Spark Plug Wires
in 912 / 914 Technical Questions
9 years ago
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.
