Exclamation WON'T START, TURNS SLOW, NEW STARTER & BATT'S

I shut the truck off at night, then the next morning it would not start. It was about 10 deg F above 0.
Engine turned over real slow, took off the starter and had it checked, they said it was shot. Got a new Starter.
Still turned to slow to start, replaced batteries.
Still turns slow, like something is dragging.
Any idea's Tech's?
Thanks

Make sure battery connections are clean and good. Best batteries in the world wont help if the cables are beat.

Check for a draw, plus you should use a 10W30 Rotella.

Make sure your batts are 850 CCA a piece.

i would check and see what your volts are at the starter first and if its not above 12.4 you have a draw if it is and it still turns over slow i would check your starter realy and jump 12.0v to the starter after that and it turns fater then thats your problem

i am a ford diesel tech so if you have any other qustion fell free to ask

what kind of oil are you running in your truck?

Also, just shut everything off and pull the key out, check voltage on the battery, if anything is over 0.7V then you have a draw.

check your front accessories (a/c compressor, alternator, p/s pump ect) one may be locked up and causing major drag on the starter. just a shot

Isn't there some way to make the codes scroll accross the dash?
I've checked all I can on this using the help from the posters, but still not starting.
I don't have any way to check voltage......and I am kind of a beginner at a lot of this.
The truck was running good, then when I tried to start it on a cold morning, it turned over real slow. New Starter and batteries since then, but still turninig over slow. I checked to see if it looked like the a/c compressor, alt, and etc was dragging, but they look ok. Thanks for all the help!!
