Probably got myself in over my head, but I had dual lightspeeds installed on my IO540 from Performance Engines.... has anyone else gone through the process of hooking up the coils and tach's? I've got an AF3500 with a backup std Van's tach.
The leads coming from the black boxes are labeled A, B and C, one box on each side.... is there an easy way of figuring which wires go to which coils?

I've got dual LSEs on my engine also. There is a procedure in the install manual for connecting the coils and figuring out what gets hooked to what. http://www.lightspeedengineering.com/Manuals/Ignition.htm

As you noted, the controller box has outputs labeled "A", "B" and "C". As I recall, the procedure is to connect the coils to the boxes with the plug wires disconnected and then rotate the prop (or a magnet) to make sure the coils fire at the appropriate time. It fires opposing cylinders at the same time and you'll get a spark at 0, 120 and 240 degrees of rotation. Make sure when you rotate the prop (or run the magnet past the sensors) that you're going in the correct direction.

I THINK that the correct hookup for my Plasma IIIs was "A" firing the coil for cylinders 1/2, "C" firing the coil for cylinders 3/4 and "B" firing the coil for cylinders 5/6.

Don,

There should have been a manual included with your LightSpeed ignition. The same manual is on their web site:

http://www.lightspeedengineering.com/Manuals/Ignition.htm

It's pretty well written and explains all the installation and testing process.
