In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.\n\nPOWER SOURCE (Current Flow Chart)\n\nThe chart below shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit Breaker, Fuse, etc.) and other parts.\n\nThe next page and following pages show the parts to which each electrical source outputs current.\n\n[Chart section:]\nBattery - FL MAIN 2.0L\n  100A AM2 ④\n  30A AM2 ①\n  15 Headlight Cleaner Relay M2\n  15 Headlight Cleaner Relay M8\n2 Starter S3\n\n3.5 Ignition Coil and Igniter I2 - 10A HTR-MIR ④\n5 Injector No. 1 I3 - 10A A/C ④\n5 Injector No. 2 I4 - 15A ENGINE ①\n5 Injector No. 3 I5 - 15A ECU-IG\n5 Injector No. 4 I6\n\nPage Nos. of Related Systems: 32 32 32 10 32 25 28 10 12 12 32 32 12 12 6 30 10 5\n\nParts:\nCode or Location\n\nA/C Hot Up, ISV\nA/C Amplifier\nA/C SW\nA/C SW Light\nA/C Pressure SW\nADD Control Relay\nAuto Antenna Control Relay\nA/T Indicator Light\nBack-Up Light SW\nBack-Up Light\nBlower Motor\nBlower Resistor\nBack-Up Light LH\nBack-Up Light RH\nCigarette Lighter\nCigarette Lighter Light\nCircuit Opening Relay\n\nLocation CB or Fuse: A1 A8 A9 A10 A11 A12 O9 B1 B3 B4 B5 R5 R6 C2 C8 C8 C9\n\n10A ENGINE\n20A WIPER\n10A TURN\n10A [partial text visible]\n\nPOWER SOURCE\n\n[Diagram section contains labels:]\nI-20B FL MAIN\nBATTERY\n80A MAIN\nI-2A AM2\n18A HAZ-RADIO\nINJECTOR RELAY\nSTARTER RELAY\nI-3 B.A DOME\nDAILILIGHT CONTROL\nI.B IGNITION SW\n10A TAIL\n20A DEFOGR\n15A HAZ CIG\n\n* The system shown here is an EXAMPLE ONLY.
