Alternator Rebuild Kits

unless they fail

Basically I do the tests outlined in the FSMs. Adjusting for the availability of multimeters and other special I don't have.
Of the top of my head I test for:
Shorts to ground in either outout or in the field circuit. For a grounded field alt that can mean removing the ground brush.
Open field circuit (no continuity) or breaks in a winding. Sometimes thats a visual observation.
Field circuit draw test (shown here)
Bad diodes. (on the bench) Sometimes there's a visual clue.
Check for loose studs, bearing issues, etc.

Oh yeah. I got "all that" and if I end up needing something else, I'll get that too. lol

.....and thank you!

Arbor press or a hydraulic.
I don't have a pressure gage so must measure distances and mark.
Real easy to press in too deep.
Also many times a rebuild is missing the grease catcher on the inside. So that lets them press the bearing in deeper than it would with that plastic cup/washer installed. I forget the proper name.
