Today, I worked on the Lightspeed ignition wiring. Most of the time was spent actually figuring out which lead went to which coil. This was accomplished by figuring out Top Dead Center on cylinder 1, powering up the LSE box, and turning the engine back and forth with the flywheel. The coil that had a spark jump between the two leads is the one with the 1-2 coil lead hooked up to it. I labeled that lead, and then rotated the crank about 120 degrees in the direction that the prop is supposed to rotate, then found the next coil that was sparking between the leads. That coil is going to be the 3-4 coil. Then 120 more degrees to confirm that the remaining coil sparked when 5-6 was supposed to. Then the whole process was repeated with the other LSE box, and because the sensor is rotated 120 degrees on this box, you have to make sure the crank is really in the correct position.
I did all of this before actually cutting my lead wires to length.
Then it was back under the panel to work on getting the wires to route nicely.
I guess I’m shocked (sorry, pun intended) that you have to manually find out which spark plug wire is which. I must not understand the system at all. Scary to cause a spark like that!
