Check fuses if good check voltage directly at altanator must be at least 12.9 and not over 14.9volts

    I replaced the alternator and the passenger side is getting a good 14 volt charge, however the drivers side is only showing 11 volts. There is only one 4 gauge wire connecting the two batteries and there is no bad places in it.

SOURCE: The battery isn't charging some

Have the battery load tested to determine it's ability to take & hold a charge. It could have a bad cell that will drain the good cells. Your local auto parts will test the battery free of charge.
I hope this helps.

Battery good, alternator good, starter good but my 1966 oldsmobile the alternator isn't charging the battery


Have you replaced the voltage regulator?
Unless you have changed the charging system and eliminated it, the alternator does not have a built-in voltage regulator like the newer ones do.
Be blessed.

Why does my battery light come on in my '02 trail blazer


It's usually on if the alternator isn't charging. You'll have to connect a voltmeter to the battery terminals. If it reads 14 - 14.5 volts you'll have to look elsewhere. If it reads below 13 volts the charging system is not working. The alternator is quite often the problem.

2001 mercury sable will run but won't charge and no batttery indicator light in dash will not light


If it runs you have one of 2 issues. 1. The battery is bad and the alternator isn't able to keep it charged (you will have to jump start it every time the motor is shut off). 2. Your alternator is bad and the battery is running the car (when battery is drained car will stop running) which is my belief as the battery light only comes on when the alternator isnt charging. Have the charging system tested at your local AutoZone/Advanced Auto parts store they normally do it for free.

88 Izusu Trooper II with 274000 miles Battery warning light comes on when first starting and running- after driving awhile, it goes off and starts charging- also during the warning period- the blower


Sounds like your battery isn't charging properly, first thing to check, is your alternator belt slipping, is it tight enough, if so does it need replacing?

Next the battery, if its over 2 years old it could be on its way out. Does it hold its charge?

Finally, Alternator, is it still providing a charge for the battery? Are all electrical connections good and clean?

Truck will not turn over, gauges all come on but nothing from the engine, acts like dead battery but it is brand new...it did it before and was told it was the battery, put a new one in....worked great for...


your charging system isn't working, if you replaced the battery and it worked for a few days, then its not being re charged after starting, I'm assuming you cleaned and tightened all the battery post connections when you installed the new battery , if not do so ,, charge the battery from an outside source, once you know its fully charged,, use a meter, and start the car ,, check the voltages at the battery posts,, you should be getting a reading of 13.5-14.5 volts, if not your alternator isn't charging the battery

I have a starting/charging issue in my 2008 Raider that mechanics can't simulate. They have checked for load issues and found none. Please advise.


first,, take the battery out of the vehicle and have that Load tested on its own, sometimes the battery will say 12 volts and still have a dead cell, which means its not getting the amps required ,, and will give the effect that the charging system is failing, make sure all battery connections are clean and tight . Once you have a known fully charged battery ,, install it, start the vehicle,, check the posts again with a meter,, you should get a reading of 13.5 - 14.5 volts showing, if not your alternator isn't charging the system

Battery won't hold a charge, suspected the alternator might be at fault. Then all the relays went absolutely haywire! Even without the key in the ignition, all the relays will click on and off, it's...


If your alternator isn't charging, it will drain the battery to a low enough voltage where relays will "chatter". I suggest you get the charging system checked, and it wouldn't be a bad idea to get the battery load tested to see if it's still sound..
