It turned out that the connector had never been correctly screwed onto the cable. Instead, the cable had simply been pushed into the connector. The problem surfaced after 16 years and 1400+ hours. It may be that all but one of the thousands of engines Rotax has produced, have correctly installed connectors. Nevertheless, if you have one of the Rotax 912 or 914 engines, you may want to check this during the next oil change. For this, the tie wrap of each connector needs to be cut. Then you hold the cable firmly and try to screw on the connector tighter. If the installation was correctly done, you will not be able to twist the connector and feel immediately a hard stop. Then another tie wrap is used to secure the connector. When I did this, on two connectors I could tighten the connector just a bit more. For the rest, the installation was correct. By the way, a cheap source of the NGK connectors, part number VD05FMH, is sparkplugs.com Happy flying, Klaus ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/zenith-list Browse Digests http://www.matronics.com/digest/zenith-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
