Hi! All  

Sign of times ahead ?  

My brand new 914 will not stop?  (except by fuel switch)  Any ideas ….except external mag kill wires, switches and  shieldings?  

All external wires and switches have been proven OK.  

Arthur from North Wales says someone recently in the USA had a similar problem?  

BTW thanks for trailer responses I believe I’m fixed up from Lincoln.  

Regards

Bob I had a similar problem with my 914 in early days. It boiled down to the

quality of the earthing connections in the mag circuits. Regards, David

Bob,



I would double check the mag switch connections.

When installing a Rotax, I usually check the spark (and absence of) when 

turning the engine over during "oiling up" before first start.

Some info on the mag wire connection here :

All the best with your project,

Best regards,

Bob  

I would check your grounding wires again and again, insure all are connected properly. The engines are all run tested at the factory before delivery so odds are something in your wiring is not correct. Since there are two independent circuits, A fires the top plugs and B fires the bottom plugs both of those would have to be defective from the factory (if your engine continues to run smoothly when your grounded switches are on.) I think you will eventually find it in your wiring.

Hi! David, Gilles, Jerry.

Thanks for your responses.

I now have two new mag kill wires direct from the mag connectors to the

mag groundings (just to prove it isn't my wires or switches) The plugs

still are sparking? An Electrical Contrator also checked it all out and

proved my wires and switches. The dealer is beginning to mutter "damaged

boxes" however I haven't any reason to think I damaged anything?

Don't you just hate when this happens?

 Lastly I would insert an alligator clip (with connecting wire to another

clip) into the grounding Connection right at the module insuring a good

connection with that bullet connector (That is inside that protective

sleeve) then connect the other end to the manifold or other handy metal

engine part. Forget about switches for now. Maybe you've tried this already

but if you do this and get spark, well then I would suspect the wire at the

ignition module, could you have pulled on the connector bullet and pulled it

loose from the wire? Usually when you hear of ignition modules being

defective, it causes the engine not to start or to run rough not your

situation. Good luck.

Jerry

Hi! Jerry

That's how it is now with new wires. BTW They are no longer bullets but

long skinny thin spades. "No Kill" Prevails  .....Me'thinks why the

change ?

I checked with my Rotax guy in Canada and he says to check the installation

manual to insure you have the proper connections. You should have gotten a

bag of parts with the proper pin to connect to your grounding wire and

insert into the top right corner of the 6 pin module plug. That should be

the only "empty" connection left after plugging together. If you don't have

the manual you can down load it at Rotax. Maybe you have done this already.

Good luck again.

Jerry

Bob and all,



My opinion is that the bullet connectors are just good enough for 

automobiles and lawn mowers.

But the latest manuals hardly mention the change. Hence the pictures at 

http://contrails.free.fr/engine_rotax_mag_connect_en.php



One must be careful when crimping the small open barrel terminals, as it 

is easy to crimp on the insulation instead of the copper. Of course you 

may already have checked and re-checked, but did you extract the kill  

terminals from the connector to inspect the crimp and test continuity, 

and make sure they are inserted the correct way round ?

Also inserting a pin direct in the module connector to connect to ground 

may allow to rule out the kill switch, wire and crimp.

Also are the kill wires and module ground terminals connected at the 

same place on the firewall (ground stud, forest of tabs, etc) ?



Best regards,

Hi! Gilles,Jerry,Ron,David,Ivor, Neville etc.

Just a line to confirm that my connection KILL wires were in fact

correct ......wait for it ........ but in the incorrect connector.

Clearly working from PHOTO COPIES DOESN'T SUIT ME ! Oil out of the

exhaust also seems to have cleared.

Gilles ...I trust you won't tell the Jabiru list of my trials and

tribulations !

I'm most obliged to those who made efforts to assist, Ivor with help

over the computer connections for throttle calibration and to Trevor

Pond for the kind help over the loan of his trailer.

The engine is now running AOK it has balanced carbs, FUEL FLOW TESTS are

all  COMPLETED. Hope to get the placarding done, Mod 74 and have the

Flight Test permit available soonest.

Regards to all.

Bob Harrison G-PTAG

Bob,

I promise 

Glad to hear you got things sorted out.

BTW, just before receiving your message I noticed that I was pointing at 

the wrong connector in one of my pictures. I'm changing the picture 

right away.

St Valery (LFOS, between Dieppe and Le Havre) where I am presently 

giving flight lessons until the end of August ? Restaurant on the field
