Radiator Fan

It;s about to go into the pond! 2014 RTV 1100, radiator fan won't come on. I've checked the fuse (actually checked all of them, because I found it hard to believe the radiator fan was a 30 amp fuse). I checked the relay (again, I checked them all because I couldn't confirm which relay it was). They're all good. I replaced the temperature sending unit. When I connect the fan direct to 12 volts, it works.
Any other suggestions, other than the pond?
Thanks!
 
Take out relay and jump 12 volt from the relay plug to the wire leading to fan motor... if fan runs then check the 12 volt supply to the relay plug? If that passes swap relay with another and test again. If that fails you have a bad ground or the wire from sender to relay plug is bad
..
 
Thanks! I can't even figure out which relay it is to test it.
So, if I disconnect the temp sensor, and connect my multimeter to that wire (white), I get continuity to the chassis, and to the black wire going to the fan. But, get this, if the fan is connected, I also get continuity to the white wire, which should happen.

Thread 'Can't find cooling fan relay 2011 RTV1100C. Found diagram with no names.'

Hi, I found a box of relays just above a box of fuses, but there's no cover on my relay box so I don't know what is what. My radiator fan isn't turning on, leading to boiling water out of the radiator overflow bottle. I took the fan out and thoroughly cleaned the radiator, and I tested the fan with a battery, and it ran great.

Clearly, power isn't getting to the fan when it needs to. I'd like to test the relay if I knew which one it was, and I'd like to test the thermostat switch which looks like it's on the thermostat housing.

This thing is totaled from when it hopped out of reverse...
 
I have a box of 6 relays with one empty above the fuse box. No lid, no labels. I have a box of 6 relays with one empty below the fuse box, again no lid or labels. I removed all 10 relays, tested them and put them back. No chance they were put in the same location. The 30 amp fuse is good. Well, all the fuses are good. It's killing me! I can't find a diagram of the 2 relay boxes anywhere.
