Weak Starting: new batteries turn over slow?

I've got a 97 f250 and am having a little starting trouble. I have 2 brand new batteries a brand new GPR and all 8 new glow plugs. It seems to start fine the only problem is it takes many cranks to start. When I first turn the key to start it, it cranks very slow about 2 times then sounds like it gets power all the sudden and turns over better. It sounds almost like the batteries are about dead when really they are not. I have cleaned all my battery cables and the ground connection on each, but it still cranks weak at first and then builds up power as i continues to crank. Not sure what the problem is i attached a pic of my voltage when i have my key turned on not sure if it should be higher or what please someone let me know. Thanks

Have your starter tested or replace it.

Also check your cable ends. If you have a bad connection the longer that you apply the voltage to the starter they will burn off the oxidation and give you a better connection.

That is about where my voltage is at with the key in the ON position. I wouldn't worry there. It sounds like a starter isn't spinning fast enough though...

You will be amazed what a new starter will do for the truck...

Re: Weak Starting: new batteries turn over slow?

call diesel equipment in potterville mi. buy their hi torque starter. live happily ever after. lol. Those hi torques are stupid. Sounds like a mini 7.3 turning it over at 3x normal speed. They always fire. Thats my next investment, as i have the same problem. All my friends and brother have bought then and are happy as hell.

Re: Weak Starting: new batteries turn over slow?

Alright thanks I'll look into that. What about a regular starter though. Do I need to buy one from Ford or International in order to get this monster to turn over correctly? Or would one from the local auto parts store (aka NAPA) be sufficent?

You can get one from a local parts store/shop. It's just your personal preference. But do get one for a 99-03 7.3. It is a gear reduction starter and turns over much better that the 94-97 starter. Costs about the same. You will be very happy with one of these.

Just get one from O'rielly's or the like... Lifetime warranty and when it fails, there is usually a store within a fair distance...

Re: Weak Starting: new batteries turn over slow?

Will the starter from a 99-03 bolt right up with ease. Or does it have to be modified in order to fit onto my 97 ??
