Thanks for the replies. For clarification, I gave the truck to my son 2 years ago, and the last two years of that trucks life have been the absolute hardest years of it's life. He lives on our farm in his own trailer and is a full time college student, so we are still helping with the big bills.
We replaced one battery cable end that was bad, the cables had been converted from side post to top post by the original owner (I bought it used a couple years old).
In defense of my mechanic, he did show us how he checked the Glow Plugs and found ones that weren't functioning, but I too was skeptical that had anything to do with the rate at which the motor turns over. And after spending $380 for the glow plug repair I thought we were good, my son said it was OK.
Then we traded trucks for a day, and I realized my old truck is not OK, and I don't like that my 22 year boy said it was OK and I don't like that my home town trusted mechanic may have lined his pockets with a repair that should have been secondary to what I brought it in for.
I'm at an age where I don't really enjoy wrenching under trucks like I used to. But I will throw a little more $$$ at it and replace the starter with an new, not reman, starter.
All the best, Hans
