Communication error was the problem, my dad who was helping me do the electrical thought that I said that I had lost all lights exterior and interior minus the head lights no markers brakes, dash lights and with that the original harness that went to the alternator was set aside so when that it was communicated that we should try it with the old harness he said I thought you said that it didnt work I said no it does work at least it did before the old alternator died so we pluged in the original harness and started the splicing there and works great I had problems with some H-4 head lights that I had bought a while but the problem I had with them not being bright and in later thinking I am thinking the original alternator could not keep up with them and may have led to the demise of it. Now it is not a problem at all I would reccommend that if you have not changed to a GM 10si alternator that you do so.
