slow cranking at start

Well it's been along time, but I would appreciate some thoughts on this one. I replaced the glow plugs, relay, batteries are fine, alternator is fine. Could it be the starter causing condition where it sound like batteries are low? Thanks Jcab

Sounds like the starter if you are certain the batteries are good.

maybe get your batteries load checked to make sure they are truly good.

10-4 The starter can definately show those signs. If you remove it the parts stores can bench test it for you. I also agree a load test on the batteries is a good idea but they have to be done independant of each other.

Thanks for the replies. Can autozone load test them, they checked them the first time. And I will check the starter. Jcab

Yes autozone can usually check them for free, and they can also check a starter motor for how well it works. pretty sweet setup.
Same bench can test alternators.
Check all your wires on the way to the starter for a bad connection/short/grounding. that's a fat chance, but if you're running out of options, thats something to look at.

Alot of times autozone and advance want to test the batteries together. Make them test them separately so you can isolate the bad one if there is one.

Possibly, or the good one is hiding the the fact that the other is bad. ie: the good one supports the load whereas the other one couldn't by itself.
