CHASSIS ELECTRICAL
FUEL GAUGE SIMPLE CHECK
Connect a test light to the harness con-
nector.
Place the ignition switch in the ON posi-
tion.
Check the test light and gauge conditions.
TACHOMETER CHECK
(1) insert paper clip into the engine revolution speed detection
terminal provided in the engine compartment, and connect
the engine tachometer to the inserted paper clip.
Caution
As the tachometer is negative grounded, do not con-
nect battery conversely to prevent damaging transis-
tor and diode.
NOTE
For tachometer inspection, use of a fluxmeter-type engine
tachometer is recommended. (Because a fluxmeter only
needs to be clipped to the high tension cable.)
(2) Connect the engine tachometer and compare the engine
tachometer and tachometer readings. Replace tachometer
if difference is excessive.
Standard value:
1,000 f 100 rpm
3,000 + 150 rpm
5,000 f 250 rpm
6,000 f 300 rpm
Caution
The engine speed signal output from the engine is
one-third of the actual speed. When the engine speed
is measured, make sure that the engine tachometer
is placed in the 2-cylinder range. (The real speed is
indicated.)
