  1. If LED is bad, replace LED and retest. If LED is okay, disconnect connector "B". Check resistance between connector "B" terminal No. 23 and ground. If continuity does not exist, repair open circuit between connector "B" terminal No. 23 and ground. If continuity exists, go to next step.
  2. Turn ignition on. Check voltage between connector "B" terminalNo. 1 (+) and connector "B" terminal No. 23 (-). If battery voltage exists, replace power source unit and retest. If battery voltage does not exist, repair open circuit between GAUGE fuse and connector "B" terminal No. 1.
