I have a 2005 Polaris Sportsman 500 HO that needs a new Sure Power Box (Electronic Control Unit). The part number is 4011085. Dealer says they cannot get this part any longer. I have checked several places and it is out of stock. I found one place that will rebuild my part, however they cannot get the Mosfet part to repair the fan function. Is anyone aware of any work-around? The dealer is offering to install a manual switch to operate the fan.

ATV wrecker in your area? There are reputable places online that sell used parts.

What are the names of the used parts ATV businesses? I am signed up for Power Sports Nation. Unfortunately they don't have my part at this time? I have checked on two ECM on ebay, but both are not the year/part number that I need. I have to have Electronic Control Module part 4011085 for a 2005 Polaris Sportsman 500 HO. Any leads to other used parts dealers will be much appreciated.

Is the fan control the only part defective ?
Yes, fan control is the defective part. I found a rebuild place, but they cannot get the Mosfet part to rebuild the fan control on the ECM. Repair shop that has our 2005 can install a manual fan control switch. I would rather find a used 4011085 and not have a manual switch though.

Try this place. They've been great to deal with.

Thank you for trying. Snowline got back to me and they do not have part 2011085 for my 2005 ATP at this time. I have several requests out looking for the part. If those don't pan out, I will have to resort to a manual fan switch. I plan to ask for some type of gauge so I know when to switch on the fan. Not a great work around, but better than nothing. Thanks again.

So why just use a manual switch? Why not use a temperature sensor to switch a fan relay?

Mark
Polaris Dealer didn't offer to install a temperature sensor. They offered to hotwire the fan so it runs all the time, or to install a manual switch for the fan.

I watched an old YouTube video on circumventing the SurePower box 4011085 for the 2005 Polaris ATP and the old comments indicate that the part 4011085 has not been available for a couple of years. I doubt I am going to find a used one anywhere. And I doubt the Polaris Dealer is going to want to watch a YouTube video to perform this YouTube work around.

I am not capable of working on this unit myself. I am at the mercy of the Polaris Dealer.
