I can't understand why you disagree about the Chrysler alternators. I did my Electrical engineering tertiary qualifications in the mid seventies. I have worked on GA aircraft ever since. I own four aircraft. How many Chrysler alternators do you think I have seen recently ?
I work on GA in Aussie, and have done so in many other places about the world.
I have to imagine that there is a stash of aircraft so equipped I have yet to stumble upon.
It has been a long time since I last saw the Chrysler alternator, and I think it would have been on a Cherokee Six. They are just not common like the Prestolite is.
I doubt you are talking from experience but possibly from a secondhand account.
The same as the old generators. They would not have been fitted to many aircraft after the 1960's... we, - the guys that work on the machines just do not see many of them.
I have an Electrical category on my LAME licence so I am not just making this stuff up.
While talk of restamping etc may be a good story it is certainly not prevalent.
The aircraft components are not the same as a car.... normally. Yes I have seen MkIII Zephyr parts fitted by some manufacturers, even Girling brake components... I myself have even fitted toilet seat parts, and that was to a military aircraft. (The seat buffer.)
At the end of the day the machine just has to conform.... checked at each annual review in NZ.
Comparing the average GA aircraft electrical system to that of a car is just not quite accurate. I cannot think of a car, or an aircraft that are the same.
Similar yes, but generally quite a bit different.
That would be why you don't see alternator switches in the average car.
