CHECKING POWER TRANSISTOR N14RCGA

(1) Detach the power transistor connector.



(2) Check to be sure that electricity flows when a voltage of 1.5 V is applied between power transistor terminals (1)-(2).



(3) Check whether or not electricity flows when a voltage of 1.5 V is applied between power transistor terminals (3)-(2).


Terminal (1) voltage Between terminals (3) - (2)

When applied (solid line) Electricity flows

When discontinued (broken line) No electricity flows
