Test B: Warning Indicator Is On With Engine Running, System Is Not Charging (3.0L DURATEC)
WARNING: This page is about a different car, the 2004 Ford Escape, 2003 Ford Escape, and 2002 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
- Measure voltage between ground and generator B+ terminal (Yellow/White wire). See Fig 1. If battery voltage is present, go to next step. If battery voltage is not present, repair circuit between generator and battery.
- Turn ignition switch to LOCK position. Disconnect generator 3-pin harness connector. Measure voltage between ground and generator connector harness terminal No. 3 (Black/Yellow wire). See Fig 2. If battery voltage is present, go to next step. If battery voltage is not present, repair circuit between generator and battery.
- Turn ignition switch to RUN position. Measure voltage between ground and generator harness connector terminal No. 1 (Light Green/Red wire). If battery voltage is present, go to next step. If battery voltage is not present, repair Light Green/Red wire between generator and instrument cluster. See WIRING DIAGRAMS .
- Start engine and run at 2000 RPM. Measure voltage between positive battery terminal and generator terminal B+ (Yellow/White wire). See Fig 1. If voltage is less than 0.5 volt, replace generator. If voltage is 0.5 volt or more, repair Yellow/White wire between generator and battery.
