Im new to the bobcat world and have a couple of questions:<ul> <li data-xf-list-type="ul">Perkins 1004-40T w/stanadyne DB4 pump. The shutoff solenoid appears to run off vacuum, but the lever moves up/down freely by hand. Is that normal? Which position allows fuel to flow?</li> <li data-xf-list-type="ul">On the orange wire going to the switch for the loader valve (and a couple of places in the engine bay) I have continuity to ground. That seems odd to me, Ive never heard of a company using orange for ground? Is that correct?</li> <li data-xf-list-type="ul">Where are ya'll getting used/salvage parts from? I have a couple of pieces I need to replace and I think salvage is going to be the best route</li> <li data-xf-list-type="ul">How do I unplug the BICS computer? Stupid question, but I cant find a tab to push on the wiring connector or anything. I need to run some testing on the wiring there</li> <li data-xf-list-type="ul">Im getting 180-200 psi on all 4 cylinders which I assume is why I cant get the engine to pop off. Anyone know what compression should be? I cant find a spec for it online</li> </ul>Appreciate any help.</blockquote>
