I have a p3000 it starts and runs fine.
But on the display is a big exclamation point that comes up immd. when key is turned on.
We have checked all fluids, check temp sensor and brake fluid sensor and also changed out the display from another truck that works fine. When changed display exclamation point came up immd.
Anny Ideas on what else would cause this.
We did notice that on the hr meter that the hrs would disappear and go to zero but a small zero not a normal siz hr. zero.
Thanks
