What fuses feed these circuits on the Nissan Micra wiring diagram?

The gauge/warning lamp circuits are fed by FUSE-IG (shown at three points on the top diagram), while the wiper, washer, radio, cigarette lighter, heater relay and blower motor circuits are fed by FUSE-ACC.

What positions does the Micra wiper switch have?

The wiper & washer switch table shows OFF, INT, LO, and HI positions plus a washer position; an intermittent wiper amplifier with a 6-pin connector (pins 1-6) controls the INT function.

What positions does the heater fan switch have?

The fan switch table shows OFF, LO, M1, M2, and HI positions, working with the heater relay, resistor, and blower motor. One switch position row is marked 'Not used'.

What is on the check connector shown in this diagram?

The check connector detail shows terminal 1 (IGN.), terminal 7 (automatic choke), terminal 11 (throttle opener), and terminal 12 (body ground), with an arrow indicating the check terminal.

What resistor value is used with the tachometer circuit?

A 2.2 kΩ resistor is shown at the right side of the top circuit near the tachometer.

This document is a scanned page of a factory-style electrical wiring diagram, uploaded as applying to a 1990 Nissan Micra. The page contains three horizontal wiring schematics. The top circuit covers warning and gauge systems: charge warning lamp, power steering oil pressure switch, thermo switch, radiator fan motor, thermal transmitter, fuel tank gauge unit, temperature/fuel gauges (V/R), parking brake and brake fluid level switches, back-up lamps, inhibitor switch (A/T), oil pressure switch and warning lamp, seat belt timer/switch/warning lamp, chime, steering lock switch, door switch, rear defogger and switch, tachometer, and a 2.2 kΩ resistor. The middle circuit shows illumination and interior lighting: illumination control unit, meter, radio, heater control and A/T indicator illumination, stop lamps (LH, RH, high-mounted), room lamp, door switches, luggage compartment lamp, and a check connector detail showing IGN, body ground, automatic choke, and throttle opener terminals (positions 1, 7, 11, 12). The bottom circuit covers accessory items fed by FUSE-ACC: front wiper/washer switch and motors (OFF/INT/LO/HI), intermittent wiper amplifier (6-pin), rear wiper and washer switch/motor, radio, cigarette lighter, heater relay, blower motor, resistor, and fan switch (OFF/LO/M1/M2/HI). Circled letters (A, B, D, F, H, I, M, R, Y) mark inter-page circuit connections; grounds are marked 55M.
