Tip over switch/bank angle sensor

Where the fuck does this particularly recalcitrant piece of electrickery hide on an 1100. Hit start button and silence ensues. Guzzidiag says"Tipp over switch active". Ive had this before and bridging the clutch switch fixed. It happened yesterday and after pulling the 30 Amp fuses for 20 seconds it started. But not tofuckenday. All fuses good. Sidestand and clutch switches bridged for the exercise. After stopping the bike last night I noticed my left hand bar end weight was a tad loose,these are not standard and are the expanding inner type so I loosened its screw and gave it a tap with a soft hammer to drive it home and then tightened its screw. Fixed. Im tempted to give the other handlebar a tap with my softhammer .....

Stay calm Charlie , put the hammer down , the electrical components pic in the manual should point you to it .
Item 6. Under the right side near the relays ?

Cheers Ron , I am in the process of removing the tail piece to gain access to the relays and hopefully the tip over switch.
I pulled the wire connector to the start switch, put my multimeter on the red and yellow wire and the blue wire , these go to the start button, and got the missus to press the start button and the meter did fuck all. I had sprayed the switch with contact cleaner so the switch seems to be the culprit. Is there another way I can test this ?
On the bright side I now have a laminated colour A2 copy of Carl Allisons wiring diagram

Open the switch and bridge it. If the bike turns over, problem found.

I'd never found that switch. I was aware of it on other models but I've never had need to look for it on the GRiSO and also thought perhaps it had been deleted or never employed.

Live and learn Eh?

My great bag o'shite never stops running when I throw it on its side! Perhaps my switch is broken? (doubtful!)

The tip over switch is located in front and slightly above the ECU, near the steering head.

It's mounted onto the frame in a rubber holder.

If you remove the one of side panels you will see it near the ECU.

This sensor correctly positioned and with the engine running is open contact (62K ohms).

If the bike falls over, the sensor closes its contact (0 Ohms).

Will dropping the bike damage the tip over switch? I've had no start issues with the GRiSO but I always attributed that to making bad contacts with battery?

I don’t think dropping the bike is going to damage the tip over sensor.  You can check this by temporarily disconnecting it, the bike will still run.

If you have ‘no start’ issues, this is known problem and you can search this forum for that.

You should also check your battery voltage (too low and it won’t start) and also the earth lead connection behind the starter cover.

I had an intermittent ‘no start’ problem on my 1100, which I traced to a faulty electrical contact in a connector from the starter button.

Charlie, the fall over cut out is a ball bearing in a 'V' shaped pair of contacts. Unless you do something like hit it with a fucking great hammer it won't be a problem.

Last time I had guzzidiag open and my bike on its sidestand, I could swear tip over switch was also set to active and it would start. Maybe someone else can chime in, but I came to the conclusion that it was a matter of how vocabulary, that the tip over is active if the bike is still rubber side down.

the reading is changed in guzzidiag on the tipover switch because it was not clear. So be shure to have 0.47 guzzidiag.

If all is ok, you should have the message in Gd "start possible".

If you drop the bike it takes 15 minutes before it is ok again to start. And if the tippover is really broken, you can disconnect it to come home.

Yes. 15 minutes of feeling like a dope while you wait for the bike to start again. I know.

15 minutes of feeling like a dope is probably a good thing! Just because it will start, doesn't mean you should ride it.

Ditto. But then you have time to look for that stupid-expensive little rubber "Guzzi" oval plug thing that covers the allen bolt in the valve cover that popped off. Natch' you won't find it. Then you'll look up the price on a replacement and swear out loud when you see what they want for them .

I dropped my 1100 at zero speed waiting for the ferry at Dawson City.
It wouldn't turn over so I hot wired the solenoid, the shaking must have reset the switch.

In my last remaining brain cell, I have recollection that there is a time delay in the ECU when the tip over switch is activated.  So the engine will not start immediately.

Or am I imagining all this?

There may well be but I had hot wired the starter in around 5 minutes, perhaps starting caused it to bypass the time delay.
Would be interesting to test that theory.

Dang Kiwi_Roy,

Dawson City is a fair distance from your home port. You have my respect.

Yes I went to the Arctic Circle up the Dempster then doodled down past Salt lake City for a Not A Rally

Somewhere in the same year I did a quick trip back to NZ and borrowed a bike from Kiwi Dave to visit family down island

I'm glad I did that before this Chinese Bat virus raised its head, can't see me going anywhere this year.
