TACHOMETER INSPECTION
(I) 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
‘4
connect battery conversely to prevent damaging tran-
sistor 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 flO0 rpm
3,000 f 150 rpm
5,000 f250 rpm
6,000 rfr300 rpm
Caution
The engine speed signal output from the DOHC 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.)
