Bad Alternator?

I've been thinking of a H6 for a long time.

Batery/altertnator outputs easy to test.  I'm thinking maybe the problem is the alternator is not being spun fast enough.

or maybe a bad  replacement alternator.

 

Too bad they didn't give one extra detail, "charging problem" is ambiguous.

Normal wiring issue (connection, wiring, cleaning) or bad aftermarket alternator are most likely without knowing anything.  If a competent shop didn't do the work there's no telling if it's just something they're doing or missing. 

In the past there were numerous complaints of aftermarket H6 alternators not working properly.  But identical symptoms two alternators in a row? Seems unlikely.  unless during the first repair attempt they replaced the battery and alternator at the same time so to speak and they fixed the original charging problem but introduced another one - which the newest alternator mimmicks, because it's no good or not H6 compatible. 

The H6 alternators have a reference signal from the ECU.

they are a nice car - the other half has an 06 LL Bean.

quite possible incorrect alternators from parts store.

Could be a bad ground somewhere.

Thanks for the feedback.
