weak battery because of battery failure or alternator that is not charging the battery. Falty connection between the battery and the starter. Solenoid failure or bad connection on the solenoid. Starter failure. Neutral lockout switch failure. Bad connection between keyswitch and starter.
Preexisting Condition?I suspect that the same thing that caused the "old" battery drain, and/or failure to charge is causing the battery to be discharged after your replacement of the battery and alternator.Without doing a "hands on" troubleshooting of the charging circuit, and all the circuits of your vehicle, no one can tell you the exact defect or cause. There could be one or more of many causes.The proper "fix" for this problem is for someone who KNOWS what he/she is doing [a qualified Electronic or Electrical Technician to do a complete troubleshoot of the vehicle's electrical systems.During that analysis, the defect should be identified and properly repaired. There are many possible causes that make this analysis is an absolute necessity.
According to the owners Manual, this is an indication of an alternator failure.
battery no longer can store a electrical charge, a charging system failure, a parasitic draw,
