Battery is not recharging. I have replaced alternator with a used one from a wrecker but the problem persists. I will do a voltage check (over 13 to 14 volts from alt) when I get a day off work. Could anything other than alternator cause battery to lose charge like this? Thanks, CHRIS 1992 Nissan Maxima

Depends on the battery. What is the battery voltage when the engine is off? If it is below 12v, replace or recharge it.

Make sure that the gauge is accurate and the battery connections good and clean.

Check fuse 13, which provides the field voltage. Also check the 120 amp fuse link for the charge wire.

Run this by me one more time your Post doesn't make sence. Is Battery light on? Is alternator working properly 13 to 14 Volts You Must have a fully charged Battery to test. Get tested at your Local Auto Parts Store after charging

11.88v is too low.

check your alternator and then recharge your battery

Check your battery voltage it should be 12 volts then start it and check the voltage coming out of the alternator it should be 13-14.9 volts.If the voltage coming out of the alternator is less than 13 volts replace the alternator.If the alternators voltage is within 13-14.9 then its time to replace the battery.

check your battery voltage it should be at least 13 volts with everything turned off. If not recharge or replace battery and test alternator , If voltage is ok check for dirty battery or loose battery cables..If all is good ,remove starter and have tested (auto zone will do this for free) please leave positive feedback if this is helpful

It could be the battery. Check to see how old is the battery. Sometimes batteries have punch out dates listed on them to show when it was purchased. This will let you know how old it is and probably need to be replaced.

There's no reset for a battery light (alternator), check voltage at battery with engine running, that will be alternator out put voltage, should not read less then 13 volt's, also check voltage at back of alternator, on the big wire, should have no less then 13 volts also, if voltage is less then 12.6 volt's there, bad alternator, will have to be replaced again, if voltage is good there, but not good at battery, check for bad fuse or fuse link, hope his was very helpful.

first of all make sure you are getting 14 volts from alternator when running, at least 13 volts or more with engine off. if the readings are off, check alternator for replacement or repair. if the alternator fails it will not recharge battery. that is why your gauge is low reading. check voltage at battery with engine on then engine off.

Using a voltmeter check the battery for voltage (12.65 volts) then locate the alternator and check the large wire terminal on the back of the alternator for voltage with car running the voltage output for the alternator should be at least 13 volts if not replace the alternator.
