This isn’t specific to that machine, I haven’t ever worked on one, but from general OHV mechanic troubleshooting.
1. Start with/at the battery. Make sure the ground is tight on both ends, positive is tight, and ideally try it with another battery. They can measure good with a volt meter but have a bad cell inside o they conk out with any load.
2. A lot of ATV’s and motorcycles have a main fuse on the starter solenoid, separate from anything in the fuse block. It’s the next thing to check if everything is dead with the key on.
3. When you say everything is “metering good” what exactly do you mean? You’ve verified it’s getting 12v into the key switch, and 12v out when it’s in the “on” position?
If so, it sounds like you may have a loose connection somewhere. That’s more likely than corrosion on something basically brand new IMO. At that point you really need to get a wiring diagram and pick through it. With newer stuff, it’s likely that you get a signal into a black box of some type like the dash, and it then kicks a signal out to the fuel pump, starter solenoid, etc, rather than a completely analog system. Trouble with that is it’s generally a ”best guess” that the dash, computer, etc is bad.
It’s unlikely to be a safety switch like the park position or brake pedal sensor if you’re not even getting dash power, but if it turns into that but no crank I’d check them.
At that point, it can be handy to have another machine to swap modules with, assuming they haven’t done something completely retarded like VIN matched them and locked them with security features. Ducati has since 2007 ish FWIW.
