Electrical Gremlins 2007 Norge

[mikebr]

My 2007 Norge has been having issues with the indicators and Mode switch not working then come right then stop working again, everything else on the switch gear works horn and high beam.
So today it stopped working again time to take the switch apart.
What a pain taking the indicator switch apart and having that small ball bearing bounce onto the floor.
Contacts looked good no corrosion sprayed it with Deoxit found the ball bearing and put it back together still not working.
Pulled the dash apart sprayed the multipin plug and still the same.
Time to get serious pulled the tank off and found one connector at the front of the airbox had a bit of green oxide so cleaned that up but all other connectors looked good and again still no go.
Now a service display is showing and still can not access the mode display or use the indicators so any suggestions on what the next steps I can do to fix this problems, thanks.

Mine's an '07 and every time I thought of something as I read on, you'd already done it.
Do you know someone who has the same left switchblock to exchange and test ?

[pete roper]

Sounds like a dash issue.

I wish HE hadn't said that...

I assume that you cleaned the battery connections well, my 09 Norge gets weird electrical gremlins whenever there is any corrosion or oxidation at the battery terminal.  Not trying to be condescending, just saying...

The button for my Griso dash is very difficult to use, sometimes I have to push it dozens of times for it to have effect for example just to reset one of the trips might take a minute but it usually it gets easier with use.
On the other hand the Mode switch works well, it always changes the display,
I suspect the button has a dirty contact, microprocessors like their inputs to be crisp, no half measures.

I have toyed with the idea of opening the dash and connecting a reed switch in parallel. Reed switches have their contacts sealed inside a glass envelope, a small magnet on the outside of the case will always result in a closed contact.

Same here will play around more with connectors and see what happens.

Pulled the battery connection, positive did have some corrosion around it so cleaned that but haven't checked the negative terminal yet.

Roy, seems strange that both switches are playing up at the same time the indicator switch is nice and clean but still not working.

[Kiwi_Roy]

The switch that's difficult is the push-button at the lower front of the bar, Its a job I will save for winter.
I just thought it might be a common problem, that's why I shared

Doesn't sound good..

Indeed,
The Left and Right indicator lamps are driven from the Dash (4 outputs)
34/35/36/37
The L/R switch turns on the dash inputs 2/12

Does your dash show any signs of condensation, is the bike left outside at all?

The Norge was in a storage container parked beside my Griso until my garage was built no condensation in the dash pressing the 4 way flashers all the indicators work Griso has no problems.

While Roy will be able to confirm this the fact that the hazards work would, I think, indicate it's unlikely to be dash related then. If you can find a partner in crime with the same bike, (Breva/Sport might do as well but the pin out might be different.) you could try swapping switchgear to see if it's switch related.

Pete is right, the 4 way flasher input is a separate input pin 14.

Since there are two switches, one for Left, one for Right I would expect it to be the common wire to both switches, it's not likely that both would fail at the same time.
The Griso doesn't have as many inputs but I assume both dashes and the pinouts are the same, Pete can confirm that.

You could probably ohm out each switch to the respective pin 2 or 12 of the grey connector but there's also another connector (1) in between,
Note the red wire along the bottom of the switch, that appears to be the common feed to the L/R contacts.

[pete roper]

Norge and Griso dashes are different, as are the switchblocks and their operations.

So much for that idea then, I thought they might have shared some pins.
Here is a explanation of the switch, I tried to make it simple but I'm no teacher, that's for sure.
The switch can do several things at once but just concentrate on one at the time.

I notice there's another input SCROLL and CODE and TIME that seems to share the same feed, do they work?


If you can find connector (1) you should be able to test everything from there.

On further thought the wire i called Hot may in fact be grounded, its more common to pull a microprocessor input to ground
to turn the input ON in which case the inputs would be 5 Volts normally and zero when turned ON

Good Luck

[Kiwi_Roy]

I made a bit of a mess of my last post, I took another look and it seems the dash inputs are grounded from pin18 of the dash via the common brown wire, perhaps there's a loose ground input to the dash, anyway you should be able to check the brown wire's connected to chassis with your multimeter.
The LED on the 4 way flasher switch (red question mark) should also be turned on indicating it's grounded



I suspect it's grounded via pin 18 just to make it more convenient, all wires in the same loom.

I'm pretty sure you can exercise the different dash inputs by poking a grounded wire into the bottom half of connector (1) however I would do that through a resistor like 1K just to limit any accidental short circuit current.

Interesting that the 4 way flashers still work as the switch for those is grounded from the same dash pin but that could have been a co-incidence.

There are a few other inputs that rely on a good ground to the brown wire
Heated handgrip switch, Fuel Level sensor, Air Temperature sensor, some of these will try to pull the wire high rather than low.



Showing how you can test the inputs to Dash from the socket where the switch plugs in.

I thought it was a good way to cut the pool of possible causes in half..

Update:  I thought I had the plugs for the left hand switch but they were hiding in front of the ECM and what a job getting them out sprayed them with deoxit and got the indicators working again but the mode switch is playing up still.
Before when the mode switch didn't work the indicators would not work either.
Finally got the mode switch to get me into diagnostics and took a couple of photos before it played up again.
The DSB showed a x beside 05 on A And M.
The ECU showed a x beside 16 ACT.
Deleted all errors and the service icon then reset the clock then exit.
Anyway the service icon came back and at this time cannot get back into diagnostics to see what active.

Researched the codes that I had tank and air box were disconnected so plugged them in all good now so looks like dirty contacts on plug by ECM.
Thanks everyone for their help hopefully no more problems.

No other Guzzi's where I live.

[Kiwi_Roy]

By the Mode switch, do you mean the button at the front of the grip, operated by the forefinger, I suspect the one on my Griso is not making good contact, it sometimes
takes a while for it to register, a winter project.

[pete roper]

Different switch cluster. It uses a central toggle switch, no button.
