Upon placing the RUN/STOP switch in the “RUN” position, you should hear a
“click” near the engine. This is the FUEL SOLENOID engaging. It should stay
engaged. You should also see all 5 ENGINE WARNING LIGHTS come on for
about 5 seconds and then go off. Then, operate the START button. ENGINE
WARNING LIGHTS WILL COME BACK on then off again. All gauges should be
in the NORMAL operating ranges. About 30 seconds after starting the engine,
the “inihibit” circuit which prevents ENGINE SHUTDOWN will turn-off. Engine
should remain running.
