How to bench test alternator

[Perry]

Thanks for the detailed response as always. I tried it without the lamp first. I jumped back/white to the big stud (battery positive) but had no luck. I will try again with the lamp added. The lamp goes on white red and the other side ground, correct? I will let you know what I find out.

I would rather not have to installed the alternator to find out if it works. No where to bring it to get tested on a Sunday. And I don’t think any shops around here have complimentary testing. (No autozone, etc.)
