M750 hesitant start button

[tctopcat]

Hi

I've recently bought a 2001 750 which has the problem of the start button not always turning the engine.

At the moment you need to press it 5/6 times before it responds.

The bike is fitted with a Ducati alarm/immobiliser if that makes any difference?

Any advice much appreciated...

Also... Does anyone know how I can add a pic of my beauty to my profile?

Thanks

Tom :tgoe:

Had exactly the same problem with mine. Turned out to be the side stand switch relay playing up intermittently (that took some finding out I can tell you). I shorted mine out and it's been fine ever since

Take the switch gear apart and clean it all up with contact cleaner or wd40. Also as stated above check the side stand kill switch thingy.

Also worth checking the wires going to the starter solenoid are connected properly (they can come loose easily and are a pain to get at). There's a switch built into the side stand (I've had one of them go wrong too) but more likely the relay if you're not moving the side stand between attempts to start.

Worth checking the battery if none of the above, and possibly the wiring around the headstock (again unlikely if you're not moving the bars around between attempts to start).

Otherwise water or dirt in the handlebar switch.

By the way, the wiring diagram is in the back of the handbook (the Haynes manual doesn't have the wiring diagrams for the later models).

Bet it's the relay...

Hi, I have got a 2000 M750 and the same thing happened to me two weeks after I got the bike! The ignition would be on and all lights would come on, but when I pressed the starter button there was nothing. The lights did not go dim or anything, it just did nothing.

After spending hours checking bits of the bike at random, my problem was the stand switch relay (rele sicurezze). I would recommend checking the easy things (battery, switches etc.) before taking anything apart. I got hold of the wiring diagram and worked through the various bits on the bike that would prevent it from starting.

So, to check the stand switch is working OK just find the connector stick a continuity tester over it and make sure continuity is broken and made as you operate the switch. Do the same for the kill switch, gear switch and of course the fuse (second one from the top ot the fusebox). If they work OK, try removing the relay and bridging the connections. Thats how I found out it was the relay on mine. This is easy to do and to dont need take anything apart.

Hope this helps, let us know how you get on.

Had this on my 900 - two wires snapped in the spur off the loom by the headstock, killing the 12v feed the to the button and starter solenoid. Did a spliced & insulated repair to both and it's been fine ever since..... touch wood. The loom had been badly routed/cable tied to to headlamp support at the factory, and was being constantly stretched on full lock to the point where it let go.

Thanks for all the advice... will get to work on her over the weekend and check all the above in the hope that I can fix it and silence all my jap bike mates who are now laughing at my expense and saying things like I told you ducati electrics were rubbish... fact is the grin she gives once she does get going is worth all the torment!!! thanks again guys.

Fiver says it's the relay...

Once you get her running again you wont be able to hear your mates on their Jap bikes when you open her up :cool: I had exactly the same comments when I bought mine, and this was made worse because my relay played up within two weeks of buying the bike!
