Always with the confusion. The 73 F100 351C 4v quit charging. Replaced the alternator. Drove 70 miles with about 10 stops and restarts, battery discharged. Zero. Zip. New battery. Made the same trip, battery half discharged. Swapped old battery back in just for curiosity's sake. Same trip. Battery about a quarter discharged. Now she seems to be running fine, except the battery never gets charged over about 75%.
Plan on completely rewiring this spring. Do the electronic VRs work very well? Is it necessary to use a field relay like the later model truck? How does one mount a heavy duty fuse to replace the fusible link? What should such a unit be rated?
