Yup, that won't be enough as it is normal battery voltage. You need 13.8 to 14.8 or so. Pull the alternator and get it bench tested. Alternators have diodes inside (one way valve for electricity, that converts alternating current to direct current, which your car is). and these diodes fail and leak. There is a set that turns on the regulator that fail..

All will have the same result. rebuild the alternator.

If it bench tests okay, be sure to guarantee good ground cuicuit.

SOURCE: new battery and alternator. Battery still won't hold charge

Check all your fuses if you had a system failure it could have blown a fuse. I am not sure on your vehicle where the fuse is in the car or under the hood it could also have a relay. You can check your alternator by checking the voltage at the back of the alternator where the big wire bolts on. You should have 14+ volts at the alternator.

What place verified the alternator for you?
If its a place like Autozone,all they can do is a normal running check of it,They cannot put a load on it to see how much it can put out.It really sounds like the voltage regulator is not changing,maybe one of the diodes are bad in the alternator.

The battery on my rhino loses volts when driving .battery dies then i have to boost it..something is drawing on the battery when the key is off ?????????


If the battery is not being properly charged while unit is running, it will go dead. You may have a problem with the voltage regulator or magneto causing the no charge issue

Charging system failed. Why is new alternator output ranging between 11 1/2 and 12 1/2 volts?


11 1/2 to 12 1/2 is not charging . That's less then battery state of charge , Battery stat of charge should be 12.6 volts , when charging with a volt meter you should see 13.1 to 14.1 volt at the battery posts . Is there a battery symbol lit on your instrument cluster ? Is there battery B+ voltage at the wires hooked to the alternator How to Test an Alternator

Had my alternator rebuilt, but batteries still go dead.checked alternator shows charging at 11.9 volts then jumps to 15 volts after 2 minutes. is this the alternator


The alternator should be showing at least 15 volts when running! Anything lower would indicate the alternator is at fault, since you say it is showing below 12 volts even for 2 minutes indicates a fault.

there still could be a fault with the battery not holding its charge or something draining the battery like a wire shorting or trunk light staying on that is making the battery go flat!

Will not charge


you will get some funny answers from some of these "experts " The symptoms suggest to me with out much doubt that the regulator is not doing its job correctly ,consistently.Iwould take it to an AUTO ELECTRICIAN and get it tested in situ.... there is only 4 things it can be , wireing ---battery---alternator-----regulator and of those the reg. is the only one that chops and changes. it will cost little for a sparky to check the reg ,. AND I WOULD LIKE TO KNOW THE OUTCOME

My 2005 ford explorer check charging system warning light


if charging light is on w/ engine running,the fault could be the alternator or another component of the charging system.remove, clean and tighten battery post connections to check for alternator output,use a volt meter or multi-tester set to 50 Volts DC,w/ tester on battery terminals it should read 12 volts W/ engine off;13 to 14 volts w/engine running.if voltage increases when alternator is spinning,suspect battery
