Circuit-System circuit diagram

System summarization
· The current goes through IG power supply relay when ignition switch is turned on, and R14 electromagnetic
coil is grounded; electromagnetic coil will generate magnetic field, and contacts of relay R14 will be closed;
current of battery goes to fuse F/L4 through main fuse F/L0, goes to the pin No. 10 of combined meter through
the contact of relay R14, goes to pin No. 6 of combined meter and excitation bind posting of alternator through
charging indicator, goes to the excitation of alternator excitation winding.
· The alternator begins to supply electricity through 2 circuits after it is run.
One circuit: internal supply to voltage regulator and to alternator excitation winding through the voltage
regulator to control the electricity capacity generated by alternator.
The second circuit: goes to battery through F/L0 to charge the battery with constant voltage and supply
electricity to power consuming devices. Now, the voltage on pins No.10 and No. 6 of combined meters are
supplied by alternator, so they are at the same potential and charging indicator will be off.
