If it makes no noise at all when you attempt to start it, a neutral safety switch is still in the running. If it clicks or something, I have my doubts about the N.S. switch. The problem in testing for this is that it must be having one of it's little fits while you are testing. Otherwise things will test normal. Just remember, as Amervo brought up, all things electrical begin at the battery, so be sure to validate the battery's integrity as well as the power and ground connections. Hot spots, just as Bjorn pointed out are true indications. BTW, I run a 428 in mine too. Ton o' Fun wouldn't you say?
