1997 Isuzu Rodeo 92,000 miles 3.2L V6 Auto.
No output from alternator. Replaced alternator, still no output. In troubleshooting wiring I disconnected the red/white wire at the harness that goes to the generator gain control (in the ECU?). Alternator charges when wire is disconnected, will not charge if wire is connected. No voltage @ this wire KOEO or KOER. Should be 10.5v KOEO and Bat voltage KOER?
Short to ground inside ECU @ generator gain control? Must replace ECU to fix?
