G.Voltage Drop Testing
Test the voltage drops caused by the switch, cable,
solenoid or connector. Any abnormal voltage drop
generally results from an additional resistance. The
resistance will restrict the currents upon the start of the
engine, leading to the reduction of the load voltage of
the battery and the slow-down of the start of the engine.
1.Cut off the ignition system so as to disable the
start of the automobile.
Cut off the main ignition coil, shunt coil, cam and starting
sensor so as to cut off the ignition system. Operate by
reference to the automotive manual.
