    Hi Keith,

    Sorry your having all this frustration. I have been there.

    I wouldn't blame the engine. It sounds like the original owner modified the engine and didn't maintain it either. If the original owner changed one thing he may have changed other things and you don't know about. Continental and Lycoming's have their issues too especially when an owner thinks he knows more than the company and modifies it. Modified engines usually have short life spans and problems along the way. If the Rotax is left stock and maintained it will usually out last any air cooled engine on the maint. side. Modified parts don't usually have the thousands of hours test and field time that a stock part has and so you become the test subject for a after market Mfg. because he may only have a few hundred hours or less of time.

    Back to your problem,
    The engine is a little older engine as it has the 4 pin connector. Yes it could be a module, but it could still be a wire. In the Heavy Maint. manual there is a trouble shooting guide that will help you trace the problem back from the pickups. You can download the Heavy Maint. manual right here from this website. You now know which module and wire sets to check since to limited it to just one module. You need to start at the beginning and work forward and you may just find a wire that is chafed, broken or broken inside the plastic plugs. If you need a used module try CPS or Leading Edge and see if they have an older 4 pin used module if it comes to that. It is more rare a module just dies and it is usually a bad wire.

    Mr. Lee,

    Thanks for the quick reply. I really don't blame the engine as I think these engines are definitely the future. This issue happened last night and I checked what I could before it got dark. I am going to try and track down any wires this morning as soon as it warms up a bit....28 degrees here this morning. I do have a maintence manul that I got with the perchase of the plane. I looked through it quite a bit last night.

    I think the piston kit is the only thing the builder of this plane accomplised. He was VERY meticulous and it is nearly a showplane...it is that nice! The second owner bought it.....had a hard landing in a crosswind that bent the landing gear. It scared him and he stuck the plane in the hangar and it was left sitting for the past 11 years collecting dust. I finally bought it after trying make a deal with him for nearly 4 years.

    Took a bit of cleaning and replacing of lines, etc. to bring it back to flying condition.
    I am hoping it is just a broken wire someplace that is EASY to fine. LOL...yeah like that will happen...not my luck. :S

    Thanks again,
    Keith

    PS. I may be in AZ to visit my daughter during Thanksgiving and may come up to Tucson for a visit. She is near Seirra Vista.

    Hi Keith,

    Download the Heavy Maint. manual here on this site. It has some good instructions for that trouble shooting.

    In Nov. your welcome to stop on by. I'll be here.

    Guys Thanks for all the help. I located the problem. Last night I had read that there was a service bulletin about broken wires and had looked last night but it got dark on me before I found anything. Today I dove into it headfirst!!! I did all the diagnosing that I could think of and finally figured out which wire I had an issue with. The red wires that go to the electronic module. It ended up being broken (albeit nearly undetectible) right inside the connector. It looks like it had been crimped on the internal wire but the crimp that is supposed to be done on the wire casing was not done allowing the wire to break. After fixing that one I also found that the other lead was broken where they exited the woven shielding. This was not a complete break but barely held together so it was just a mater of time before it broke the rest of the way.
    Thanks again,
    Keith
