2006 V6 vibrates when alternator takes electrical load
Hello all,
I'm new to forum but an old mechanic at heart. My 2006 V6 runs great, but while idling, if I turn lights on or blower increase, or windows up or down, I can really feel the alternator taking the load. It vibrates the whole car for a few seconds while it works hard. Is this normal for this year Mustang? Any past issues with alternators?
Thanks all!

True, engaging the AC compressor puts a lot of drag on the engine. Just putting windows up/down shouldn't cause the alternator to act that way though.

I'm going to check voltage on battery while engine is on....I was told that voltage should be no less that 13.4 V. Then I think I will remove belt and spin alternator to be sure bearings are good. Then take it to auto parts store and have them test alternator. Sure seems like excessive drag on engine when load is put on it. Yes, I can feel A/C compressor come on and that's understandable to feel that load.

Check the belt tensioner.
The high speed radiator lugs my engine but it does not 'shake'.
It seems that your 'bucket' or battery is shot and the alternator
is having to produce all the amps for the accessory loads.
