My alternator went out at 163,000 miles with similar symptoms - the battery light came on but would go out at high RPMs. I was about 100 miles from home and drove back at something like 4,000 RPM to keep it alive. The car started to die literally as I was driving down my block.
Never did any other diagnostics. Just put in a $99 rebuilt unit which has been running perfectly for the last 4+ years and 55,000 miles. |
