I recently ordered a set of replacement spark plugs cables from CA-Cycleworks. When I fit the cable into the OEM coil on my 1993 Ducati 900 Superlight, I noticed that there is no threaded post in the coil to twist the cable onto. Instead, there appears to be a small metal contact inside of the coil. Since the new cable does not fit snugly in the coil, I am curious how I can assure that there will be a snug connection. Leaving a couple of millimeters of exposed wire & then using some silicone adhesive to bond the outside of the cable to the body of the coil seemed like a possibility. But there might be a better way. I would appreciate your thoughts. Thank you so much.
I think you might need something like these https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/232610192709
Thanks, Derek. I am not sure that these inserts will fit into the coils. Since the OEM coils do not have these inserts, there must be an alternative way to make a solid, vibration-proof connection.
I don't know if you are talking about the early, grey, dumpy looking coils but unless they are a variation of the type that are usually fitted, then you cannot remove the wires from the coil without wrecking them - you will probably guess how I know this. It's true that it will still work after a fashion by inserting a wire with a clasp due to it's close proximity with the broken off wire, but it's not ideal and not a path I will be following. The later black, longer bodied units are interchangeable with these and they do have removable wires. Alternatively, you could uprate/replace your coils at the same time with the units from Chris Kelly at C.A.C.
Thanks, Chris. Yes, the bike does have grey OEM coils. The thought that the cables were permanently attached to the coils did occur to me after I removed them. However, the ends of the removed gave no hint that the cables broke while trying to disconnect them. Nevertheless, I suspect that you are entirely correct. Well, I planned to replace the coils anyway, right? I guess it's time to call Chris at C.A. C.
I'm sure we could carefully gouge around in the plastic surrounding the broken wire to expose enough to solder to, but it would be pretty messy and an absolute last resort/last coil left on the planet course of action.
I agree. I plan to call CA-Cycleworks tomorrow. I can't say that I am too distraught since the bike I having an ignition issue & the coils could be suspect.
