Abstract

PURPOSE: To prevent disable start of an engine, by memorizing a drop range of a terminal voltage of a storage battery at the startup of an engine detecting the current terminal voltage to display each state on an operator's seat.
CONSTITUTION: As the life of a storage battery approaches the end of the life, the drop rang of the terminal voltage at the startup of engine increases. Because of this, it is so arranged that the output of IC2 composing a first terminal voltage detection circuit 1-1 reaches the H level, for example, when the terminal voltage falls below 9.0 V, the output of an IC3 reaches the H level, for example, when the terminal voltage falls below 8.0 V and the output of an IC4 reaches the H level, for example, when the terminal voltage falls below 7.0 V and light emitting diodes corresponding to each case are provided as L1: green, L2: orange,L3: red and L4: red to make a display on the operator's seat. The step where L3 is lighted, namely, where one red light come ON indicates that the light of the storage battery exceeds 90%, reaching the end of the life thereof thereby enabling a forecast on whether the storage battery reaches the end of life thereof.
