Test A: Charging System Warning Indicator Is On With Engine Running (3.0L)
WARNING: This page is about a different car, the 2004 Mazda Tribute, 2003 Mazda Tribute, and 2002 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
- Using DVOM, measure voltage between generator "B" terminal X-102b (Yellow/White wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair Yellow/White circuit, then retest system. See WIRING DIAGRAMS .
- Disconnect generator 3-pin connector X-102a. See Figure. Measure voltage between generator connector terminal No. 3 (Black/Yellow wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair Black/Yellow wire. See WIRING DIAGRAMS . Retest system for normal operation.
- Turn ignition switch to RUN position, engine off (KOEO). Measure voltage between generator connector terminal No. 1 (Light Green/Red wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair Light Green/Red wire. See WIRING DIAGRAMS . Retest system for normal operation.
- Reconnect generator 3-pin connector X-102a. Start engine. Measure voltage drop between generator connector X-102b and battery positive (+) terminal. If voltage drop is less then .5 volt, replace generator. See GENERATOR under REMOVAL & INSTALLATION. If voltage drop is more than .5 volt, repair high resistance in Yellow/White wire. See WIRING DIAGRAMS . Retest system for normal operation.
