Suggest you to vehicle charging circuit for a thorough examination.
The first is to measure the battery tester, suggest you use high frequency discharge gauge or battery measurement, the load current is less than 110 of the cases, the minimum voltage shall not be less than 9.6 volts, and remained stable in 5 seconds. If the voltage below 9.6 volts, but can keep stable inside said in 5, excessive discharge, should be timely supplementary charge; if the voltage below 9.6 volts, to maintain stable and rapid decline to 0 volts or close to 0 volts in 5 seconds can not, indicates that the battery failure.
Then check the generator power output, recommend looking for car condition with a multimeter in parallel with the positive and negative poles battery, the output voltage and stepped on the gas check generator in high speed condition is in the 14V positive and negative 0.25V or so, if the lower or higher than the standards, then the generator failure. Use obd2 tools for automotive diagnostics , you can improve vehicle safety performance and driving more safer.

Battery light stays on after changing battery,alternater & plugin.


Is the system charging? You should have 14.2 14.6 volts at the battery. The charge light is controlled by the alternator internally. If the charging system is working, you could have a bad diode inside the alternator keeping the light on or a short/grounded circuit to the battery light

F350 2004 6.0 brand new alternator not charging new batteries , battery light stays on , what could I be missing?


Just cause its a new alternator does mean it should work. I would check the charge when running cause it could just be a bad alternator.

Alternater went out and I put a rebuilt one on. the hot wire gets hot and so does the alternater after you run the car a few seonds. also the battery light stays on.


I believe the rebuilt one is not good too. If the battery light stays on it means that the system is not charging. Did you connect all the wires the same way

2006 Corolla LS battery continual drainage


difficult to accurately *****, you need to get the charging checked, even though you have a new alternater the problem could be as simple as the charging light not working, which causes the alternater to initiate. or you may have an electrical component staying on draining the battery.

try putting your vehicle on a diagnostic check although you have changed the alternator the ECU ( car computer ) may still think that the alternator is still faulty a diagnostic check will cure your problem by clearing the fault codes on your ECU
