I would not hesitated to get another one if needed. I also moved my modules to the firewall side of the motor mount to avoid broken wires in the future. If I was you, I would maybe fix both modules you have, install one of the aftermarket ones, and have a spare Rotax one if you ever need it. JImChuk

    As Jim mention, probably a good idea to have a spare. I had a persistent issue with my modules several years ago. Substandard wire in them (in my opinion). Several areas of the wires broken inside of the insulation. I had to cut/spice/repair several sections of my modules and wires from the stator.

    Granted I come from experience in building military grade electronical test equipment for fighter aircraft, so was used to using very high quality wires. The wire that Rotax (ducati) uses is pure junk!

    Thanks everyone, appreciate the input! I ended up buying two new modules from Allistair. I will also redo the wiring on my old Ducati modules to keep as a backup set. I'm lucky enough to live down the road from Rotech, so I went and talked to them about repairing the modules. Once I get it all complete, which will likely take a while, I'll try and post a couple pics in the event it can help someone else out. Thanks!

    Yes, crappy wire! I had to buy a replacement module for my 912ul and the cost was eye watering. I could buy a new magneto for that price! You would expect better quality for the money.

    Who is this Alistar that you're all talking about and how do I get a hold of him for a price on modules with the "soft start" feature built in?

    What is the concept of "Soft Start"? I've seen it referenced but, I don't really know what it is. Would someone care to edify me?

    The soft start, at least on these aftermarket modules uses 12 volt power from the wire going to the starter solenoid switch for low rpm spark. When the key it turned to start position, starter engages, and ignition module is energized. Otherwise the modules don't generate spark until about 300 rpm. When key it turned off start position, solenoid and module don't receive 12 volt power. JImChuk

    AND it is "soft start" because it retards the spark timing (hopefully to just after top dead center) for a couple of seconds to help prevent kickback. That's a problem on 912uls and will damage the starting clutch.

    Yes, what the two previous guys stated. It basically retards the timing on ONE module (you're suppose to start on one module and then turn on the other module. I have mine wired to two toggle switches. One for each module. Bullyhawk was the seller I got mine from, but not sure if they are still available.

    I have never heard this before. I always start mine with both ignitions turned on. Why would you only start with one ignition?
