Centauro issues, I have 'em!
« on: July 17, 2026, 09:04:13 PM »
'98 Centauro...ran fine until it didn't. It decided it would turn over, but not fire. The next time I tried, it turned a couple times, then decided to play dead. Now, it's alternating between playing dead and sometimes letting dash lights come on. I feel a click at the relay board, but only intermittently. I have a factory manual, but the wiring diagrams are missing. Can anyone point me to one? My mechanical skills are average, but I'm willing to try. I was in some Guzzi groups on FB, but they are keeping me in FB jail, for some reason. So, I can't ask there.

Those relays are always suspect. Get spares, even if the issue is something else.
Maybe from Dan at dpguzzi.com

Good judgement comes from experience.
And experience. That comes from poor judgement.

When I owned a Centauro, I was a member of this group: https://www.centauro-owners.com/

Well, all yay me and stuff! Thanks, guys, I'll see what I can accomplish from this. It may be a bit, but I'll check in with results.

Fun bike. Keep at it. What version do you have?

What was said before 100% things I would check. Also check your ground wire, and positive battery cable. A cable with bad solder can drive you nuts.

the cam phase sensor can go bad. Caused all kinds of stalling and non starting issues on my bike. Cheap part and an easy fix if that's your issue.
