Voltmeter Inaccurate

  1. Start engine and observe voltmeter. If voltmeter does not operate, go to next step. If voltmeter needle is at mid-scale in NORMAL band, voltmeter is okay. If voltmeter needle is below or above mid-scale, check battery and charging system and repair or replace as necessary. If voltmeter needle is below or above mid-scale and battery and charging system are okay, replace voltmeter and retest system. See GAUGES  under REMOVAL & INSTALLATION.
    NOTE: Some models may have a calibrated 190 ohm resistor in printed circuit between battery input and gauge.
  2. Turn ignition switch off. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Measure resistance of printed circuit between voltmeter gauge clips and instrument cluster connector C286, terminal No 13 and instrument cluster connector C287, terminal No. 2. See Figure and Figure .
  3. If all resistances are less than 5 ohms (180-200 ohms for circuit with resistor), replace voltmeter. See GAUGES  under REMOVAL & INSTALLATION. If any resistance is more than 5 ohms (180-200 ohms for circuit with resistor), replace instrument cluster printed circuit. See PRINTED CIRCUIT  under REMOVAL & INSTALLATION.
