I'd guess that Himalayan mystics, if they've committed hard enough and long enough to the cause, can maybe obtain something close to the state of complete mental relaxation and well-being, that comes from being all alone in the workshop wiring a bike, with plenty of time and all the right kit, and a good audio accompaniment.  Bike to good home - Page 5 112350

Geez guys - have we all been on the whiskey tonight??? Very Happy Very Happy Very Happy

New FICU loom is on the bike and all connectors that I want to replace have been replaced. Guess what arrived today?

http://www.simpilot.net/~sc/brick3/89b.png

Now try it, ya bastid!

Still got to make a new throttle cable - the remains of the old one is visible on the bench.

Another option is to try to avoid a fire with a circuit breaker, where the circuit trips almost instantly, in case of a short circuit. It's a quick and simple modification.

Back in the days, people sometimes pampered their pet projects with add ons like a Frantz filter or a circuit breaker, you don't seem to see these things anymore.

There's a thread about it in the "How To" section.

Power source was no.1 fuse... which didn't go phut, indicating that the current draw was under the fuse's surge limit and yes, the fuse is the correct amperage Very Happy . A circuit breaker might possibly have stopped it, I agree.

I made the new throttle cable yesterday but forgot to take any pics. Basically, up where the square bit is that links into the chain pull, I soldered on a 4mm length of 3mm OD / 1.5mm ID brass tube. After the end of the inner wire had been smacked with a birdcage (https://www.venhill.co.uk/tools/all-tools/cable-inner-wire-bird-caging-tool-vt13.html) and the two parts soldered together, it fitted into the slot very nicely, thank you very much.

I make enough control cables to justify the cost of the birdcaging tool but I didn't pay that much for it! When I bought one it was £92 including tax and shipping. And much as I would love a solder bath, I make do with an 80watt soldering iron. The trick is to apply heat to the brass nipple but to apply the solder to the birdcage. Once the solder starts melting on the wire you know the whole assembly is hot enough.

Yep I'm thinking green/yellow goes into fuse 1, rather than out, so the short might bypass the fuse.

Okay.... I can't begin to say how fckn pissed off I am. Just went to clean the underside of the fuel tank, so I laid it very carefully on a soft towel. When I turned it back again, fuel had leaked out (as expected) and stripped the clearcoat. Has to be my fault; one or more layers were just too heavy and didn't go fully hard.

I just cannot find the enthusiasm or heart to start again, so I'm on the lookout for an '86 onwards Bermuda Bronze tank. Even buying from Motorworks or James Sherlock isn't going to be much more than the cost of another load of paint, but if anyone has one?

lol! Funnily enough, I intend to reassemble it this afternoon, make sure everything's okay and to hell with it until I can locate a new tank. It doesn't stop me riding it; it's just as ugly as hell. Just to reiterate: absolutely and completely my own fault. I don't blame my tools unless the buggers break (which has happened mid-use, but in that case Teng replaced the offending item within three days).

Replacement tank arrived yesterday from Motorworks. Most of what look like scratches in the pic are actually dirt.

http://www.simpilot.net/~sc/brick3/91b.png

When trying to start it last weekend, nothing. Not even a click of the load shed relay. Mmmm... right. Grab a handful of wiring loom and give it a tug. Cough, grumble. Big sigh. Looks like I haven't found the intermittant wiring fault after all, so we're back to this:

http://www.simpilot.net/~sc/brick3/90b.png

It's getting a spanky new loom. I spent way too long this morning trying to identify the pins that fit in the two-way AMP connectors for the clutch and brake switches etc.. Don't bother. I did eventually find them on the TE Connectivity website but they are £3.29p per terminal - that 's each - you didn't misread it. So that's £39.48 + VAT = £47.37p plus P&P for the twelve terminals required on a wiring loom. Fifty quid for twelve tiny tubes of zinc-plated brass. Back to the miser's trick of cleaning them up, opening up the end pair of crimp ears (the insulation grips) with a pair of wire cutters, soldering on a new wire and then re-crimping the insulation grips.

Alternatively, buy Molex 0.062"-series terminals and housings and hope the AMP connectors live happlily ever after in the bin  Twisted Evil

I appreciate originality as much as the next person, but I have no problem with junking thirty-year old connectors and replacing with something spangly and reliable - it is the wiring after all, and it needs to be reliable. You wouldn't persist with thirty-year old spark plugs would you?

And completely (or mostly) off topic (what moi!) the wife has decided that I must spend a slice of my later years towing a caravan on the nation's highways. So, instead of flamboyantly slashing through the traffic jams on a two-wheeled sabre, I now am the traffic jam, oh well. Anyway, this meant that yesterday I spent much more time than I wanted to, figuring out how to disable the rear parking sensors on the CR-V as I fitted the new-fangled 13-pin electric hook up. Boy was that complicated, I was hoping that the hundred and seventy quid that I'd shelled out on a 'plug and play' (har bleeding har) wiring kit would address this issue. Instead, the kit and the instructions gave me three wires from a module (COM, NO & NC - some 'module' huh?) and told me to go and refer to the 'Owner's manual' to figure out where I'd need to connect them, thanks, I'm so grateful for that. After half a day of toil, I sat down and reflected on the day's troubles. Reflection is good, because it was at that point that I realised that the CR-V comes with a very useful switch on the dashboard - that disables the rear parking sensors. 

So, The Kurse persists......

If you was just wonderin if this wuz done - NO IT AIN'T!!!! Evil or Very Mad 

It got a spanky new built from scratch wiring loom which worked first time. Almost. I reversed the starter motor/alternator cables on the starter relay but once I'd figured and fixed that booboo, the rest of it did work first time. Add fuel tank, fuel, ignition key and starter button - nothing. It churned over and gave off a heady stink of unburnt fuel. Re-checked all connectors and did some quick, basic troubleshooting. Took the fuel tank off and just - but only just - dodged the resulting spray. So... definately not a fuel pump problem. Sat back and did some thinking; my gut feeling was that the HES had taken a hit from the short-circuit that had started the fire. Walked off and left it. That was about a month ago.

Today, armed with Bert's ignition troubleshooting guide, I was determined to get to the root cause of the problem. I got to the bit about testing the HES with an LED and fairly quickly realised that I could disconnect the HES plug and crank the engine rather than try and wave a feeler gauge at the HES to test it. I made up a small module with two 12v LEDs on it, plugged into the HES lead and applied power. One LED on, one LED off. Well... I suppose that the rotor could have come to rest with the cutout next to one of the HES. Cranking the engine soon disabused me of that notion. The LED that was on remained on. The LED that was off remained off. Switched LEDs, no change.

Bollox. Sometimes I really hate being right.


[Edit] Just got a replacement from a UK breakers on ebay for £39.99 (not Motorworks). I baulked a bit at the £14.99 shipping charge but needs must. I did think about just buying new HES from Germany but the price plus shipping was slightly north of the complete UK assembly.

Well, the 40-quid replacement was faulty, hence the other threads on whether the K1200 HES would fit. Plugged it in, no spark. Swapped it onto Low Flying Brick, no spark. No argument from the breakers who immediately swapped it for the K1200 unit. Changed the plug, plugged it into LFB and... no spark. The fuel pump did spin up, so one HES was okay. Down tools and just leave it alone - that was about a month ago. I was going to pull the new loom off Kostenlot last weekend and re-re-re-check it for errors, but the temperature took a nosedive and today we got 50mm of the cold white stuff.


So Kostenlot is still looking for its lost spark and LFB's HES plate is swinging in the breeze, waiting for the next unit to be tested.

I wasn't happy with it being the only uninsured bike in the garage, so as my bike insurance was due I rang Carole Nash to see how much it would cost to put on my existing policy. Fully comp, the cost was £0.00p. That's not a typo. £0.00p, just in case you thought it was still a typo Very Happy

An update... from a not too happy bunny. Earlier in the year I'd bought four new HES units from Sonnecy in Germany

http://www.hallsensors.de/CYHME56C.pdf

and very carefully replaced two sets of known-dead OEM sensors. Neither repaired plate worked. Having found an error in the new wiring loom (I'd wired up the temp sensor pins backwards i.e. pin E to pin A3 etc..) I assumed this was the source of the no spark problem and that I'd blown all four new sensor units. This is getting stupidly expensive. WTF is going on? So I made a new ignition sub-loom for Kostenlot, satisfied myself six times that it was absolutely right and mounted it on the bike. Meanwhile, I'd ordered another five HES units from Sonnecy (because five units was only €4 more than four units - total cost inclusing shipping was a little north of £80). They arrived within five days, which was a really pleasant surprise. Again, I exercised check, check and recheck while wiring them up. I also used miniature croc-clips as heatsinks to ensure that very little heat could get down the wires to the sensors themselves. They definately passed quality control, so I mounted them on Low Flying Brick to test them.

No spark.

Not even a tiny weeny hint of a spark.

Swapped LFB's original plate back in - no problem. Brum, brum.

Tried again. Same result. No surprise.

Put them on Kostenlot but got the result I expected.

So, based on s/h HES plates from BSK being only (!) £50 a throw, I put LFB's HES plate on Kostenlot.

Two big fat bright blue sparks from cylinders 1 and 2.

LFB fired up quite happily when it got its HES plate back.

So... I absolutely know that I have not errored in mounting or wiring up the replacement HES units on any of the three plates that I've overhauled. The conclusion is not nice; the CHYME56 HES is either not fit for purpose or I've managed to get a shedload of bad ones. Either way, that was almost £200 straight down the pan because you can't send them back after mounting them. If anyone actually wants the three unused ones, PM me because you can have the damn things for free to try it yourself. I get to call BSK in the morning.
