Fazer 600 S2 display problem

(1/2) > >>

Marc M:
Hi folks. Looking for some help. My display goes on and off randomly. I still have N light and indicator lights, but no revs or digi display. It goes on and off on its own accord. Even sitting still with ignition on. It doesn’t get worse or better during riding. I’ve checked the connections under the tank and seat, I’ve changed all fuses, I’ve removed and opened the display unit. Even wiggling wires around doesn’t make a difference. All the connections are in good shape, and all the wiring looks in good shape too. When the display is on it all works fine, but then it goes off and on again. I recently replaced the battery and still no joy.
Does anyone have any idea what I can check next? I’m at a real loose end with this. I kinda thought maybe an earth point issue, but I can’t find anywhere where there’s wires attaching to frame for ground.
I’d really appreciate any help or advice.
Many thanks in advance.
Marc.

If you've got the S2, you should be able to open the instrument cluster by undoing a few screws (with the S1 you have to cut it open!)

Check the connections inside and make sure the LCD panel is seated properly and secure.

Thanks for the info Grahamm 👍
I’ve already opened the display with the screws. All looked secure and clean. I gave it a wee spray of contact cleaner and left it to dry out for a bit. The rev counter isn’t working either.
I’m pretty sure it’s probably something stupid like a dodgy connection, or wire, bit I just can’t gain enough access to check all the full wires in the loom.
My worry is, could it maybe be rectifier or stater?
I’m not really confident when it comes to bike mechanics and especially when it comes to electrics, so I’m really just trying different connectors etc.
It started to happen when my previous battery went flat, but now I’ve got new battery it’s still doing it.
Thanks again mate. 👍

Grahamm:
The only other thing I can think of is to use a multimeter to check the continuity of the wires that lead from the cluster to the plugs at the front left of the fuel tank, then back through the loom to the sensors and ECU.

It's possible that you've just got a loose wire or a dodgy ground somewhere.

Marc M:
Thanks again for your advice and info Grahamm 👍
I’ve stripped and cleaned the main connectors into the starter solenoid, even though they were very clean anyway. Had another go at wiggling different cables and parts of the loom. Still no joy :'(
I don’t have a multimeter and I’ve no clue how to use one, plus I’m not too keen on messing too much with electrics, except for basic stuff. I really should get my head round using a multimeter.
So today I decided to throw in the towel, and took it to my local bike garage. Initial thoughts were ignition cables somewhere, but given that the bike runs perfectly and the N light works as well as indicators and other lights, he says it might be a fault in the PCB inside the display unit itself. Weird though, cos when it’s on it works fine, but then goes off again. So it may very well be a resistor on the PCB. So I’ve booked it in for them to sort it, but unfortunately they’re mega busy, so I need to wait for 5 weeks before taking it in.
Hopefully it’ll rain for the next 5 weeks, then I won’t feel so bad.  :D
I can still use the bike no problem, just need to be vigilant with fuel and speed.


Thanks again.
