2010 Griso 1200 8V here... Starter issues like everyone else, tried everything, include MPH wiring. Finally replaced Starter/Solenoid with a Bosch Unit: 001 106 407 from Euro Moto Electrics. Problem solved. Starter motor was actually OK, Solenoid apparently F'ed.

This will be my Last Guzzi. I've never had this type problem in 40 years of riding motorcycles, and I don't have time to deal with it now. Especially since it's so hard to get parts from Piaggio. Guzzi should just give us a Kick Starter!

I am having the startus interruptus problem with my 2012 Stelvio NTX with 90,000 km on the clock. The battery is new and shows 12.8 volts at the battery terminals. However, there is only 10.4 volts at the starter solenoid and no startus. I've noticed that the headlights come on as soon as I press the starter button, and to eliminate the headlight draw, I removed the headlight relay and gained an additional volt at the starter solenoid. My question is: should the headlights come on when I press the starter button, or should they come on once the engine starts? Have I got an incorrect relay in my headlight circuit or some other problem? Perhaps this is normal and how everything is supposed to work. Thanks in advance for your answer. Len O

This is well documented and explained. Did you exert any effort and read the posts?

90,000 km and you never noticed how the lights work?

I’m confused and bewildered.

Full disclosure - my first post. I have recently applied the starter wiring fixes to both my Guzzis with great success. Both bikes would try to start yet act as though it had a weak battery (ie hesitate before cranking or trying unsuccessfully to crank). This began with my 2004 V11Sport Ballabio which went through a couple batteries, then I rebuilt the starter with a new solenoid. Both fixes would work for a little while, then regress back to weak starting. I kept the bike on a battery maintainer thinking there was a mysterious current drain, that only helped a little. The other bike is a 2012 Norge and there I also replaced the battery which only helped for a couple days. After reading this entire thread, I made the wiring fix to the Norge first as it is a simple one fused wire change. Wow. Problem solved. The V11 has a different wiring scheme which required a separate relay + fuse to be added, this of course has been discussed previously. The difference when starting was immediately, hugely better. I would guess that aside from delivering a better voltage to the solenoid, the lesser overall wiring resistance allows more power to the starter motor too.

OMG, come here and let me shake your hand Sir!

Now, if everyone that has a problem did this, things would be so much easier and successful for them all.

I tell people all the time that there are very few issues that are not already discussed and solved in detail. SEARCH is a powerful tool and your best friend when combined with reading! :)

Besides, nothing is more stimulating and fun, like interesting and intelligent questions which spring forth from a basic knowledge and understanding garnered from reading.

My 2017 V7III Racer is down for the count. Seems like "startus interrputus". Pushing the start button the first time I get a quick "chug" from the starter then, after that, only the relay under the tank clicks.
I replaced the starter relay, tried different batteries, took apart and cleaned and lubed the starter and solenoid, disassembled and cleaned the start and kill switches, cleaned and tightened bolted electrical connections on the battery and starter.
My wiring diagram (from the service manual) is illegible. I've searched and cant find the answer:
Which wire on the V7III gets cut for the bypass? The colors are different than the ones mentioned in this thread. I think it's still pin 5 but want to make sure.

You can’t find the answer because V7’s don’t have startus interuptus.

You have a different issue.

FYI: There is a high resolution color wiring diagram in the DOWNLOADS section, available to members who contribute to the site.

Everything you could possibly need is right here, but you have to contribute and then go get it.

Does the starter work when not in the bike, as in with no load? The Valeo starters are prone to failure.
