I am not a fan of by passing the safety systems , but there are a few ways to by pass the spool lock solinoids , one way is to remove the solinoid and take a grinder and cut the plunger which sticks out the solinoid off flush and screw it back in , it will no longer engage the spools ----- if you want to save the solinoids then you can go to a hydraulic supply house and get some plugs with the same straight pipe /o ring seal ( also called boss/o ring ) I think it's 3/8's ( #6) -----you can run it with out a plug in it for a short period as no oil will leak out , but the plug keeps the dirt and water from getting into the housing ----------------- you said that when you slammed the door it shut down , that tells me there is a shorted wire or connection problem some where ------------- it can be very hard to locate a short or broken wire , here are a few wiring problems I have seen on that type of machine ----does your machine have a deluxe roof insulation package and have the plastic console over your left shoulder which is for the a/c controls , even if you don't have a/c then sometimes the panel is there on machines , the screws that hold that panel in are too long and very pointy and pierce the wiring harness which runs behind it , I seen where this is very hard to see as the screw leaves a very small hole through the braided covering of the wiring harness but dames the wiring inside the braid -------------another place to look at , which is pretty hard is where the harness goes under the hydrostat , there is a bolt that goes from the bracket under the pump to the pump which always falls out and lets the pump jump around and damages the harness -------another spot is the right controll lever where all the wires from the right side aux controller come out the tube , those wire will hit the bar that crosses the chain case to the controll valve , that right controll head ties into the RPM sensor -------where ever there is a water tight plug in , try pushing each wire into the plug , sometimes the wiring end will slip out the connector and get a bad connection -------- try running the machine with the cab and boom up and locked off and grabbing , pulling and twisting the wiring harness every place you can and see if it will shut down --------------- there comes a time when you might just bring it into a dealer and pay the price
