Intermittant ECU Failure?

HD8 Ignition and cooling fan fail intermittantly. Is it true that the ignition and cooling are both controlled by a single module, I have spent hours trying to solve these two issues separately. Now on the third coolant tank, the first two having split. Replaced the thermostat and the fan relay. I have caught the fan not running at times, right upto Hi Temp warning from cold engine, then run two or three runs without issue. Likewise Some runs ignition fails 10 -15 times then may go two or three months without issue.


I am now suspecting one cause for both issues



Any clues people?

2014 sportsman 850 wont start

My wheeler was overheating and did the chugging and wouldnt let you throttle like it's supposed to.....now it wont start. You can jump it.

Battery good
Attachment 116643
Ignition to relay power is good. Relay works. Power to solenoid 12 v. Little black connection is only 20 miliamps.

Is it possible the computer locked down starting for some reason????

Trailblazer 250, how stiff are shocks suppose to be?

Hi, I bought an '01 trailblazer 250 that had blown front shocks, so i bought new ones on ebay. However, with the new front shocks, the atv has no front end compression basically! I can even stand on the front of the chassis (I'm 150 pounds) and jump up and down and it will only compress about half an inch to one inch. It seems WAY too stiff to me... I've also got an 02 trail boss 325 that looks to have the same shocks, and is about the same weight, but that one is nice and plush, not too stiff at all. Are new shocks just that stiff, or is something wrong with them?

Transmission Engages Slowly or Poorly

When I have my Scrammy in D after it's been parked, why does it seem like it takes so long to engage? It shifts and says it's in D but I have to feather the throttle until it engages sometimes its 2200 rpm. Is this normal?

Like a "powerband"?

Oil alternatives

Sorry for this, I have searched so many pages of options from every model polaris makes. Then when I think I have it figured out I realize my source doesn't have the same machine, so I will only ask about the specific Polaris named lube my machines call for.

I am looking for reasonable priced alternatives since I maintain four Polaris ATV's.

DHF (drive hub fluid) - Polaris p/n 2871654
AGL (synthetic gearcase lubricant) - Polaris p/n 2878068
ADF (angle drive fluid) - Polaris p/n 2871653

THANKS!!!
