04 sebring 2.7L alternator will no charge battery.I have changed the battery the alternator and pcm to no avail...I know I should test but I had the parts available from another car so it was no biggie.except the pcm I had it programmed for that car..I looked at the wiring schematics and seen that the pcm controls the regulation through the evr.I dont knw what the problem is All I see is the battery going lower and lower.it dont seem to charge the battery...thanks in advance...

Start your testing procedure by going to your shop information system and reading the "how it works" section for your charging system. This should lead you to a well planned out trail of testing. A wiring diagram will show you how the system works too. You need battery voltage at the B+ terminal on the generator, the PCM (voltage regulator) grounds the field. What is the voltage at the field terminal on the generator? -
Its starts off at 11v and then gradually drops until there is no more current and then it turns off.. its like it dont want to charge no more...Comment

Won't charge
There are 2 different charging systems on 04 sebrings. Need to know if the PCM has 2 connectors (SBEC Controller) or 4 connectors (NGC Controller). Then i can help you. Also the alternators are different, but look alike.Comment

it is a 2 connector..(sbec) correct?
thanksComment

Sorry so late. On SBEC controllers at the 2 wire connector at the alternator you should have an OR/DG wire and a DG wire. The OR/DG wire should always have battery power as long as the car is running. (12volts) The DG wire is the field circuit. (ASD relay powers the OR/DG wire through fuse #25 (20amp) in PDC.) The SBEC C1 connector pin#8 DG wire is the field driver. With a 12 volt test light connected to ground car running you should have voltage all the time at the OR/DG wire. (Fully charged battery) With test light connected to B+ the light should blink on off at the DG wire. (Field driver) Hope this helps.Comment

Ike!!
sorry we got hit with ike here in houston I just got power back at the shop but none at home..
Im going to try that thanks for the help will notify of what i find again thanks...Comment

ok fully charged battery I get 11.50v on dr/or wire then it will cut out.gr wire dont flicker and output of alternator is nothing.basically the alternator is not activating to charge..I would think it is the pcm but I have changed that already. possible alternator?Comment

Update
I have 11.50v from or/dg wire light flickers on and off at dg wire..but no output at b+ wire from alternator..Nothing...Comment

soultion hopes this helps
Battery cable from battery to alternator had short.wouldnt activate field wire..thanks for the help guys..Comment
