Charging promblem installed new alternator and battery , Won't charge

hi Michael.
see if this link helps you out.
alternator won charge new battery Google Search

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

see the diagrams attached and chart, and fix it. God bless you

Probably because your Battery is Bad... Try Charging and LOAD TESTING our battery and then if the battery tests good, Test your Alternator and see if it is charging properly.

Maybe when you installed the New Alternator, you missed a connection or have too many wires on one connector... You have have to take some pics to see what is going on.

look for main fuse panel under hood, there should be a charging circuit fuse check it

Maybe.
It means the alternator is not charging the battery.
The battery could have a dead cell, or the alternator could be faulty, or a wiring problem between the two components.
You would need to have the battery and alternator tested.

if its not charging while running at14.5 volts or so you have a charging problem mabey no power to the alternator if its charging at 14.5 or so and the batery load tests good and its going dead over night you have a draw from some component in the system.

Since you are having a new battery and alternator the charging circuit of the electronic charging unit is a possible suspect.
All what is required is to check the charging voltage when the engine is started, if there is no increment of voltage when the engine runs the alternator then the connection from the alternator must be checked. Check the output from alternator, check the relay box which contains the charging unit. It can be a failure of the rectification or the stabilising circuit, the unit must be replaced.

Go to web site WWW.HMASERVICE.COM and register your vehicle by VIN #. You'll then have access to shop manuals, wiring diagrams, technical service bulletins, illustrations, etc.
Provided there is no problem with the vehicle's wiring, find out what the charging current is to the battery. I've seen batteries which TEST good, but when under a CHARGE short out internally.
Example: Tested a battery & charging system on a Hyundai Elantra, the battery tested "Healthy" but indicated there was a CHARGING SYSTEM PROBLEM. I checked the battery voltage while the engine was running and found the battery voltage at 14.3 VDC (which was normal). I then used a Digital DC Clamp meter arount the positive (+) battery cable & found the battery was charging at 70 Amps!.. it was supposidly already fully charged (should have only been taking 4 to 6 amps when fully charged).

Best guess without looking/diagnosing the vehicle myself

Maybe this will help.

The instructions for installing a new alternator usually read to fully charge the battery (12.3 - 12.8 volt range). Otherwise, the alternator will be damaged when it initializes. I have seen some extreme damage result from installing a new alternator with a low-charge battery. The torque required to turn an alternator when damaged in this scenario is unbelieveable!
