So, getting back to this, can someone please walk me through doing the Pertronix on an original armored coil? I bought the kit for my cast iron distributor and the diode wire, but IPD's instructions are too vague for a non-electronic guy like me I guess and I don't want to fry the thing... The kit as it comes says that the diode is directional for one thing, but I don't know how to tell the "direction". There are two red 16 ga leads going into the diode bit, one longer than the other. There's a single male spade on the other end of the diode. There are no connectors on either of these red wires. They tell you install the leads as in diagram A on the reverse side of the instructions but there is no diagram A, only instructions for dealing with the tach on an 1800...
The Hall sensor seems straightforward mechanically and has a black and red lead coming off of it. I believe that you connect one lead from the distributor to the male spade of the diode but then I'm not so sure. One of the red diode leads goes to the starter solenoid , the other to a wire that's hot when the ignition is on. Does the "direction" of the diode have anything to do with which of the red leads goes where? And what might be the best spot to grab that hot wire? They give you one of those mid-line clip connectors but I've never been a fan of them; I like terminals that screw down or at least a spade...
Looking for sage advice...again!
