Fan wiring

I have 1996 sportsman 500 that the p/o for some reason cut the wirsing going to the rad fan and there are no wires on the sensor. So my question is how do hook it back up, does it hook up in series with the sensor on the top of the radiator with 12v going to one side of it or does the fan always get 12v and the sensor just grounds it to turn on? It seems to get hot enough that it blows antifreeze out of the fill tank or it blows the overflow hose on the radiator fill neck off, after just 1-3 minutes of idling. Thanks in advance

Typically, the fan is hot and the sensor grounds it. Since the PO removed the wiring, I'd be real suspicious and check the fan and sensor out before re-doing the wiring. The sensor could be shorted and maybe the PO got tired of listening to the fan. Or, maybe the fan shorted and burnt the wiring out. 1 to 3 minutes of idling doesn't sound like much time before it overheats. - MarkC

Figured as much but now the weird part is when you run 12v to the pos wire on the fan it turns on without even grounding the ground wire. Also the po is a good friend of mine and he had a few of his friends try to fix it. So yea they pretty much did more harm then good on it but I'm slowly getting it straightened out.
I think it was heating up so fast because the cam was worn, all it would do was idle. The second you hit the gas it would start popping but that should be here tomorrow. Just a thought.
How should I go about checking the sensor put it in some hot water and check for continuity or is there and ohm spec on it?
