i put a new timing chain and water pump on my truck when to start it up and it started perfectly then i noticed it wasn't charging and i went back over what i did and everything is hooked up right and i cleaned and the grounds all the wire ends i tried switching battery's i had the alternator tested and it passed i have power threw all the wires it just don't seem like its getting to the battery cause the battery is at 12.2 volts with it running or not all the fuses are good what else could it be???

 

check the small wires going to the alternator. one or more should have 12v on it to activate the field wiinding or something? see if you have a loose or broken wire.

edit - also check all your fuses in the PDC and the end of dash, especially those big ones.

you did disconnect your battery when doing your work - right ?

 

i was going to ask the same thing.

 

Maybe the voltage regulator in the PCM took a dump.
xray99 had problems with his voltage regulator and bypassed it and got it to work, so that would be worth testing.
You need to go over the connectors with contact cleaner and check all the fuses first though.
When the voltage regulator is messed up then the alternator won't charge the battery.

 

yea i always disconnect the battery when i work on it and all the fuses are good inside and out i tested the wires and cleaned all the grounds everything seems fine is there anyway of fixing it if it is the pcm or can i get one from a junk yard or should i just buy a new one?

 

oh and i just bought a new alternator and there is no difference

 

This is the thread that I was talking about.

i read trough that and i almost positive it has to be my pcm i have nothing else it could be cause the alternator is producing volts its just not getting to the battery so I'm going to try a used computer at a local junk yard and see if it does the trick if not it going to be heading to a dealership and they can figure it out

 

If your alternator is putting out more than battery voltage, (should see between 13 and 15 volts right at the alternator) the alternator, and voltage regulator are fine. The alternator feeds power back to the battery via the HUGE fuse in the power distribution block, one would think, if that fuse were blown, NOTHING would work..... so, trace the feed wire from the alt, and work your way back to the battery, and see where you lose power at, and then fix the open circuit.
