New Problem!!!! HELP!!!!!!!!!!!!!!!!!!!!

[Bellflower]

Changed the ipc and connector today and installed the new cps. All the codes went away, but now the truck wont start, battery seems weak and the tach jumps like crazy. New batterys or what??????? Also the WTS light does come on, but i hear a clicking under the dash like a relay opening and closeing rapidly while im trying to crank it. Help Please. Im starting to want a Duamax!!!!!J/K

definately sounds like the batteries are weak or bad....if they wont take a charge, id have them tested......

When batteries are low and it won't crank, your tach will jump all over the spectrum. Take these batteries out and have them tested. If they are old and one is bad, get 2 new ones, not one.
If the other battery goes out shortely, you could and will fry your voltage regulator and be buying a new alternator. Don't ask me how I know this ...

duramax??? shame on you!!!!!

Alright, its running after a good charge on the batterys, sitting for a week in 100 degree heat probably drained them good. the new blue cps made it alot quieter I think. Well no duramax for now, the powerstoke is alive again

Have those batteries tested! If one is bad, they won't take a full charge but your voltage regulator will keep trying untill it smokes itself!
Did you seperate the batteries and give them a good 20 hours each to charge seperately? If not, you didn't charge them right.
