A few months back I replaced the generator on my 62 impala with a three wire alternator. Since I've made this change, my dummy light hasn't come on when I first turned the key. I figured the bulb was out and because the alternator was new, I didn't bother looking at it until this morning. What would be causing lack of the light?
I've read a bunch of treads on this forum and come to the conclusion that I have it wired correctly and the Wheatstone bridge should be detecting the current even though its not factory.
