nope, soz, still here mate. if I get that pissed off I normally sign off with "un-notified, good luck!"
in this case it is simply too amusing too let go. I mean the guys has been advised / told several times. he wants the help but isnt acting on it. there can only be surely 4 root cause failure modes here, in order of my evaluation (based on likelyhood, cost and complexity to diagnose...)
1. TPS
2. ICU
3. Clocks
4. wiring
1. TPS adjusts voltage fed to the ICU so the return volts to the clocks can and will vary if there is a problem; without knowing every single failure mode of a TPS/ICU combination and the corresponding voltage routed to the clocks, one cannot assert with confidence that the 5K problem is not the TPS, even if it is disconnected and the clock still reads 5K, you dont know what the TPS/ICU has caused, that in turn has led to the anomalous error if indeed the error is anomalous? I suspect however that the ICU is a simple CDI unit ?? but have not seen a diagram of the fazer 600 ICU internals
So all can be done simply and relatively cheaply using a breaker part or something , is to replace the TPS and reset the system. This is the easiest and quickest fix, and has worked before on a 5K error I was working on.
2. If the TPS fix doesnt work then a simple swap out of the ICU is called for; you can pick one up off fleabay cheap as chips:
http://www.ebay.co.uk/sch/i.html?_kw=yamaha+fazer+600+ignition+unitThe OP may wish to try this first (than the TPS) but I've never heard of an ICU fail - for sure they do - I just never heard of one since 1989 hence the TPS suggestion from me. So then the OP has to sell the ICU and I dont hear much call for ICUs but plenty of demand for TPSs !!
3. If the TPS nor ICU fix solve the problem, then we're looking at the clocks or wiring; clocks may be providing erroneous values. The clocks can be tested on a bench with a power supply with a selectable voltage output; the tacho works on volts and this can easily be driven; however, the OP would need to remove the tacho, get a selectable power supply, and do some bench testing. Even then, if the clocks are in error, then he'd still have to buy a replacement. Hence the TPS and ICU fixes came first above; cheaper and easier to diagnose.
3. If the TPS, ICU and clocks hasnt fixed the issue, then its down to wiring. To strip the bike and trace the wiring through all the looms and check all wires. Good luck!
so there you are, an explanation as requested.
