Abstract
PURPOSE: To eliminate the need for the particular preparation of a tester when testing a circuit of a location to be checked, by providing circuit device itself of an electric rolling stock, such as, a battery fork lift, etc. with a tester.
CONSTITUTION: Each logic unit, the logic portions of a driving device of an electric rolling stock, is installed onto a logic print substrate 21 by using circuit parts 22... while luminous diodes ED1WED11, UL, LL disposed to check point portions are mounted with their drive circuits. An opaque or translucent mask 23 displaying a circuit diagram, which has a circuit content of the electric rolling stock of a location to be checked, is covered, check point portions (These are shown in round marks in dotted lines) are drilled or made to be transparent, and whether or not a circuit of the location to be checked is normal can be discriminated by the flickering display of said luminous diodes.
