I only get a click when I try to start

[doubleO7]

Got a 2020 Ducati Monster 797 and just yesterday it suddenly wont start, it just makes a clicking noise when I turn the key. Replaced the battery with a brand new one, checked the fuses and even did a hard start via the solenoid, but none of that worked. The only way I can get it to start is by jumping it with a car battery. After riding for an hour and shutting it off, it still just clicks when I try to restart. Anybody got any leads?

If it only starts with a car battery, your system isn't supplying enough amps, you can ceck cables, terminals, and especially the starter solenoid

What's the voltage reading on the new battery after a ride? If it drops below 12.5V, your stator or regulator/rectifier might not be charging properly, even if the battery's brand new.

I'd also suspect a significant voltage drop and deeper electrical issue, given you've ruled out the battery and fuses, and bypassed the solenoid. Closely inspect the main ground cable from the battery to the frame or engine, and then the main positive cable from the battery to the starter motor. Even slight corrosion or a loose connection can cause this. It's also worth checking the starter motor itself. Even though you're getting some action with a jump, it might be drawing too much current when trying to crank on its own.

Have you tried testing the relay under load or swapping it out? If that looks fine then the next step is to get the starter checked.

My buddy had a similar issue and it turns out that the starter motor draws more current than the stock system can deliver when it begins to wear.
