Abstract:
A school bus systems tester for performing safety checks on a school bus having illumination and signal lighting circuits, the systems tester comprising:electrical circuitry connectable to and selectively energizing and annunciating illumination and signalling lighting circuits of the school bus;said electrical circuitry having subcircuits, each serving a selected illumination and signalling lighting circuit;each said subcircuit having a switch for selectively controlling its respective subcircuit;an annunciator selected from a lamp and an audible element responsive to successful energization of each said subcircuit;a housing enclosing said electrical circuitry; anda plurality of dissimilar modular wiring connectors each having a plurality of conductors, each individual conductor corresponding to one illumination and signalling function of the bus, individual conductors for each like illumination and signalling function of each said modular wiring connector being connected in parallel by said electrical circuitry to a predetermined said subcircuit, whereby like functions are energized and tested on buses having different modular wiring connectors by a designated one said subcircuit.
