Okay, so I have read through the various posts of converting the points ignition to electronic ignition. I got the Ignitor II module and the matching Flamethrower II coil. I have installed the ignition module, but I am stuck on the coil and what to disconnect off the old coil and connect to the new. This is for a 1988 Mercruiser 3.0 l engine.
Here is a picture of the coil that is in there right now. It has a purple/yellow wire and a purple wire which are joined together into one connector and hooked up to the + side of the existing coil, then a grey wire (assume that is the tach signal) and the black wire from the points/condenser on the - side.
So, my confusion is which wire do I need to remove from the coil, and which do I leave? The wiring diagram I have in the service manual (#10) says the purple/yellow wire is the "Ballast bypass", and it runs from the coil + to the starter? here is a picture of where the purple/yellow wire goes into the starter.
The purple wire shown in the wiring diagram going from the coil + is labeled "purple resistance wire" and shows running from the coil to where it splices into the purple choke wire (too many friggin purple wires here). One problem I have is that I can't find where that splice is. Now, everything I have read on other threads dealing with ignition conversion says to splice in a wire from the purple choke wire BEFORE it joins the resistor wire. Would this be the wire I need to splice from then run to the coil +, and would it be okay to do it right here where it runs from the wire bundle to the choke?
Here's another question; can I simply separate the purple-purple/yellow wire that is connected to the coil +, tape back the purple (which I assume is the resistor wire), and leave the purple/yellow wire for my 12V? That purple/yellow wire runs to the starter, and connects up to a small post right next to the big honkin red wire from the battery. Not sure if that provides 12V when the engine is running, though.
Anyway, I am looking for any instructions as to how to proceed, which wire to tap into, and where. Other than the coil, this whole conversion thing was pretty easy. Thanks in advance for any help you all can provide.
