Hi

I have a 2022 hisun sector eps 550. 30amp fuse is blown for eps. Checked the motor and it’s fine. Opened up the controller and found a bad diode. Dealer wanted 500$ for the controller. Just posting this in case it helps someone. I couldn’t read numbers from the old one so just took a guess and replaced it with a 100v 3amp diode. IMG_1137.thumb.jpeg.28bcd42ebf6fc05c1c5a203e85b6960f.jpegIMG_1137.thumb.jpeg.28bcd42ebf6fc05c1c5a203e85b6960f.jpegIMG_1138.thumb.jpeg.2cc4c00fa3e92c57f643e939462a3f46.jpegIMG_1139.thumb.jpeg.af69614ed2870eeeebab64e8c56edaf6.jpeg

Hey, thanks for the info. My 22 rk 750 has had no eps since about April or May, just turned dead left if you let go of the steering wheel. No help at all from hisun in Texas other than tell me to take it back to rk after the mechanic had already  told me twice he had no idea what was wrong with it. Had to have a starter replaced at another dealer closer to home and they said they would check on hisun fixing the eps.  Been about 2 months and haven't heard anything. It's a decent sxs when it works but I would advise anyone to buy another brand and save a huge headache.  Where is the diode located and does it just plug in? Thanks for the info. Sorry you're in the no eps club.

It does have a code, F0001 and the red steering trouble light is illuminated on the instrument panel. Did your steering wheel turn all the way one way or the other when you let go of the wheel? Mine turned all the way to the left. I called and tried to buy a service manual not long after I bought mine in 2022 but hisun in Texas wouldn't sell me one. Dealers and authorized repair shops only. Paid over 400 to replace the starter because it dragged all the time. Rk mechanic said they all start that way. Any help would be greatly appreciated. And thanks for the info.

      Does the transmission share the crank case oil with the engine or does it have its own oil seperate from the engine?

      How to wire winch remote on Hisun Sector E1 ?
      By hdtran
      It's not immediately obvious to me how to wire a remote control (wired or wireless) on the Sector E1.
      Has anyone here done this? Do you have pictures on how to get to the wiring?
      Thanks!

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      27” Tires 2022 800sx LE
      By Pilot1996
      When researching the Tracker, I was interested in the 800SX LE. The original sales literature indicated that the LE came with 27x9x14 and 27x11x14 tires. When I went to pick up my Tracker, it had 26” tires on it. I called Tracker before paying for the Tracker and was told they had supply issues and could not get 27” tires. I’m curious to know if anyone has taken delivery of an LE with 27” tires in stalled? I just recently installed 27” tires and am happy with the added ground clearance and beefy look the machine has taken on!
