I am working on a 2007 Dodge Caliber 2.0. The alternator was making very loud noises and it killed the battery. I replaced both but it's still not charging. What would be my next step?

Ck the battery, ground & ck that pos wire from the batt to the alternator. Ck all connections.

there are fusible links that will melt,like a fuse,find all of them and replace the bad ones,its on the secondary wire to the positive side of the battery

The signal to the alternator is controlled by the ECM/PCM, so the best thing to do is check all connections to the alternator and battery to make certain that they are clean and tight and have the vehicle scanned for fault codes.
There is one larger red w/grey wire to the alternator, that should have power from the battery, if it does not, then the fusible link to that wire has blown. If there is power to that wire, then the problem may either be in the alternator itself or the PCM.
If that is the case, you will need to hook up a scanner to it, to see what the PCM is saying that the charging system voltage is.

have alternator rechecked new doesnt mean free from defects---check wiring and connectors-have battery tested may not be taking charge [damaged ] and check fusible link if above are good

My dodge caliber 2007, makes a really loud noise what is it??? 3 mechanics 7 3 wrong diagnoses later, and Dodge Manufacture telling me it is not something that is a common problem, i found it.. first it was the bearing on the Ac Compressor (WRONG), then it was the idler pulley bearing (wrong), then it was the water pump bearing (wrong). It was the alternator bearing (YEP) 3 mechanics, 2 dodge corporate call, and finally self perseverance finally some one got it right... ME i ho

when you hear a clicking sound it means your battery voltage is too low The battery posts and clamps need to be cleaned and put back together. Did you leave lights on or something to kill the battery? Or is the battery not charging? You may need a new battery and a new voltage regulator. Is the belt tight? Is the alternator producing a voltage or is it time to get it serviced or replaced? These are rhetorical questions of course.

1. Disconnect and isolate negative battery cable at battery. 2. Remove the right front wheel. 3. Remove the underbody air dam.



4. Remove the accessory drive splash shield.



5. Remove the accessory drive idler pulley.



6. Loosen the lower mounting bolt.



7. Loosen the A/C compressor and relocate, pull down and to outboard side of vehicle to make room to remove generator.



8. Unplug field circuit from generator.



9. Remove the B+ terminal nut and wire.



10. Remove the upper mounting bolt. 11. Remove the generator lower mounting bolt.



12. Relocate the battery terminal (1) to the other side of the A/C line (2) for removal of the generator.



13. Rotate generator pulley down.

have you replaced the belts/pulleys

Try having the linkage greased on your next oil change hope this helped

its your alternator my caliber did the same thing and now its out completely...
