I'm in the process of removing the engine and found a mass of duct tape around all the engine electrical wires. After cutting away the outer layer of hardened tape I found what's in the photo. More tape! under that was shrink tube over bayonet connectors. Whew! What a job. Also, take a look at the other photo. I haven't looked at the book yet, but I'm assuming either a voltage regulator or something to do with the dual ignition. I'm going to have to label these wires very carefully as some are the same color combo as you can see. Neat huh?
As the Rotax 582 is only a 200+ hour engine, I was thinking of using "hand-shake" connectors with thin clear plastic tubing held in place with small zip ties.
