"Can you explain the post Nd the case? I did not under stand that part"
Post I meant the terminal with nut where the big cable attaches. From there to the case/frame/ground there should be continuity and very low resistance
"When i check the post and the brushes i get .7 ohms on 2 and open on the case."

If theres no continuity IE an open circuit from the commutator segments to the steel shaft THATS GOOD THE ARMATURE ISNT SHORTED
Some cheaper ohm meters arent real accurate at low ohms readings

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
