Hello everyone ! I recently bought Ducati 848 Evo 2011, it has 15.750km reached yet, I bought it off with 15.350km. This link shows how I'm cleaning it: https://imgur.com/a/D2Pw9Xv For cleaning I'm using: - Shampoo - Sponge - Patch - Toothbrush - Gun hose I'm a detailer and that mean's I will do anything to my bike get cleaned and to looks perfectly clean. This link shows when my bike got refreshed and I left it to get dry for about 2 hours !: https://imgur.com/a/q3nhWrn After 2 hours I wanted to take it for a short run of 30mins since it was nice weather and suddenly I went out from house and when I reached my bike I was hearing cooling system, the fan was working and there wasn't contact since I didn't turn on the bike or anything as I left it to get dry. I don't how to describe that, it never happend to me earlier, so I started to panic and I put my hands over sideways of the bike, I was feeling the air from the fan wich was matching with what I've heard, so it's the fan for sure ! 2 hours passed away and the fan still didn't stop I checked the battery and it was on 11.2, I tried to drive the bike and after 15mins of driving when I came back home I turned off the bike and the fan has stopped properly. What is wrong here ? I was reading forums and people said it's relay.
The relay has a permanent 12V supply and is switched on by the ECU grounding it so if it sticks the fan will stay on ignition off or not. So I agree it sounds like a sticking relay. Best to replace it.
