Shift-up Indicator
Operation
Component Locations
The shift-up indicator is installed on cars with manual transmission only. The light in the instrument cluster lights up indicating to the driver when to shift up. The light will stay off if the
car is in fifth gear, if the engine temperature is below 95°F
(35°C), or if the throttle is in the rest position. A time delay
function of 1.7 seconds prevents the light from flashing and
causing irritation. This time delay function is incorporated in
the shift-up indicator relay (270). 1989 and later models have
shift-up incorporated into the LH control unit.
NOTE
For shift-up wiring diagrams on 1989 and later models, see
Combined Instruments elsewhere in this section.

1. Check the fuses with the key in the run position.
2. Check for voltage at the shift-up relay (270) terminal G
and terminal 15. The car should be in first gear and the
engine temperature cold (less than 95°F).
3. Check the shift-up lamp (47K) in the instrument cluster.

Operation
4. On 1992 convertible models, check the start interlock relay 423 for the burglar alarm, located under the rear seat.
For information on removing and repairing the starter see
331 Starter. For more information on replacing and adjusting
the neutral safety switch on automatics, see 444 Automatic
Transmission Controls.
WARNING
Batteries generate explosive gasses. Keep sparks and open
flame away. Do not smoke.

CAUTION
• Do not disconnect the battery when the engine is running.
The altemator could be destroyed.
• Always disconnect the negative (-) battery cable first when
servicing the starter. Reconnect the negative (-) battery cable
last.
Fault Tracing
1. Check for battery voltage at terminal 30 of the starter.
2. Check for battery voltage at terminal 50 of the starter
when the key is in the start (crank) position. If no voltage
is present, check the ignition switch and ignition relay.
3. Check for continuity between the engine block and battery negative (-) terminal.
