Pick up coil issue?

[DEEBS11]

These areas are very suspect. When the rubber outer cover of the wire is cold they can give a false continuity check because the material is condensed and holding the broken pieces together. When the rubber is warm from a hot engine, the now softer material can stretch slightly and separate the inner wire core especially with a vibrating motor and the twist of the advance unit.

Hi shopteach, It is a good preventative measure to isolate the neutral safety switch wire into its own loom. Also remove it from the Molex connector above. This mod helps when riding in wet weather or after washing misfires. Since you have the hard part done makes it an easy job.

I've had two cylinders become mostly dead after washing. I believe this was was the cause. Cleared up after a few days.

I think what is happening with the dropping of 2 cylinders in wet conditions is water gets splashed/directed in the area of the loom connector behind the fuse panel. A solution for this is to wrap the connector with electrical tape in such a way, so no water can enter there.

Makes sense, since the wires are insulated in the other locations.

You can also put a LITTLE bit of dielectric grease inside the connector to keep the water out. I know some on this site do not like it, but Honda, Toyota, and older GM's all used it. The change is the "new" weatherproof connectors now being used by almost all the manufacturers.

I had to replace my crankshaft seal. My “bigger the blob the better the job” repair was temporary and probably made on the side of the road. Certainly not in my own garage. It has been so long I don’t remember doing it, only that I needed to do it over before it failed.
It may be after the holidays before I get after it.

The wire used was meter leads. That’s best use of a cheap Harbor Freight meter.

I use this stuff.

Yes, I have some of that silicone wire on hand. That’s what I’ll be using. That, and some half length butt splices (uninsulated) if they’re small enough to grip the wire.

I was anal about matching the colors.

I used solder/heatshrink, which I know solder is not the first choice of JetmechMarty, but I was happy with the results.

And I see you did NOT pinch the wires tightly with the clamps! THAT is why they break in the first place. When I took delivery of my first XS1100 in September of 1977 the dealer didn't have a mechanic. I assembled the bike from the crate and rode it out of the shop. I had a miss about six months after owning it and traced it to a broken pickup coil wire. I had the shop owner send Yamaha a note that they pinched the wires too tightly, and it caused them to break. Never heard anything back from them. I loosened the clamp so the wires could slide as everything moved and never had a problem with the pickup coils. I did sell that bike after about 4 years and 35K miles.
