I have a prestolite distributor with a pertronix conversion, no computer module. I recently replaced the alternator with what I believe to be the wrong type. The last one I had had a big square box on the back, the new doesn't have that, it has a field wire connection which tells me that it has no built in voltage regulator. The old one had two wires running to it; a battery terminal, and not sure what the other wire is.
