I found the latest YouTube video from the Car Care Nut (link below) on alternators very interesting, especially the bit about when a Diode in the alternator fails and can cause havoc with a cars electronics and modules.
Makes perfect sense to me how it can cause electrical/electronic issues and something I have never thought about.
I knew the general theory of how the alternator works from my electronics days, generating AC - rectifying to DC and smoothing etc, but the 'way' it does it with 3 phases and how the voltage output is controlled was interesting.
Maybe some of the strange electrical/electronic issues owners have is down to a faulty alternator in some way.
