WARNING: This page is about a different car, the 1997 Isuzu Trooper. However, it is still accessible from the selected car via links, so may be relevant.
- Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Remove speedometer from instrument cluster. Using an ohmmeter set to the 1000-ohm scale, measure resistance of tachometer. SeeFig 1 . Replace tachometer if resistance is not as specified.
- Ensure instrument cluster tachometer readings closely match those of an external tachometer. See TACHOMETER VARIATION SPECIFICATIONS .
