Hello,

I purchased my 1st used ATV last fall for ice fishing and now I have some questions that I hope somebody can help me.

My temp light is on all the time when the key is turned on but my fan never runs. I tested the fan and hooked it up to the battery and the fan works good. I tested the volts going to the fan and it is only .01V. I have unplugged the thermister wire and the temp light is still on and the fan does not run. I have done alot of reading on the forums and I need some help I think. Per the wiring diagram the one wire from the fan goes to the LR-60 part and the other wire goes to the reverse speed limited.

Any help would be great, each of those parts are expense so I don't want to have to buy all of them to do a trail and error.

Now that winter is over and the weather is getting warming I thought I better fix it. When everything is working correctly how often does the cooling fan kick in and out?

Thanks,

Charles

 

When I first turn on the key, should both the temp light and fan be on? Then once I start they both should go off, correct?

 

I have a 2002 magnum and it never does what you describe.

 

Now I am really confused, here is my situation.

With the key turned on (not running) my temp light is on and the fan is not running. My volt meter is showing 0 volts running to the fan.

If I disconnect the temp senor and short the wires, the temp light is still on and the fan does not run. But I now have 6 volts running to the fan.

If I hook the fan directly to the ATV battery the fan runs.

If I use my volt meter and read the R\W (power) wire with the positive meter wire and the black volt meter to the ATV frame I get 12 volts reading. If I hook up my fan to the R\W wire and ground it to the frame the fan does not spin. I also have an extra fan and that fan gives me the same results.

So I am confused how I can have 12 volts to the fan and the fan does not spin but if I wire it directly to the battery it spins.

Please help I am over me head now on this one.

 

Sounds like the LR60 module.

I believe the module (when working correctly) provides a ground output to operate the fan. That could explain why you are reading 6V - perhaps floating ground.

I just replaced one on my trail boss yesterday. There is a person selling them new on ebay for 50 shipped - just search 4010249 - fast shipping too.

Proper operation should be nothing on with just key on (or engine running). Fan or light will only activate depending upon the resistance being measured from the thermister in the oil cooler.
