2.3CL & 3.0CL
- Disconnect generator (alternator) 4-pin connector. Start engine. Turn on headlights (high beam). Using DVOM, measure voltage between generator 4-pin connector terminal No. 1 (White/Green wire) and battery positive terminal. See Figure. If one volt or less exists, go to step 3. If greater than one volt exists, go to next step.
- Turn headlight and ignition switch to OFF positions. Disconnect 31-pin connector "C" from Electronic Control Module/Powertrain Control Module (ECM/PCM), located behind right kick panel. Using DVOM, measure continuity of White/Green wire between ground and ECM/PCM connector terminal No. 2. See Fig 1. If continuity exists, repair short to ground in White/Green wire. If continuity does not exist, install a known-good ECM/PCM and recheck system. Replace ECM/PCM if necessary.
- Turn headlight and ignition switch to OFF position. Disconnect 31-pin connector from ECM/PCM, located behind right kick panel. Check continuity of White/Green wire between ECM/PCM connector terminal No. 2 and 4-pin generator connector terminal No. 1. See Figure and Fig 1
. If continuity does not exist, repair open in White/Green wire. If continuity exists, test generator and regulator. See GENERATOR/REGULATOR OUTPUT TEST .
