If there is a leakage current that is flowing even with the ignition switch is off then you will always have a battery problem specially when you dont use your car for long periods.Assuming that you already replaced your battery and alternator.you can try this turn ign. off all accessories off and disconnect the neg. battery terminal put in series any 20Amp capacity ammeter.A good system will only indicates the backup current for the PCM, radio,Pats, door module if any,total roughly below 100milliamps.

The battery cables may be bad. Sometimes they look good on the outside, but can be corroded on the inside, and no longer work properly. This happens fairly often, especially in cold climates. I hope this helps.
Good luck!

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.

We have a 2003 ford expedition...Last year we put in a referbished alternater and the battery light came on and we took the alternater back 3 times and they tell us it is fine but now the battery is...


I don't know for sure if your vehicle has the voltage regulator built into the altenator, A parts store could tell you, But if your doesn't then the regulator is in the ECM (computer). Sorry to say but that can't be fixed, At least by a garage. You will have to replace the computer to solve your problem.

1996 dodge wont start keeps draing batteries


sounds like an alternater problem. the batt is not charging and is only running off the batt untill it runs out. check the wires ect on the alt and if that doesnt work, get a salvaged alt.

The car wont take a complete charge


If able, ck the charging voltage at the battery. The alternater should be charging the battery between 13,6 to 14.2v. The lower the voltage the more its charging. Make sure both battery cables are clean and tight. Good Luck.
