Norge problems, AGAIN!

[Bison]

Dear People,
Did over 800 miles on my "fixed" 2007 Norge. The Ducati ECU with the Norge map and EEPROM downloaded, bike running better than it ever has. This morning, press the start button, churn churn, broom, runs for about 2 seconds then cuts out, nothing, I mean nothing, no dash, no lights, zilch. Check battery, 13.02V, main fuse, take off ground cable, leave for a while, put it back on, nothing. earths great, connections great, new battery. When I say nothing, no pump working, no clicks or noises when battery connected up, the whole bike is completely dead. The only thing I noticed was the fuel level gauge was working, with the ignition off!, after disconnecting the battery a few times it is now not working either, that is the only thing that showed life. All fuses ok, power to the fuse box with the small fuses, power to the main fuses. Tomorrow I'll pull the fairing and check the dash plug connections. I have the original ECU, the only thing wrong with it is the start button doesn't work, I'll fit that, and if I then have power then its the ecu fried again I would think?. I have a brand new ECU bought from a company in Holland, but I'll be loath to fit it until I find out what's going on.
It did exactly this when the original Guzzi ECU was fitted, fired then cut out, but that time after a few minutes with the ignition on all the lights on the dash miraculously came on again.
Any ideas before I throw it off a cliff?.
Alan.

  Buy an older motorcycle with points and carburetors. You'll be rid of the electronic Hocus Pocus.

That sounds like my usual answer 
I don't have a Norge, just EV and carb. Spot. But check relays. Always keep a spare.
Sometimes just unpluggng them, then replug them works, cleans the connection I guess.
Good Luck

My 1200s did something like that, it was multipin connector going into the ECU. I cleaned the pins with a silicon spray and a tooth brush then secured the wire bundle where it curves into the connector with a few zip ties and it hasn't been trouble since.
  I isolated the problem by wiggling and giggling the harness while trying to start it.

You battery should be good, but.....can you hook up another battery to it with jumper cables or use a jump box just for a test?

I would have thought a fuse at least or maybe a relay, but all seem good and IIRR you went through them previously.

Could it be the key switch?

Obviously you have turned the key on and off a few times, have you wiggled it or held it every direction while turning it to the on position? Had an old truck that the switch failed. If you just trued the key into position, not go. But I noticed just before it's position, I would get, and then loose power.

You would need to look at the wiring diagram to see where power goes in and out of the switch. There should be a connector about a foot from the switch I think. I would try to access the connector. I think you would be able to use a muli meter probe to slip down the side of the wire into the connector. If the probe won't fit, something like a sewing needle or paper clip might slide in. Test both sides of the connector. Unplug the connector and just test the battery side of it if the above does not tell you anything to make sure your at least getting power to the connector.

If you get power from the battery to the connector or all the way to the switch, but no power out of the switch, there's your problem.

Electrics, damn frustrating!!!!!!!!

Isn’t that from the year with the dash problem where they died and bike won’t run. Too bad you don’t have a spare dash. For starters I’d check the plug to dash as you said you would.

Sounds like possible Startus Interuptus
Is the Number plate light ON, how bright?
The first thing I want to know on a fuel injected bike is the injection relay energized?
Its energized by the ECU first of all to prime the pump while cranking, its purely a timing function while cranking
Once the engine fires up pulses from the crank position sensor tells the ECU to power up the pump again so it turns on the injection relay again. to power up the fuel pump and ignition
Looking at the injection relay pin 3 you will see a Red /brown wire that powers up the injectors, coils and the fuel pump, you need to hang a small bulb on there so you can tell the status

Most vexing for you 

Do the above, but then I think I'd  be ringing out every circuit to check for continuity between connections.....as in un plug and go pin to pin

Good luck , I hate chasing electrical anomalies

Hi,
No power anywhere, no lights at all.
According to the wiring diagram there should be a direct feed of 12v from the main fuse to the switch, with the switch unplugged I'm getting tiny voltages to 5 of the pins, no idea why. The wires from the main fuse are very large diameter, so somewhere in the loom they reduce to the switch size, if only I could find out where

[tris]

Do the 3 small fuses C, D & E have 12v on them?

If yes probe 11, 20 and 22 on the connectors to the ecu for 12v

If yes then the break is down the loom towards the ign switch.

I think it helps to break things into bite sized pieces of you can

[Bison]

OK, fixed, two problems. The previous owner fitted 30 amp strip fuses, which I have checked on numerous occasions, 12.8v or more either side, but looking closely the connector on the loom side looked slightly swollen, looked closer, it appeared it had been hot, slight discolouration of the insulation, checked and checked again, 12.8v either side. Stripped the heat shrink off the connector and it was apparent it had been overheating, , put a load on it and it started getting hot, bad solder joint. Stripped cleaned and re soldered and I had power to the dash. Next thing was no starter button, swapped relays around  it started. Went for a ride, warning triangle came up, sure as fate, switched the engine off and it wouldn't, respond to the start button. Had a close look at the relay connection , when I pushed in the relay to the plastic connector it had displaced on of the metal connectors, you could just see it poking out of the plastic, it was sometimes making the circuit, sometimes not. Pushed it home with a screwdriver. All is well, until the next wiring problem, Luigi and his electrics!.
I hope this might shed light for anyone with a similar problem. Alan.

Jeez Bison.
If you keep this bike, you will be the sole source of all knowlege and diagnostic skills.
Well done Sir…!
More than your skills, I applaud your stoic and good natured approach to perplexing and vexing issues…..
You would have been good to have around during the Flight of the Phoenix…..You’d have the bastard up and going before lunch.

[Tom H]

Hopefully you have fixed all your issues!!

Yes, and trade electric problems for clogged jets and burned out condensers!

Great work!  But it seems unfair to blame Luigi. More the fault of a ham-fisted previous owner, I'd guess.

Once upon a time in a land far far way, I had cause to remove the front fairing mount from my ‘07 Norge, it had broken at a point where 2 tubes meet and concentrate flexing and subsequently broke. I removed it and fitted a wrap around triangular gusset and TIG’d it back on,
No worries, but…
Some time later I had shut the bike off and upon returning and turning the key, I encountered exactly the same issue as you….
Nothing !
The bike was as dead as a maggot and no amount of buggerising around could find the issue. My mate came up and collected me in the Hilux.
However, subsequent investigation revealed that when I was wrenching around on the wiring loom to reinstall the fairing mount, I had broken off the main 12V feed to the switch.
While waiting for my mate to come up from Victoria 12 hrs away, I removed the front fairing and went looking. If I’d removed the cover over the back of the switch, I’d have seen the dislodged wire and could have heated a piece if fencing wire in the fire and re attached it.
Anyway point is..
Check that…

Great forum that's helped me so much with my 07 Norge!

I just recovered my totally dead bike, blinked out while riding and blowing the 30 AMP main fuse, with smoke!

It was a clumbsy factory 4" extension wire under the airbox to the alternator that was pinched against the braided oil lines for years and wore thru, causing the short and electrically punched a small hole in the braided oil line causing a leak. Could have, should have been a fire I think.

Simple shorted out wire in my case, thanks for being here and the support, I love my 07 Norge, that beautiful bitch.

Well said, could not have put it better…
There’s not much that you don’t know.
Well done !


PS
ALWAYS…Secure the tank if you have it perched like that…
