- ELECTRIC SUPPLY SYSTEM
- The electric power circuit supplies electric current to each electric component. It consists of a battery, battery relay, starter switch, circuit breaker, fusible link and fuse box.
- The negative terminal of the battery is grounded to the vehicle body.
- Even when the starter switch (5) is in the “OFF” position, electric current is supplied to the following components through battery (1) → fusible link (3) → fuse (6).
- 1. Cabin light, fuel pump switch, No. 1 terminal of DC-DC converter (backup for car stereo memory)
- 2. “B” terminal of starter switch and No. 22 terminal of air conditioner control panel.
- 3. No. 17 terminal of instrument panel (backup for instrument panel).
- 4. Power terminal “B” of engine stop motor.
- When the starter switch (5) is in the preheat, on and start positions, the current flows from the battery (1) → fusible link (3) → fuse (6) → starter switch (5) “B” terminal/starter switch (5) “BR” terminal → battery relay (2) “BR” terminal which activates the coil of the battery relay and the electric supply system is energized.
- When the battery relay’s contacts are connected, all electric devices can be operated.
- While the engine is not running, the electric power for all electric devices are supplied by the battery. Once the engine is started the power is supplied from the alternator (7).
