I was wondering if anyone has a wiring diagram for a 2007 honda rancher 420 My radiator fan quit coming on and I was trying to trace the problem, but the owners manual doesn't have a wiring diagram. I hard wired the fan and it still turns also checked the main fan fuse and it was fine.

Where is the temp sensor to make the fan go on?

Welcome to the forums. On the 420 Rancher, the ECT (engine coolant temperature) sensor is located right beside the sparkplug.

I noticed in another thread you were asking about an '05 Rancher. If it's a 350 Rancher, the sensor that turns the fan on and off won't be located beside the sparkplug. The picture below will show you where it's located. Also, it won't be called an ECT sensor on the 350 Rancher, it will be called the oil thermosensor.
