What do you mean, alternator fault?
Is the rectifier pumping to much power into the battery & cooking it resulting in the battery failing or has the diode failed?

Not necessary too much power, noisy power, lots and lots of nasty spikes that will play havoc with the numerous ECUs.
An ex-colleague of mine spent thousands replacing the transmission in his Vauxhall Carlton (or was it a Senator?) it kept changing gear randomly, many £thousands later it was returned to him with the same fault. I told him to charge the battery, then unplug the alternator and take it for a drive - problem solved. The transmission's ECU couldn't handle the "dirty" power.

Yep, alternators generate 3 phase AC which is then rectified to DC. Lose one diode in the pack and you get nice spikey DC
