I come back to this alternator.
Is it normal that the starting torque is so huge (see the data on the post replacement of the pale hub with larger ones)?
You really have to force it to spin it.
Before checking the poles and coils and do it for nothing. Do you think this is normal?
The curves on the oscilloscope seem correct when entering the rectifier bridge.

I never put my nose in an alternator.
But can you easily take out the coils (stator) from the carcass to leave only the rotor?
In place on its bearings.
I know that a vacuum induced rotor has no resistance to turn.
As soon as the bottom bearing is set askew.
The magnet rotor axis is probably not the same diameter as the original delco induced rotor axis, so the bearings would be changed to fit the new axis.
And put your finger in the bearing to see if it is perfectly free.
And if the N45 magnets want to kiss the iron carcass of the coils. Hard to separate these lovers The force of attraction is immense.

It's funny because I had the same ideas as you.
Between choosing the ista or the Missouri. Doubting customs for Missouri and none for the ista. Turkey = Germany = EEC.
Missouri is a class above at all levels. Vibration, weight, Ampere, Voltage. But like any good beginner I made it easy.
The proof: I haven't taken a shot yet ...
And I did not stick to the wires in operation

Hard hard
You have noticed that the rotor is spring loaded, you can push it in. He then takes his place.
It must move the magnets in front of the coils if too windy. To limit production. And to burn everything behind by storm for example.

You have a spring in your machine because I have nothing. The stator, the rotor of the washers everywhere and that's it

Yes, I noticed it by putting the axis to fix the drill.
A good blow of the hammer and I see the axis which returns of 1 cm "Ho SHIT ..."
It comes out all alone "OUF"
It must be security in high winds.
Or if it falls off the mast it hurts less on the nose
I look closer, it slides in the bearing.
On the drill bench (500w to check) fully injected on GTI around 170W, I sink: it drops immediately to 140w I release: it goes back up.
I will have to open it, the joint between the black collar and the white frame is cracked, to put a silicone.
