Replace coils?

[ridesolo]

I'm in the process of cleaning up the bits n pieces on the CL378 for reassembly and discovered that one of the spark plug boots has broken off the cable from the coil. It looks like this was originally manufactured w/ some kind of resin (or something) holding the cable in the housing and it looks like something I'm not going to be able to easily repair. New coils weren't in the plan or budget, but is that my only alternative?

I think I've seen people repair them before, but in similar situations I usually replace them.

Not sure if I'm understanding correctly. But if you're talking about the boot itself, NGK makes replacement boots for every application. No need to replace the coils. Just cut off 3/8" of the end of the lead coming from the coil so you get a fresh grab, and screw in the new boot. All it is a "screw" type threaded piece inside the boot that bites into the wire and holds it in place.

If you're saying the actual wire has come out of the body of the coil, you can dig out the old wire and all the resin and epoxy it back into place.

I have a pic of me fixing the stock coils, but I can't seem to locate it. They're actually pretty easy to fix. If you pull the wire out of the hole, there is a small screw set into the coil body that looks like a sheetmetal screw. Sometimes, instead of a screw they have a brass pin. In either case, the wire is pushed or screwed into the hole and the epoxy is there just to keep it from being pulled out. I have replaced the stock wires with 8mm Accel or similar auto spark plug wires and brand new NGK caps. As long as the coils check out with a meter, definitely just replace the wires and roll.

Found them:

Here is where I put some epoxy over my replacement wires before putting them in the holes...

This last pic shows the completed coils with new points and power leads soldered on.

Thanx all. It looked like the plug wire had broken off at the boot. After reading comments from y'all I discovered that what looked like hard epoxy or some kind of resin in the plug boot was more like soft tar. I was able to dig that out then cut about a 1/16" off the end of the wire and screwed the boot back on. All seems secure now so I guess I'll find out if it's good when the day comes that I start kicking away w/ fingers crossed.
