Low readings. This type of engine will continue to run as long as it has fuel and air and heat, so logically in order to stop the engine from running one must remove one of those three things. Typical wiring diagrams for the popular Tattletale® annunciators and magnetic switches are linked to this page as pdf files for downloading. There is no way to “switch off” a diesel engine, because “switch” implies electricity and a diesel engine requires no electricity. I believe it's something on the engine that shuts it down to prevent damage like low oil pressure, high water temp, low water level, high oil pressure, etc. Diesel engines are one type and gas turbine engines are another. There are different kinds of internal combustion engines. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogeneous air-fuel mixture. A fundamental theory of how heat engines work, known as Carnot's rule, tells us that the efficiency of an engine depends o… It is run by an old Murphy Diesel out of an old Northwest dragline. The engine should be switched off or the oil filter could burst. This signal comes from the windings in the alternator before it’s rectified to DC and regulated to the system charge voltage. Old? While the engine is running if the water temp gets to high the water temp switch sends a ground signal to the murphy witch trips the murphy switch and kills power to your fuel solenoid at the injection pump stopping fuel from going to injectors and killing your engine. The L150 Series Level Swichgage® instrument is a combination liquid level gage and low-limit switch; each unit includes (1) a chamber with pivotal float, (2) an indicating dial with pointer and (3) a low-level contact. The fuel injection pump pressurizes fuel into a delivery tube. Not all alternators come with this terminal. Typically this panel will control the ignition coil, an inline fuel valve or a push/pull solenoid for shutdown. It allows for Swichgage and/or N.C. contacts to be wired "Closed Loop" (in series). The WAI Panel Series can be wired for delay on both start and stop. ¾ If no voltage was on 4, check Murphy Relay. Low current, high torque, solid-state switching and an electronic clutch make it ideal for all automatic and semiautomatic engine systems.
