Good morning all,



I have new plug caps and the boots for my 447 Rotax.  I gently pulled on 

the cable to remove it from the SCDI component but it didn't easily 

unplug, so rather than damage a $500 item I'm throwing the question out 

to those who have performed this procedure.  Would someone who knows 

please  instruction me on how to both remove the caps from the cables 

and the cables from the SCDI?  I'd appreciate it very much.



Thanks in advance,

Dave K/Kolbers:



If I remember correctly, the caps and modules are equipped

with a threaded stud.  Wire must be unscrewed.  Right hand

threads.

Look inside the cable end of the new cap....you will notice that they 

unscrew...Should be the same for the Ignition module end...Herb

Thanks, George, John and Herb,

Done!  When I read the caution about removing the cable from the CDI, I 

decided to undo the "package" of cables, etc. that Don made, which I 

wouldn't have had to do if I removed the cables from the CDI,  remove 

the cap and replace the boot on the CDI, which rotted away, put on a new 

cap and re-do the cables, etc.  I now have a spare boot and cap in case 

the other boot rots.  The whole re-installation of the 447 turned out 

very nice.  Hope it does as well in the air as it looks good on the ground!

BTW, when I was online getting the torque values for the IVO, I came 

across the story of Ivo and his escape from behind the Iron Curtain.  

Very interesting!  If you never read it Google it, it's a good read.

Dave, One last thing about the threaded fittings on coils and caps. Don't just unscrew the old cap and screw on the new one. You need to cut off the old threaded section of the cable first, then screw on the new cap. Same with the end that screws into the coil. Doing this creates a firm connection and prevent internal arcing that degrade ignition energy and performance. At least that's the line in Rotax classes.

I should have added that you only need to cut off about 1/4" (~6mm). Just enough so that the screw fitting is going into new wire.

Rick,

  

 Glad that you added that bit of info.  I thought maybe cutting off the  ignition wire might make it too short.  If you're replacing the spark plug  caps, I guess it might be a good time to replace the wires with new ones  anyway.

Bill V/Kolbers:

 

Copper core wire should last a very long time.  Can check with an OHM Meter to see if you are getting resistance in the wire.  Disconnect from the cap and coil before checking.
