SOURCE: alternator is not charging the battery

You have fuses under hood, one should say "alt" I'd check that as well as in the vehicle also.

SOURCE: engine heats up & then alternator charge is

Check/inspect quality/condition of cables between the alternator & the positive (+) post of the battery. Also check quality/condition of ground cables & straps between battery negative (-) post and chassis and to engine block. One final check is the alternator's regulator connection between it and the UH (underhood) junction box (fuse & relay box).

There is possibly a problem with your wheel speed sensors; You will need to scan your computer system and watch the wheel speed sensor data to find out which one is malfunctioning.

KUN 26 D4D Hilux...something is draining the battery over 3 or 4 days...Alternater putting in 13.85v but battery goes flat over 4-5 days


13.85 volts is barely sufficient and would indicate an alternator fault if the reading was taken "off-load"..

An alternator is not designed to charge the battery and is incapable of doing so because the terminal voltage of the battery quickly rises to fool the voltage regulator into believing even a discharged battery is fully charged and will quickly reduce the charge rate to a trickle.

The alternator is therefore designed to keep a fully charged battery fully charged by supplying all the current for the vehicle equipment and the output rating is chosen for this purpose.

The voltage regulator should limit the off-load voltage to about 14.5 volts but that is only a small part of the alternator test. A professional would apply a load across the battery equal to the rated output while monitoring the voltage and current. Most healthy alternators exceed specifications.

For a sensible in-service test when an adjustable load isn't available, with a fully-charged battery it is sufficient to start the engine, leaving it to idle and switch on all the vehicle equipment. Fit a voltmeter to the battery and wait while the battery voltage is pulled down by the load - to around 12.5 volts. Raising the engine speed to 2500/3000 rpm should cause the voltmeter to suddenly rise.
13.85 would be just about acceptable "on-load" but in excess of 14.0 volts would be ideal.

Said alternator was bad


Bad alternator means no battery charge. Run the battery down without a charging means no power and engine will die. Charge the battery and put a meter on it to see if it goes to 14 volts with engine running. If stays under 13 volts with engine running, replace the alternator.

Battery and brake malfunction light on 15 volts charging


Battery voltage is high, suspect alternator over charging and affecting the monitor. Connect an external volt meter across the battery and start engine 15volts or above will cause problems. If left charging high, it can shorten the life of the battery and damage electronics of the vehicle, things like abnormal amount of bulbs blowing. All electrical equipment is made to operate at around 13 volts with a percentage tolerance, constant running at a higher voltage will cause damage.

I think I have an alternator problem? The charge needle on the dash guage is spiking to 16 volts off and on. I put a voltmeter to the battery and it is only charged to about 11 volts. With the engine...


Hello
The normal charge of alternator on idling is about 13 to 14 volts. 12 is acceptable but keep in mind it will need attention soon. The needle fluctuates due to the revs of the alternator - there is nothing to worry about. Just look that the charge is always above 12V on idle.

I would have the whole charging system tested with a Volt Meter before you change anything else. You can test the Alternator with a Volt Meter while the engine is running. The Alternator should be putting out between 13-14 volts, anything less and you have a bad Alternator. Check all Battery, Starter, Ground connections for loose or corroded wires and tighten or clean as needed.

Battery is not charging but alternator and battery are testing good


check for bad cell, need a battery tester so it can put load on battery it might read 12 volts till u test.read voltage from alternator batt connection should be more than 12 volts. if its 13 or more be sure wire goes back to battery is charged and connected,

Battery has been replaced light does not go off


You may need to have the error code reset by the dealer. Once the cars computer senses an issue it will lock it in untill repaired and reset. The only other possible problem is you alternator. If you alternator is going bad it is not sending enough power to recharge your battery properly. A new alternator can be replaced for under $200.00. Lets hope it is just an error code that needs resetting. Take care and please leave me positive feedback. It means a lot to me. If you have more questions do not hesitate to send them to me. I will do anything I can to get you taken care of. Have a good day.

Normal charging volts are about 14.5, 13 volts is too low. The spec from Ford is 14.1 to 14.7. Broken wires or a bad connection are common.,
