Electrical problem
2000 Ford Taurus 6 cyl Two Wheel Drive Automatic 172000 miles

I have recently been having an issue with my beloved Taurus. The battery light intermittently will turn on, and only goes off when I put some really high RPM's on it.

I've replaced the battery at the suggestion of a local mechanic, but that didn't do anything. They said my alternator was fine.

It has failed to start twice now, each time making a high-pitched whine. The whine is constant, not ticking.

GENERATOR LOAD TEST
Ensure drive belt is in good condition. Replace belt as necessary. If belt is okay, connect charging system load tester in accordance with manufacturer's instructions. Start and run engine at 2000 RPM and apply load until generator output levels off. Generator output should be at least 58 amps at 2000 RPM.

GENERATOR NO-LOAD TEST

Connect voltmeter positive lead to B+ terminal on generator and negative lead to ground. Start and run engine at 2000 RPM with no electrical load (all accessories off). Read voltmeter when voltage stabilizes. Voltage should be 13-15 volts.
