From what I have read; Corona Dope is one of the best products of it’s kind. I would use that but not sure if it is actually necessary in that application.
Yes – I don’t know if that glop of insulating stuff is there to prevent arcing of the 600 or so volts that gets sent to the ignition coils, and/or if it’s there to keep dirt and moisture off the connection. It could be there to keep someone from touching it, but not likely because of its’s location well under the mag-plate where it would be difficult to touch while the motor is running.
Hey – I found I have an unopened bottle of GB Electronics “Liquid Tape” with a brush in the cap. I looked it up and it is rated to insulate at 1400 Volts /mm, and seals out moisture, rated to 200 degrees. That should be plenty for this application – maybe 2 coats. I’m going to try it….mainly because I have it! If it electrically breaks down, I’ll get the Corona Dope.
FYI – I’m putting on a new wire because insulation on the old one is starting to crack (common old Merc problem). I have some stranded, tinned, wire rated for thousands of volts for use in florescent light fixtures. That should seal the voltage!
Thanks again for your replies!
