I opted to install the new plug wire similar to the original setup,
with a few changes.
I never found the old contact spring, but assume there was one there.
I dug through my stash of springs and altered a compression spring to fit.
I later trimmed the outboard end of the spring shorter than the photo,
as I was afraid it could arc on the mag plate.
I soldered the end of the plug wire to the spring.
The old rubber bushing under the knurled nut was shot, so I made one
that seem to work good, out of an old style, hard rubber faucet washer,
that already had the correct taper to fit in the knurled nut correctly.
I had to drill the hole in the rubber washer out bigger, to 9/32″, so the
plug wire was a snug fit inside of the washer. When the knurled nut is
tightened down, it seem to hold the wire fixed tightly in position.
I wrapped electrical tape around the spring (inside of the original glass
insulating tube), leaving the end of the spring bare, as to contact the
secondary button on the coil. Before installing it, I put a generous amount
of silicone grease on the secondary button and inside of the spring,
to prevent corrosion. For extra luck, I used some liquid tape around each
end of the glass tube to help keep moister out, and put some around the
plug wire inside of the knurled nut.
After all said and done, I rechecked the ohms, and got the same reading as
in the one photo.
Time will tell if it’s successful…… but then again, I’m not even sure it’s going to have
enough compression to be a runner.
Prepare to be boarded!
