Left indicator turns itself on (1200 Sport)

Hi all,
My 1200 Sport has started randomly turning the left indicators on by itself.. Yesterday it was more of a flickering than the standard blinks.

It’s only ever the left side, and doesn’t seem to be any particular thing that triggers it. I’m not really sure where to look, it seems there isn’t a flasher relay - hope it’s not a dash issue. The flickering probably says wiring. Could it be the bar control/switch-
Cheers.

Hello Bill

From Carl Allison’s wiring diagram click here it appears that the indicators and switches connect directly into the dash. I would suggest that you check all of the connections in case something is badly connected or earthing where it shouldn’t. If nothing is obvious it would then be probably the switch or the dash.

Sorry I can’t be of more help, best wishes Chris

Yes the indicators are flashed by the dash. But i have never heard of this fault - most likely wiring contacts as you say. Before you worry about that check connectors as Chris says and clean any corrosion off contacts - especially bulbs and bulb holders

In the past I wore out my indicator switch and it would operate randomly and one side being worse.

I had a similar problem with my 1200 sport turning on the left indicator (I think) all by itself. It turned out to be a tiny ball bearing inside the switch that was rolling around and making contact with the left connections. As I recall the bearing was part of the push cancelling function of the switch and had broke free from it’s captivity. I managed to take it apart and put everything back where it belonged. I can’t remember what I did to make sure it didn’t come out again, but it must’ve involved doing something to the plastic that it was held in.

Thanks very much all!
The diagram is great vs the photocopy of the manual, cheers. I had a look at the indicators, they both look in excellent nick inside. The toggle switch feels smooth, positive both ways, I opened the control block but failed to see how to lift the half-round saddle that the switch gubbins lives under. Didn’t want to break anything so settled for a good lot of switch cleaner squirted in all small holes I could find.
Hopefully do a test ride tomorrow or day after, on the offchance it’s made any odds.
Thanks again all.

So I thought it might be fixed at first, did a few miles on various types of road, but it came back. I did suspect the vibes at certain fruity rpm’s might’ve been one trigger, so tested that out today and it happened. Though it’s not the only cause.
Think I’ll be handing it to a mechanic, as well as not knowing my way round the bike yet I’m madly short of time. At least it does feel more of a physical type of cause, than a PCB one (fingers crossed)

I recently had the same issue on my 1200 sport. The inside of the dash had rotted due to some cracks in the plastic. I sent mine to carmo electronics and they fixed it up (I believe they also apply a waterproof coating to the PCB). Fingers crossed it’s something physical instead though!

Thanks Tom - I found a few older posts mentioning indicators vs dash, but none detailed what the indicators were or weren’t doing.
I’m tempted to send it away for a check and get it coated anyway regardless of the fault cause, just to have it done and safeguarded.

Is the dash much bother to get at? Looks like the screen off, and tank off ?

cheers
Bill

You can remove the dash with the tank on.

Remove cockpit fairing

Remove headlight and rest on mudguard

Remove torx screws from under dash cover

You can unclip the dash plug and then 3 screws securing the dash.

Think that’s it :face_with_diagonal_mouth:

Cheers Brian! I’ll wangle some time and give it a coat of looking at over the weekend, ta.

I did split the dash apart myself too, there’s a bead of silicone sealant (or there was on mine anyway) that could make it tricky though. I think if you can confirm the switch is switching and there’s no wiring problems (so that the dash is the likely culprit) it’s probably not worth splitting the dash yourself as it will likely be brittle in places.

Cheers, I’ll be chasing the wiring and connectors and if needs be send the dash away whole - probably little point in me diving in there, plus as you say the risk to the unit isn’t worth taking.
