1975 Datsun 280z FSM - Spooled up Racing

RESISTOR (For
illumination control)
This resistor controls the brightness
of illumination for each meter, clock,
radio and heater control; it is a variable
resistor and its value can be controlled
by a knob.
REMOVAL AND
INSTALLATION
1. Remove knob of switch; it should
come off easily.
2. Remove three screws retaining
resistor bracket to instrument panel
from behind of instrument panel.
3. Disconnect lead wire to resistor at
a connector behind instrument harness.
Switch assembly can then be taken
out from behind instrument panel.
4. Remove nut retaining resistor to
bracket then resistor can be taken out.
Body Electrical System
5. Installation is in the reverse sequence
of removal.
INSPECTION
Test continuity and resistance between
two lead wires with ohmmeter.
When switch is in OFF position,
continuity must not exist. In ON
position the resistance varies from
about 10 £2 to 012 depending on the
setting of the knob.
FLASHER UNIT
REPLACEMENT
Two flasher units are installed at
L.H. side trim under instrument panel.
One is for turn signal and the other is
for hazard. They are different from
each other.
1. Disconnect battery ground cable.
2. Disconnect lead wires at connector.
3. Remove screw retaining flasher
unit to inner side trim.
4. Install new flasher unit in the
reverse sequence of removal.
