MEMO ELECTRICAL 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 box (6). 1. Terminal "1" of DC-DC converter (for memory backup of stereo) 2. Terminal "B" of starter switch 3. Hour meter 4. Engine controller 5. Fuel feeder pump switch 6. Terminal "6" of wiper motor 7. Terminal "13" of wiper controller 8.
Terminal "CN6-11" of instrument panel 9. Terminal "CN9-6" of air conditioner panel 10. Cabin light When the starter switch (5) is in the "ON or START" positions, the current flows from the battery (1) fusible link (3) fuse box (6) "B" terminal of starter switch (5) "BR" terminal of starter switch (5) "BR" terminal of battery relay (2) 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).
