ok I give up on toyota alternator parts, I am installing a gm 1 wire tomorrow. made it through my wheeling trip and back down the hill, and I think half way back from fordyce, or closer to home I started loosing charge. I got back with 10.6 volts. I checked my charge lamo relay, 2 prongs were broke loose inside, soldered them and no better. the 84 copmressoer bracket, some 1/2 tube and a 6 1/2 long 3/8 bolt will start my conversion. then a complete toyota charging system bypass, and a aftermarket voltage gauge install.
