One of my spark plug cables was duct-taped to the cap. Today there was no spark, so I unraveled the duct-tape to reveal a bare wire which was suspended in the cap amongst a lot of grease. Obviously, the kludge had failed and was no longer making contact with the screw in the cap. I know that the cable should end in with a cylindrical port that can accept the screw from the cap. Since this is missing from my cable, can you think of any other workarounds that I could possible adopt to keep this spark plug cable functioning. The only other option, as far as I can tell, would be to replace the ignition coil to get new spark plug wires....but these aren't easy to find. Would it possible to simply solder the bare cable to the screw in the plug cap? Thanks for any suggestions that you might have.
