99 Vp44 truck cranks slow and then quickly sounds like a very weak battery condition as far as the starter sound. It sounds like the starter is not giving enough power to turn over, then it barely starts. When it starts, it runs great(like usual). I even had someone else test my batteries and they are both new. I checked starter wiring, and it is all clean and tight. Any suggestions? Starter? it's about 3 years old.Thanks ahead of time,Will

I just replaced mine for the same things you are experiencing. The starter was about 4.5 years old and under a lifetime warranty. It could be a bad wire to the starter and you are not getting enough voltage to run it properly. but I will defer to the more electrically knowledgeable to help with that. My batteries are also less than 6 months old.

Might be time to pull the starter and check the brushes and contacts. Both can be purchased at LarryB's and rebuilt yourself...
