Ken,
I took the readings per your instructions. At step 1 the alt was putting out over 16 volts.
I removed the alt took it to Auto Zone it failed the test on their machine. They replaced the alternator under the warranty.
New alternator also puts out 16 volts. The GOOD bulb in the alternator indicator does not light when key is turned on before starting.
Voltage at the alt wire connecting to the gauge cluster in the dash is 0 with key off 12+ with key on 14+ with engine running. So I assume the bulb not lighting is a problem with gauge cluster circuit board or contact points on light slot on the board.
Isolator readings are as anticipated from your flow chart except that the alt wire when disconnected from isolator with engine not running still reads 12+ volts.
Isolator is new- alternator is rebuilt-
How does one verify that the sense wire is functioning? How does the light failure affect the sense wire system?
