Heya guys, Happy Easter!
Have run into a CHEC problem display with intermittent dial sweep recently. A while back coming back from a wet weekend away going along the highway the dials would start sweeping intermittently and display would drop off. The bike was fine though, continues to run no problems. I suspected some water ingress into the side-stand switch, but once home I forgot about it given riding season was off.
Since then the speedo has been displaying crazy numbers, fluctuating all over the place. Bought a used speedo sensor and that has appeared to fix that problem, so not sure if related.
Now, however, when switching ignition on I get a permanent CHEC display, the pump primes up as expected and it starts and runs fine, going straight into fast idle as expected when cold and then settling down. But while idling like this I get intermittent dial sweep and occasionally the FI light pops on as well.
I checked the side-stand switch and getting right voltage one way and fully open the other, so I shorted that out just for the hell of it to eliminate, but no change.
I have pulled apart fuse box and disconnected connections on left-hand side and cleaned etc, but still no joy.
When the sweep occurs, the clock resets to 01.00 as if the battery has been disconnected for a moment, but bike continues to run.
I'm wondering now whether its some weirld loose or dodgy connection to the clocks.
Just another note, if I switch ingnition on but not start bike, I can hear the pump prime and then some other noise (actuator?) and its during these noisy times, that the sweeps and FI light occur. If I wait till noises have stopped, the dials do not sweep, so maybe related. However the CHEC display stays on all the time no matter what the status is.
Any ideas guys?
many thanks

First checks should be headlight off and check clean the connectors behind the headlight
And the check clean the big white multi plug behind the lefthand side penel.
Hopefully that will remove any water trapped in the plugs .
:cheers:
Further checks you can make:
- clutch switch (unlikely, but always worth checking, as they can go)
- the big grey plug under the LH side panel - pull apart, wash out with contact cleaner and re-assemble (plug to ECU)
- check earths all clean and good
- kill switch - again switch off, clean out with contact cleaner
- all plugs within the headlight
- and it also may be worth pulling out the ECU itself. Going back some years (on the old org), a few members had problems where water got into (or was surrounding) the ECU itself - they took out the ECU, dried it off overnight in the airing cupboard re-installed and all was good.
Thanks guys, have done all those things with no luck. However something has changed, it appears the clocks have failed entirely now :( ... the backlights work, but everything else is unresponsive and no readout at all on the LCD's
Prior to this, I took it for a ride to get petrol and all the way CHEC was showing and FUEL and TIME showed fine. Same on way back, then after shutting off, the needles both stayed fixed at the 10 o'clock mark. Turn on and off a few times and no change.
Interestingly the bike starts, runs and rides fine, so I think we can be confident that the PCB in the clock housing has failed sadly.
The cost for a new one from dealers is crazy, and I haven't been able to find one from wreckers, do you know of any over your way I could hunt one down?
Many thanks

Hmm not good. Unusual for the PCB to go but always possible I guess.
You might try this test to see if the needles work http://gsx1400owners.org/forum/index.php?topic=240.0
Given you are down under though, I'll defer to those forum members there to advise on a replacement board - other option is to fit a set of aftermarket clocks
@Tony Nitrous did that on his.
Perhaps put a "Wanted" ad in the Down Under section of this forum.
What model 14 incidentally, as clocks for the K2-K4 are different to those for the K5-K7/8
This will be the permanent +ve wire I think causing this fault.
Perm +12 volt in the small plug.
Many thanks again team 1400, appreciate the insights.
thanks indeed for the pinouts Froudy and links to the testing there Barmy, will have a crack and report back asap.
Cheers
Youre in good hands mate, trust these Pommys, theyre good. :)
Thanks guys, tested the pinouts at the plugs and right down to board level. All voltages and earths are there, but still no sweep or LCD displays. The indicators, oil light, hi beam, hazard etc all there and working. Backlights all working.
It looks like one side of the PCB that receives sensor signals necessary for FUEL, ODO, GEAR POSITION, SPEED etc has failed I'm assuming.
The rest of the bike runs and operates fine, so I'm guessing the ECM is fine. I do have a 1250 bandit set of clocks available, but pligs are different.
May just have to wait till a spare cluster comes up from the wreckers/breakers.
Thanks again guys, appreciate the help.
Cheers

@squizzy there is one more check you can do. Take out the battery, lift out the ECU and take off the plug (or plugs, depending on which model 14 you have) and give the contacts both on th eplugs and the ECU a good cleaning with some contact cleaner. A real outside possibility is that it may be a corroded pin on the ECU.
But it does sound like part of your PCB has failed. Very odd.
What model 14 do you have? Boards may be rarer then hen's teeth down under, but they do come up ocassionally on eBay in the UK, so we can keep a watch out for you. Also, if you pm Thommohawk in the UK, its possible he may have a spare PCB (can't be sure - and he hardly gets on here these days).
