  1. Check GAUGE, MPX-B and DOME fuses. Replace as necessary. If fuses are okay, go to next step.
  2. Remove instrument cluster. Check voltage between instrument cluster connector "B" terminals No. 13 (Green/White wire) and No. 22 (White/Black wire). If voltage is 10-14 volts, go to next test listed in INDICATOR TEST INDEX  table. If voltage is not 10-14 volts, repair open circuit in wiring.
