SC Spliced Coil Wire?

[ArchHibb]

Replaced the distributor cap and rotor on the SC tonight. Had to dismount the coil to get the cap off and noticed electrical tape around the wires leading into the coil. Unwound the tape and discovered the brown wire is two pieces just twisted together!






I know the coil delivers a pretty big jolt to the distributor. I could solder the wire to ensure it won't separate, but will this interfere with current delivery?


Also, (while I've got your attention...) I noticed one plug wire connection to the distributor cap has corrosion on it. I live next to the ocean, so exposed copper corrodes quickly, but obviously this one is not like the others. What's the general consensus - a loose plug wire?

new cap and fix that coil wire is in order, MANY high voltage goes through them wires, be carful. I would use a 3M scotchbrite pad to clean the wire and treat with a little electrical cleaner.

Bump for further opinions if it is okay to solder the coil wire.

Upon further consideration, am I correct that the 2 wires leading INTO the coil are 12v and it's only the single fat wire coming out (going to the distributor) that carries the big charge?

That wire can certainly be soldered, my preferred fix would be to simply replace the end of that cable where the connection/splice is currently, if you can find enough slack to reach the connection point on the coil.

You should solder it!!! That is if it can't be made to fit with just a new connector. I assume not. Use some heat shrink tube on it to insulate and protect it. Yes, they are low voltage wires that go to the posts. The BIG wire is the high voltage sparky one that will cross your eyes if you hold onto it :-)

Corrosion like that is bad. I would change the car and rotor and clean/inspect the lead ends carefully. That is usually caused by water getting into the car thru the boot. Maybe rain, maybe someone washed the engine once upon a time. Clean it up and push the boots down tight. With electrickery, cleanliness is your BEST friend!!

You should be able to strip back a little of the outer plastic casing on the 2 wires to the coil and have enough slack to reach. Crimp new connectors on them and reattach. The white wire is positive. The brown is negative.
