Subject: | Spark Plug Wires |
I was putting the plug wire back on one of the lower spark plugs and the wire just
crumbled in my hand. It appears all the bottom plug wires are brittle and
need replaced. Do I need to replace the upper ones too? All the wires are original,
650 hours on them.
I have gotten the old spark plug cap off and it appears reusable. The wire appears
to be normal wire core spark plug wire that I can get at an auto parts house.
My question is how to get the old wire out of the ignition coil. I understand
the wire twists into the coil like it does the spark plug cap, but there is tubing
similar to heat shrink on the wire and over the end of the coil. The tubing
seems to prevent "just untwisting" the wire from the coil. Do I cut the wire
near the coil and slit the tubing to get it off? Can I reuse the tubing?
If not, is it just heat shrink and what size? Do I need to purchase it from
Rotax?
Can the wires be removed from the coils without taking the modules and coils off
the engine?
The spark plug cap measures the proper resistance, so can it be reused? How do
you measure the pull off force required? Is there a source for the caps that
is less expensive than Rotax?
Thanks for your help.

I would replace all upper and lower without question. All caps also. This ho you
