Hey everyone, replaced my ecm yesterday, all is running smooth except i cant get fan to come on! Running hot, all oil and coolant levels are fine, radiator is clean, all wires look great! Any idea on a starting place?

You can jump 12 volts to the fan motor itself and see if it works. If it doesn't Spal fans have replacements.https://webstore.spalusa.com/en-us/p...rcycleatv.aspx If fan works then recheck connections.

Just run separate ground and positive wire from a battery to the fan connector.

Tried the wiring trick with no luck! Guy at polaris told me about a sensor on bottom of radiator but no luck finding that either! Any other options??

Look at your other post... easier to keep posts in one area rather than jumping around.Couldn't hook the fan up to a battery to see if it works or not or what?
