Electrical Continuity

  1. Check fuel tank for adequate fuel supply. Check for leaks at all lines and fittings. Disconnect connector to fuel pump just forward of fuel tank. Connect a voltmeter to body wiring harness connector.
  2. Turn ignition "ON". Battery voltage should be present, voltage should return to zero after approximately 1 second. Turn ignition switch momentarily to "START". Voltage should be approximately 8 volts while cranking. If voltage is not within specifications, check electrical system.
