9912ULS Ignition Module Issue, maybe

I think that Ignitech have been in the business of designing and building motorcycle ignitions for many years and now knows how to make them reliable. It is unfortunate that the Ducati ones give grief. They only needed to make a few improvements to the design and it would have been bomb-proof. Mark Kyle in Australia did some excellent work to improve their reliability.

Old Ducati modules don't have much value, particularly now you can buy alternatives for such a low price. In the UK I would look on www.afors.com or you could just search for sold listings on ebay.

The myth that the modules are Ducati needs to go away.

RW qoute;,

All...seems a lot of people don't understand the ignition system. First, it is not made by Ducati. That old idea comes from the fact that Rotax purchased the plastic box from them and left the Ducati name on it. The circuit board is made in Austria and the design is a Rotax one. Over the years many changes have been made on the circuit board and some 12 years ago they got Ducati to delete the name on the box....done. The stator has been made by Ducati but the electrical circuit in the 9 seres never has been.  

Regarding the injected engines with a computer and fuse box. There are no SMD modules in that system. The firing is controlled by the computer and is not the same at all. Glenn is correct on that. 

Lastly if your engine is at the point where the modules are giving up, normally that is about 10 years from what I see, sure look at aftermarket. it is extremely rare to find new parts fail within warranty and even then I know of goodwill warranty given to engines with low hours and well out of warranty. The worst years were about 2006 when they had a huge ramp-up of production for the LSA aircraft that were flooding the market at that time. The root cause was the circuit boards were not always placed in correctly and would not cool correctly as the small bits got bent on insertion to the box. (my view) Sometimes these would then have a bump form on the box (the term pregnant was used to describe the condition). Sometimes people would continue to fly hundreds of hours by putting a bag of ice on the box to start the engine. It is fair to say people just refused to give up on a failed box until they could not start the engine. 

I am unaware of any major issues since the big changes in 2010 with the change over to the "soft start" modules. The internal parts were improved and the circuit board seems more robust. "
