Anytime you have an alternator tested it is recommended to see what the output voltage and corresponding amperage is.
The "yes it is good" from them is BS.
Check the numbers - output voltage should be between 14.0 and 14.5 volt, failure at any amount above or below those voltages. Testing should be done to load the alternator enough to provide max amperage output. Tolerance is +/- 10% of rated output.
Doctordirt your problem my be a poor connection on the sense wire to the battery or the VR is ready to bite the big one.
I would check the alternator harness, connectors, ground strap and cables from battery to the engine.
