Test F: Warning Indicator Flickers Or Is Intermittent

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, and 2004 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.

  1. Check For Loose Connections

    Inspect all generator, power distribution and battery connections for looseness, corrosion, and loose or bent terminals. Are all connections clean and tight? If yes, go to next step. If no, repair as necessary. Test the system for normal operation.

  2. Check Fuse Connections

    Start engine and let idle. Inspect central junction box fuse No. 45 (10-amp) for looseness. Wiggle fuse connection and note warning indicator. Does the charging system warning indicator flicker? If yes, repair loose fuse connection as necessary. Test the system for normal operation. If no, go to next step.

  3. Check "A" Circuit (Orange/Light Blue Wire) Connections

    Turn ignition off. Using a fused jumper wire (15-amp) connected to positive battery terminal, backprobe generator harness connector terminal No. 3 (Orange/Light Blue wire). See Figure. Start engine and let idle. Observe warning indicator. Does the charging system warning indicator flicker? If yes, install a new generator. See GENERATOR  under REMOVAL & INSTALLATION. Test the system for normal operation. If no, repair loose connections in circuit between generator and Gray fusible link. See WIRING DIAGRAMS . Test the system for normal operation.
