The otherday we put 2 week batteries in the truck/ we only saw the main power and ground not the small wires that are on each of them. we hooked the main and ground up and turned the power and start switches, nothing, no low air buzzer nothing. So we went to the starter and jumped it at the selonoid. truck turned over but batteries were to week. Now I put 2 new big batteries in. hooked the wires up and saw the small wire on the main hotwire and the small on the ground wire. Hooked them up hot on hot ground on ground. flipped the top power switch, lights came on, blower worked dash items on. flipped the start button to on low air buzzer sounding, flipped it to start, nothing, would not turn motor over, no other sounds. Went to the starter to jump it off, and still nothing, would not jump off selonoid. could not get anything to turn motor over. Any help you can give? Looked through manuals says if this happens consult supervisor.
If I could get some help on what to test or what it could be, I be greatful.
Thanks

it is. I found something in the TM. It shows a pic of the main power feed going to the starter from the battery with a small wire with it, but in the pic the small wire branches off and goes to a ground post on the battery instead of a hot post. could this be a ground wire for the electrical, including the starter?

Ive had 250 cummins for 35 years, they can be hard to turn over. They need 4 good big batterys to really crank right. sometimes you can get away with 2 ,but only if its warm (70+)out. Put 4 good batterys in it (truck batterys are ok i dont like the 6tl's ,too expensive) check and clean all your grounds. On one of my trucks i had to run a separate ground from the starter to the batterys...i just couldnt get it to crank strong...then it was good.
