Ok folks, tell me your ideas about why I have no juice to the starter. I've got my 72 with 350/TH-400 all back together after an engine and tranny rebuild. While the power train was out I went ahead and put a new engine harness in. Now, all bolted and wired up, I've got zero juice to the starter. I turn the key to on, everything is ready to go. I turn the key to start and it does nothing. I mean nothing. What's really puzzling me is the attempt to start it kills all circuits. The display on the radio goes out and when I release the key from the start position, the radio memory is wiped out just as if I had disconnected the battery. I'm looking for suggestions about where to start my search for the source of the problem.
