Test F: Warning Indicator Flickers Or Operates Intermittently

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect all generator, power distribution and battery connections for looseness, corrosion, and loose or bent terminals. If all connections are okay, go to next step. If a problem exists, repair as necessary.
  2. Start engine and let idle. Inspect central junction box fuse No. 45 (10-amp) for looseness. Wiggle fuse connection and note warning indicator. If warning indicator does not flicker, go to next step. If warning indicator flickers, repair loose fuse connection as necessary.
  3. Turn ignition off. Using a fused (15-amp) jumper wire connected to positive battery terminal, backprobe generator harness connector terminal No. "A" (Orange/Light Blue wire). See Figure. Start engine and let idle. Observe warning indicator. If warning indicator flickers, replace generator and test system operation. If warning indicator does not flicker, repair loose connections in circuit between generator and Gray fusible link "C". See WIRING DIAGRAMS .
