I just go my 2000 Ranger Trailhead back together from clutch/tranny/engine maintance. The truck started right up but I'm not getting power from the alternator. I pulled the alternator and bench tested it, and it tests fine. I have continuity in the blk/org primary wire up to its ring terminal @ the power distribution box but not past it. I have a feeling the problem might be the 125 amp mega fuse But am not sure how to test it. Should I be getting resistance between the 2 flats of the fuse? What else might I want to check?
