I suggest you check the "fusable link".This is part of the battery cable system near the battery or starter. . John In
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.
Battery dead , or poor battery cable connection
unstable idling and battery indicator lights on.
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.
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.
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.
battery no longer can store a electrical charge, a charging system failure, a parasitic draw,
There could be many reasons why your Renault Kangoo will not start in the morning. These problems include battery failure, alternator issues and engine failure.
According to the owners Manual, this is an indication of an alternator failure.
Propably battery not charging - might be bad battery , alternator, or some connection. I had the same problem few days ago, fitted new battery and it is ok now.
The battery symbol light indicates that, for whatever reason, the electrical system in the vehicle is not being supplied with the proper voltage. This is often caused by a malfunctioning battery or alternator. Since the battery is the easiest to remove and replace and is most prone to failure it is recommended that you have the battery checked. This can be done, usually for free, at any auto-parts store.
i would start by testing the battery , i have seen cases where the battery was good enough to start the vehicle but was causing the alternator to do all the work resulting in premature failure. my f150 went through a brand new ford alternator in 2 months .
It would if the battery voltage was lowered enough to cause it not to fire.
If it is a "physical" failure, it'll likely be the bearings that give out - and most times, most bearings will start making a groaning or humming type sound. If the failure is electrical in nature, it is common for there to be no sounds or symptoms like that to give you fair warning. Low voltage resulting is things like starting problems, battery not charging, dimming lights, will be common symptoms of a failed alternator.
A bad battery - one of the 'cells' can fail and cause there to be virtually no reserver: need a jump after leaving lights on for just a very short time.A bad alternator! If the voltage being sent to the battery from the alternator is too high / erratic, it'll drastically shorten the life of the battery.
sense wire has to have 12v on it to tell the alternator to charge - bad/broken wire,,, possible pcm failure.... disconnect sense wire from alt - jump terminal to the battery to see if it charges - if it does - you have found the problem
Have you measured the voltage across the battery with the engine running? It should measure approximately 14v. If not you want to replace your alternator/voltage regulator. Check your shop manual to see if you can open the alternator and replace the brushes. After so many miles the brushes wear down, this is the most frequent cause of alternator failure. there is a fusable link in the line between the battery and the alternator i replaced the battery and alt. but still wouldn't charge track the wire
Sounds like the alternator is not working,or at the very least not recharging the battery because of a wiring failure,so it will run until the battery drops to about 9 volts DC.
I would find a local auto parts store that offers free battery and alternator testing - both of which can be performed with the parts on the car. My own suspicion would be a physical failure with the alternator - bearings possibly(?)
Engine Failure to Run if Battery is "Dead"Yes, a dead battery can not provide adequate electrical power to the ignition system and thus the engine cannot continue to run. Depending on the vehicle and electrical system, this can happen, even if the battery is not dead, but only to "low."
FIRST U Disconnect the NEGATIVE BATTERY Cable then U mark the wires if U have never done one-(with masking tape) the UNbolt the Old Alternator & install the NEW one & make SURE the BELT IS NOT 2 Tight(bearing failure) or 2 loose--- make sure the Battery is Charged UP so as NOT 2 BURN UP the NEW Alternator BY making the ALTERNATOR try & charge a DEAD Battery. -------ZX2Fast-------- Check 'Related Links' for a how-to on alternator replacement.
Bearings can fail or a diode can burn out. Age is the enemy of an alternator.
