Alternator tear down (1 Viewer)

[Jonathan_Ferguson]

I had been wondering for months why my battery was repeatable going flat. Yesterday I put the Multimeter across the battery and got 12.62V with the engine running and no accessories, and 12.41V with the headlights on. - I used to always get 14.44V

The lack of Voltage must of been a slow and gradual degradation over the past few months, so can I discredit an issue with the Regulator?

Looking in the Gregory's Manual and comparing it to the diagrams on ToyoDIY. [Proxy]
Does Diode Pack equel Rectifier?
Does Suppressor equel Condenser?

What are the chances there's something wrong with any of the Rectifiers, the Stator or the Rotor? - Because I have a feeling it may be cheaper to buy a complete new Alternator from Toyota than the sum of those parts.

I would think brushes.
the others would seem to be working or there would be no difference?

or junk yard alt. then take the time to pull yours apart and see what the brushes look like.
