M620 malfunctioning speedo and odometer..help!

[AK ducati]

Yeah, the bike starts just fine and I'm able to ride it (at least I did a couple of days ago) even with the speedometer and tach display issue. I was going over the manual that DarkMonster620 sent-well just the pictures since it's in French and German  , but the section about the console has a couple of photographs that look somewhat like what's happening in my tach display on ignition. It starts going through a series of digits (I can give you the exact sequence tomorrow) like it's reformatting, and then goes to the temp display, and normal time display on toggling. ECU has never been flashed to kill the immobilizer. And I only have one black key, so hopefully that's not the issue...

When you suggest checking the pins in the connector to the gauges, are you referring to the single connection (with the wire bundle) that is connected to the back of the gauges?

Uuuuups!

Soooorry!!! Will loom for English/Italian one . . .

[Howie]

Yes, that one.  The fact that the bike starts means the ECU, gauges and key are all communicating.  This means part of the gauges are getting power or ground, but not all. The problem is either in the wiring or the gauges themselves.

Wiring schematic here  http://www.ducati.com/services/maintenance/index.do  at the end of the manual.

I'll look at the connector to the gauges today, and check the connecting pins. If they all look good, what would you suggest I follow up on next? Mechanical and electrical system ignoramus here, so any and all suggestions are highly valued! DarkMonster620, figured you'd accidentally sent the wrong manual 

[Howie]

Perhaps the next step should be qualified repair shop since replacing parts randomly gets expensive. 

[AK ducati]

I really wish that were an option. Unfortunately there's only a Honda place in town, and one independent place (if it hasn't closed down by now). So I'm it.

Update: So I wanted a second opinion on the battery under load testing-I had a hard time believing that the battery test showed it as good yesterday (I had also charged the battery up fully yesterday). My friends load-tester just now showed the battery was on the border of bad-weak under load. We also checked the bike charging system for the battery, and that showed as good.

So the next thing I'm going to try is to again charge the battery up fully tomorrow using a charger, and in the evening take it over to my friend and load-test it. If it still shows as bad-weak, I'm guessing that's at least part of the problem if not all. Also, Howie, I removed the console and checked the connector pins as you'd suggested. They all looked good, and I couldn't see any signs of corrosion anywhere.

[Howie]

A poor battery can make electronics go wonky beyond logic.  Don't pull your hair out until you know you are dealing with a good battery.

Update: Finally received a new battery and installed it. Turned the key and I still have the same problem. The odometer isn't working, with a display that reads "Total------", while the trip meter works, but resets itself to 0.0 everytime I switch off the ignition. The tach display window holds the time, but is still giving me a temperature read from 50C instead of showing "LO". And neither the speedometer or tachometer needle are doing the initial diagnostic sweep. Just went for a short ride, and everything else is working just fine, including the speedometer and tachometer. Now this is just getting frustrating.

I'd say the cluster is fuxxored.

[AK ducati]

If so, is it even possible for me to replace the instrument cluster, while holding on to my key? I unfortunately have only one black key  (not my fault, I bought the bike from the third owner.....), and it's not worth the expense taking (i.e. shipping), the bike to the nearest Ducati dealer in Anchorage.

[Speeddog]

Yes, send your ECU off to get the immobilizer disabled, then you can use any compatible cluster.

At that point, AFAIK, you can just get a blank key or two cut to match the one you've got.

[AK ducati]

There's hope!! Any suggestions as to where I can send the ECU to get the immobilizer disabled? I'm in Juneau, AK. Wonderful place to be for every motorcycle except for a Ducati.

Much appreciated. Thanks!
