Title: Bike won´t start after cutting wires from dashboard.. No immobilizer on the bike
Post by: jooohoo on May 29, 2013, 03:34:27 PM
Guys, i need some help now.

The bike is a 01 M900, which i believe is without immobilizer. The Ducati garage also confirmed it has not immobilizer, and i do not have the 2 black and 1 red key. So i feel quite sure of it has NOT immobilizer, since i have just 2 normal "old" ducati keys.

I have to mention that everything worked fine before. I had no problems earlier. But it came now after i cut the wires that connects to the dashboard, since i have plans to install a Motogadget chronoclassic speedo. Not sure why i tried to start the bike when the wires was cut, but maybe I just wanted to hear it roar before i quit for the day ;) So right now the bike won't start.

I connected all the wires back on to the oem dashboard, and to confirm that all the electric works:
lights, signal turn lights, break light, horn, neutral light, fuel light.. yeah every thing seems to work on the dashboard. But when i turn the key, and press start, it makes the normal starting sound when the gauge pin goes all the way and back. Which is strange since the pins actually don't go back and fourth. Never done that, but still have the same sound. Anyway this sound comes more from the fuel pump area.
The sound is also when i press the kill switch on and off.

But since the sound is from the fuel pump, I wonder if there are some problems with the fuel pump. I read some members experienced problem that the fuel pump wires got loose.. could the wiggle loose after raising the tank up and down?

I tried to eliminate the problems after reading several posts. Like kick stand problem..I don't have any mod on my kickstand yet, and the bike is on rear stand. So it's definitively not any issues with the kickstand.

Other issues that are mentioned on forums are clicking noise when start button is pushed. I don't have any clicking noise..So i not sure if that is a good or bad thing. But could it be any issue with the starting relay? I read about that some had similar problems and it was the solenoid that was the problem. I have not checked that yet.. Again, the bike worked fine just hours before.

It's not the battery, since i checked it and it shows 12V... but i put a charge on it tonight just to be sure.
There has been no signals that my battery was to low that i had any starting problem. So i don't believe its the battery.

So i need some help brothers, what could this be? Or is it just that the bike has an immoblizer, but since its a 01 model, it has no red key and use old ducati keys? I have never heard about that before.

Advise and experience from you guys is appreciated:)

Does it crank, or is nothing happening?

Did you check fuses?

UPDATE:

Nothing happens, no sounds or crank. Fuses are checked and battery is fully charged.

I checked the solenoid yesterday. I took it off, and connected to a charger to replicate like it was connected to a battery. It worked and its transmitting electric signals. I also heard the click noise that often is mentioned.
So i think the solenoid is working?

I also measure if there was any problem with connection of the starter button / kill switch. Result is that the wires are good. The button gives signal and wires sends out.
But i realized that the connection from starter /kill switch, the one that is situated on right headlight clamp. The electric signal ends there. Which means that the solenoid do not get juice and therefor not start or no response.

At least i think this is the reason. Anyone that experience the same?

Often times the small 2 wire connector on the solenoid doesn't make good contact in the solenoid.

Try reinstalling and making sure that connector is seated properly.

I know this is a touchy topic but I'm always wondering how many of these bikes are stolen with these issues.
No red keys, no immobilizer, dashboard problems...
I guess we'll never know.
'01 M900 did not have an immobilizer, no stupid red keys, and typically no issues with instruments other than an occasional screw that would fall out of the face.

I believe the S4 had it in '01 and all models had them starting in '02.

They also had steel gas tanks.

Aren't antiques great. ;D

there I go with my ignorance again.
But Nate,
Surely you do occasionally see posts about that make you suspicious????
That someone is a second owner and doesn't have a red key?

Not really suspicious.

A bike with no keys is suspicious. ;)

Funny that you asked about that. 3 year ago i had my two monsters tried to get stolen, but the immobilizer stopped them. When i went to my garage, both of them was vandalized because of the various attempts to start the bikes.

Good for me that they did not get taken, If i had older models it think the bikes would be gone.

I going to check the small wires to the solenoid tomorrow. Maybe its simple malfunction on the wires. I did check the solenoid, if it transmitted. And i have already ordered a new solenoid just in case, so gonna try that.

What i think it may be is the wires from start button down to the connection which is located next to the headlight. I have been on a lowering headlight mod, so maybe the connection is broken after taking on and off the start button wire connector..

The wires inside the harness can break where they pass around the steering head also.

If you don't find it externally that would be the next place to look.

This happened to me last year on my 2000 M900ie; I was surprised.

Also, I have had the connector on the solenoid come slightly loose after working on the bike and that took me a few minutes to figure out since everything looked connected.
Good luck.

I've had that happen as well blue.....mine took a little longer as I started tracing the problem from the start switch to starter relay.

Mind tho I was showing my son how to trace a wiring diagram and use a multimeter.

I have been looking today into the wires from start switch to relay. Found out that it must be the connection that is bad, because when i move on the wires from starter button, it makes the kill switch to go on and off. At least the sound is the same as you turn the kill switch on and off.

So seems like i know some sort of what is the problem. Now i need to find out where the connection is broken, and how to fix it  Hopefully i´m on right track here.

OzzyRob: How did you fix the problem?

I plugged the connector back in.

Update:
Found the problem. I manage to detect the error after using an elimination method. Anyway there was a broken wire, almost ripped off. The wire is located inside the main electric harness next to the steering head.
Need to get some supplies and gonna fix it tomorrow.

that's quite common.

Update:
Problem not solved. I've manage to connect the broken wire and made the bike start. Thought I solved the problem, but when I test started after setting up the front.. Light, speedo etc. the bike was dead. I still think it has to be problem with the start button and the wires down to the solenoid. So I have to dig in more to see if there are other bad connection to the wire.

In my start/kill motor switch, I had a tiny wire become unsoldered from the copper contact plate.  I didn't realize it until I took it completely apart.

Thanks for the advise mate, I would check the switch yet again.

Found the problem. It was another old wire that was almost torn. The wire goes down to the solenoid, and the error was down inside the main electric harness. Kind of pain in the A to find, but the bike is now starting again:)

it's always nice when you find a problem.
