won,t turn over

And nowhere in this story did you charge the battery.....or jump it ???
Really ???

Battery tests can lie.

A healthy battery is critical in getting a diesel started.

And the battery is the first thing you should suspect when the solenoid just clicks.

yes the batterys was put on charge

Probably dead batteries. How old are they?

How about a bad ground

Could it possibly have a 2nd relay? Our V-10 does, it's not shown in any diagrams, we had the same symptoms you are having, but I don't know if any other engines have a 2nd one or not.

99.9% of the time this is caused by a bad connection somewhere, be that at the battery, starter, or chassis ground. You need to pull the connections apart and actually clean them. A visual inspection will not root out the problems.

Bad connections would be my first guess.

Sometimes, a vehicle Mfg will slip in a catastrophic fuse into the positive battery cable. These can be difficult to find as they are jacketed with the same cable insulation jacket.

The best diagnostic test is to see what voltage and amperage are present at the starter when called upon to turn. This measurement will discover any number of issues.

How old are the batteries?

Jump power on the solenoid on the passenger inner fender. This will prove that the batteries and starter are good, and that the 'start' circuit from the ignition switch to the solenoid is bad.
You could have an issue with the ignition tumbler itself or the wiring to the solenoid.
I recall there being a passive theft device somewhere under the dash that interrupts the start circuit. It happened on a '95 psd we had. It failed, don't know how it worked. We would place the key in the 'on' position then jump the solenoid under the hood to get home. I remember it being a black box a little larger than a billfold. It was located near the steering column.

3rd vote in. Disassemble. Clean with emery cloth until shinny.
