Apologies crude. Root cause is this:

I think you walked the annealing once you said... 'I did notice that wire was abnormally stiff and resisted bending.' That loop vibrated so bad it; for a better explanation, it too annealed the plastic to a clean break. And it had to have snapped right off.

Anneal is that coat hanger going back and forth for some welding rod use. But anneal remains together and no arc. Ah, make sense now. Instant snap when it did. Plastic should have kept it together for arc blackening at the two [jump] points that is broken, but none seen. I would think a milliamp would jump just as a larger volt would leave a trail.

When you said how hard it was to move that one wire, and that's 15 long years of annealing, right? I have to agree that is a clean break do to exactly what you came up with.

Wait a minute.You mean to (not)tell me NO ONE'S seeing that blue wire crease in that blue wire right above it?THAT aint normal.That insulation should be smooth as the rest are.Oh nevermind...if it aint a shadow or grease mark,it looks like it was pinched with a cutting tool....
Kruz..you tellin us everything?

Grn, if you mean the light blue wire, that's the second CAN wire and there is no crease in it, just some grime or smudge marks on there from years of service. I looked the rest of the wires over pretty good while I was in there making the repair.

Hubstinator, the annealing is more of a heat treatment to soften the copper and remove residual stress in the material. I was thinking more of work hardening or strain hardening as a metallurgist would say, from years of vibration. You flex the coat hangar back and forth and the tensile strength goes up with each flex but the ductility goes down until it snaps off. In the abstract, lettuce think of that wire bundle like a heard of sheep, stay in the pack and you'll probably bee OK, safety in numbers and mutual support kind of thing, go it alone though and you get picked off by the big bad wolf pretty quick. I think our broken wire was the lone straggler and yes, it does look like it just broke off clean. I've seen this before when I worked for Continental Aircraft Engines, we had to recall a whole batch of rail pressure control valves for our 2.0 liter diesel engine. The wire harness was failing in about 30 operational hours at the valve connector. We had just changed vendors on those harnesses and there is always a learning curve. In this case they were cutting the harness wires too long and then folding them back on top of themselves. This strain hardened the copper wires and they were failing dam quik under the ever present high vibration levels of a diesel. After that we started sending QC inspectors to the vendor's facility until they could get up to speed.

Work Hardening and Annealing of Copper

Abstract:

This experiment demonstrates the process of work hardening in a copper, that is,
hardening the metal by deformation. If an appropriate furnace is available, it also
demonstrates the softening process of annealing. Copper wire or tubing is quite soft in its
initial state, allowing for a variety of uses where the tubing needs to be bent to a desired
shape. Upon bending, the copper hardens due to work hardening (also called strain
hardening). Enough bending will make it impossible to return it to its original shape.
However, annealing at a high enough temperature causes new, strain-free material to
form and the copper will return to its original soft condition.

I knew what you meant, I just parroted along. Say I watched guys repairing watches. Then it's; you might like this. and I save those for later. They segwayed to watching gold and silver work. Beats me how both ways of heating up the gold and you want to talk about annealing. Hammer it, it hardens an can't move. Heat it up it softens to move again. They can pull it thru a steel stretcher for so many times till you have to soften it up again, because it no longer stretches until you heat it back up to an orange color this side of melting the piece. Very hard knowing that torch can ruin the edge and all that. Looks easy when you do it day in day out. Watching them make a cuban necklace? Lotta work.

So when you said the one lone wire was like a bouncing [hard] spring, right next to the shorter wire, that said to me about working the gold thru the ring holes, stop, heat, work it, stop heat or it cracks off you keep going, right?

If say something laid on it, no filament move in the harmonics. But harmonic it did. Ha! No way to heat the bottom up to anneal it for another 15 years. Too late! There is your hindsight. The lighter to move some molecules back in alignment.

Glad you fixed it Kruz.

Ya Kruzer.Thought it might be a grease mark...

Thanks Grn and Rook, yep, plan to get out on the road with it tomorrow, been crazy windy here the past few days and I haven't ridden anything. @HUbmeister.... yessir, sounds like we are on the same page with the annealing/strain hardening process...

Beautiful morning here in Dallas, finally the hurricane force winds have subsided, going to take the 14 out this morning for a long ride, will let you guys know how it performs.

She ran like a raped ape this morning, everything was working perfectly.

Hi-Tech for the low tech sentence read of the abstract:
The wait here will be right with you ~ How Hub reads the abstract.
Wait here, the waiter will be right with you ~ Everyone else.

Placement Police Look For:
Lettuce Wrap this up ~ Let us wrap this up.
Lettuce open the garage door for Kruz' return ~ Let's open the garage door.

Lettuce the bike cool off ~ Let us the bike cool off?
Let us the bike cool off ~ Does not sound right.
Lets... the bike cool off ~ Ah, that sounds better.

Let- colon placement:
Let's the dog out w/colon ~ Let us the dog out? Lettuce?
Lets the dog out w/o colon ~ is how you read the Hub speak.

And FYI, I heard a miss when you were coming back... Change the plugs.

You crack me up Hub... butt lettuce agree on one thing, I probably do need to change my plugs, still running the original OEM ear rid E uhm plugs butt... my mantra is "if it 'aint broke, don't be a cuck and fix it 'til it is broke!" This philosophy has served me well for many decades. The ZX-14 is still purring like a kitten with a bowl of cream on the originals, so why mess with it? I once heard the statistic that 50% of all aircraft maintenance was caused by prior maintenance, in other words half the mechanics work was fixing what he messed up in the other half.

Scary stats. Got the soapbox up smilie, and the hand pump in the air smilie, about looking at a high performance shop manual saying to change plugs at the 7.5k interval. I waited for the 15k valves. WATT a hell of a difference smilies for everyone. Yeah, who knew?

Because of the center electrodes being flicked off every fire off, eventually the tiny sharp edges are making it harder to jump of a round rather than a sharp edge, I mean, what a jump in performance, or more the driveability of a new set of plugs. Digitally crisp is all I can say.

The sooner the better. Remember the oxy lock on the threads in a damp environment. Lots of smilies to choose from on the road test back.

It might be a good idea to change plugs just so you know they will come out. You leave them in too long, they might rust and then you can't change them.

This black box has me enamored and obsessed. Must be because I'm riding an FI bike. Fucking thing needs a set of plugs for a tuneup. Yeah, I'll go back to carbs.

So I've got a nice argument going with myself really. There is an old switch on a Harley called a VOES. So there are two maps in the black box for a better name for the maps. You WOT the throttle, the vacuum inside the switch more or less pulls to create an OPEN going to the black box. Momentary open at the loop, but electronically.

This is the other curve for heavy load. Other than that, it stays in the other map, rides all day long until that kind of load meets that threshold. Then the other epiphany hits me. It's an Ivan move. Abstract says the load map is used and pretty much says, this map is for safety so when the load comes, the curve will stop it from knocking so we take precautions and use this map for load. Well, that was in the bold black box saying that.

So one, I missed the connection of switching it off and using a blow off screw to set for altitude. Sea level is one, Denver mile is another example. So way back when I had one, took a meter and watched it analog up on the vac pull. Here I'm not thinking about the vac and the blow off.

Here the head is scrambling back and forth, the dot connected to OPEN, only 2 maps, timing retard Tre, backup, sporty ride curve, eliminate the middle curve is the all day runner. Run OPEN, ride the immediate snap to the full curve.

So in degrees, both maps go like this in the numbers curve:
All day runner curve = 10-40-55... analog.
OPEN = 10-55... backup map or default.

All Day Ride map = Smooth linear transition and in analog input.
OPEN = The snap map. Reach this vac load and it pulls up the safer advance curve for heavy load. Then if OPEN, it defaults to, cough, eliminating the retard all day map.

So if the abstract says we save engine from knock, that eliminates the long retard so you stop it from firing way back there lit with a heavy kinetic load? Disaster!

And there you go. I was after moves and not Ivan. So it's cool to see the mother of linear and the mother of code as the first sensor. I had this 101 skeleton I called it, working it in the long so the exercise popped in the head out of nowhere. And this is where this Master Class for me, returned to the V thread and started in with the very first thing to look for and that's input in analog. Got to see it on the one side going in.

The revisit pings me back here and fills another think-out. VOES = TRE... Default map 'eliminates the all day map, aka, the timing retard eliminator. So I had to return to it... if you want to see the primitive side of the eliminator setting a code and seeing either map in their analog or digital settings.

Did that make sense?
