Exactly, and those high amp demands on the alternator kills the diodes, one at a time, over long or short period. Testing for DC voltage with one diode burnt or partially burnt won't show a bad alternator, yet can raise raise the AC ripple to damaging level.
Did not have diode failure in my life, when I had lot of vehicles with high demands.
My bus conversions for example had 500 lb of batteries in it and I had AC run on alternator power with inverter.
The bus was 1972 model, so not that new neither.
