Portable machine with machine diagnosis indicator circuit

A combination comprising:

• a) a portable machine having a frame and an engine supported by the frame, the engine having a power source and a means for cutting off power to the engine;
• b) a machine diagnosis circuit comprised of at least one protective switch connected in series with the engine power source and said means for cutting off power to the engine, said circuit also including a first diagnosis indicator across the at least one protective switch, the first diagnosis indicator comprising a first LED pair and a first resistor, the first LED pair adapted to be illuminated when the associated at least one protective switch is opened, said circuit also including at least one non-protective switch and a second diagnosis indicator comprising a second LED pair and a second resistor, the second diagnosis indicator is wired through the at least one non-protective switch so that the second LED pair is illuminated when the at least one non-protective switch is closed, the at least one protective switch and the at least one non-protective switch being connected to a sensing means for measuring the value of a machine operating parameter associated with the at least one protective and the at least one non-protective switch;
• and
• c) means for indicating the specific location of an engine fault condition, said means for indicating the specific location of an engine fault condition overlaying the first and second diagnosis indicators.
