Tachometer: Testing and Inspection
1.
Connect a tune-up test
tachometer and start the engine.
2.
Compare the tester and
tachometer indications.
If the difference is excessive, replace the
tachometer.
CAUTION: 1.
Reversing the connections of the
tachometer will damage the transistor and diodes inside.
2.
When removing or installing the
tachometer, be careful not to drop it or subject it to severe shock.
