I have a 2019 hi sun 750 I parked it in my garage last fall and about a month later I went to ride it and I had no power but the battery shows good. I’ve taken the ignition switch out and cleaned it. I cleaned the battery terminals and replace the main relay all my fuses are good. I still show strong battery but get no power, can anyone help or have any ideas? I have yet to find any wires chewed up like from a mouse or anything all the wiring looks good.

I’ve tried to jump across the solenoid and all it does is turn over no power to the dash any of the gauges or any of the equipment on it like the winch or hazard lights I don’t see any wires chewed up I’ve replaced the main relay and the ignition switch.

I hate to bring up an "old" thread, but did you ever get this solved?  I have exactly the same issue with my 2021 Hisun 750 ATV. I attempted to start it a week ago, it turned over, then just shut off completely after abut 5 seconds...No power to the dash, winch, lights, turn signals, etc. will not turn over or start.  Shorting the solenoid will only spin the starter motor, and not actually "start" the vehicle.  I read somewhere else about a "dash ECU Fuse" causing a similar problem - mine tests fine with my multimeter....  I need my machine to work!

I had this problem after sitting for a while cause of a blown head gasket. I fixed the head. Then tackled the no start issue. Turned out to be bad connection at battery leads. Also in the battery compartment is the main fuse. Check all connections while your in there.

 

Yes now got over 200 miles on the new head gasket and jug. 

 

Hope for the best. Let us know. We will figure this out

our XS-750 has the same problem. I can jumper the starter and it spins the motor at a very good speed but the engine and displays have no power. Battery tests show the battery is plenty strong. This beautiful pile of junk has only 19 hours on it.  We bought this for my mother in law May2024 ( sadly, she passed away last month) and she did not register it for the warranty so I am stuck with whatever problem it has. It seems to be the Keyfob module since I can try different combinations of pressing the 3 buttons on the keyfob and the displays sometime come to life and it starts and runs fine until I shut it off and then it goes dormant again. I have read several stories where the keyfob module goes bad and HISUN even has a YouTube video on how to replace it. I hope to jumper across the Keybob module bypassing it and eliminate that defect in the design once and for all.

My son in law had this problem. Turned out to be something as simple as the key fob, lol. He pressed a button or two on it and started right up. Make sure your fob is nearby with good battery. You might have to press a certain button on it. I’d tell you but I haven’t taken my fob out of the glove box in so long I don’t know what buttons are on it. Hope this helps.

even though my keyfob's red led was lighting up when I pressed the buttons, I found out how to open the case and replace the battery. That was the problem Everything is working fine now. Thanks for the advice. I am a happy man.

      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!

      Is an ATV rally a good fit for our seasonal nudist campground?
      By mehe
      Hi everyone and I hope that is not a too forward questions for us newbies. 
      My husband and I are ready (next Spring) to open our newly developed nudist campground in Iowa and we are now looking for interesting activities to host. 
      Don't worry we are not going to try and sell you a membership because as of 2 weeks ago all of our 50 campsites are sold out for the 2024 season. 
      It was my job to sell site and now that is complete i am looking for interesting actives host for weekend. 
      We have 300 acres of woods, grassland, swamps and 2 small ponds/lakes and dozens of miles of riding trails.
      we have gotten county approval for the complete 300 acres to be clothing optional. 
      We think we have a great spot for a weekend or several day ATV / mudder event. 
      Clothing would be optional for all participants and plenty of room for overnight camping and outdoor group showers. 
      Now we are looking to you pro  ATV riders to let us know if you think your group of people would fit in with ours. 
      Feel free to ask anything you would like to get a better idea of what we offer.

      Hoping someone out there somewhere can help.....2019 Massimo Buck 400S
      By AaronD1982
      Onto the next problem, everything has been replaced in the charging system except the Flywheel Rotor, I have it torn apart all the way down to said rotor, but it is suggested that a specific puller is required, and a compatible rotor seems virtually impossible to find.  I can find many like it, but this one is mine scenario for those that get the reference.  For all I know I have the last Massimo Buck 400S on the planet and will never find another part again, but who knows.  Any ideas, help or otherwise that anyone might have would be greatly appreciated.

      Some recent Hisun Sector 750 mods
      By HighSon
      Haven't posted in a while since solving the excessive cabin noise issue, so I thought I would share a few upgrades to my Sector... Realize that this is driven daily on the street, so some of the mods are to make it more streetworthy.

      Locking gas door.

      Rear view mirror.

      Modified windshield for better airflow in cabin.

      Lowered and modified headrest bar for improved rear view.  Tailgate protector.

      Folding armrests.

      Overhead utility rack.  Keeps the interior cooler and dryer, too!

      Folding rear seats.

      Dust cover and seat protector.
      If anyone wants links to the rear view mirror, seats, or arrests, let me know and I will post.  But know that everything requires some level of fabrication.  The utility rack was all custom built.  Cheers!

      2018 cub cadet 750 challenger clutch issues?
      By esmarkey
      Hi, I purchased a used Cub Cadet 750 Challenger that seemed like the belt was slipping so I put a new belt in.  It still acts like the belt is slipping but now I am thinking it is the clutch? 
      What is the best way to remedy this problem? 
      Can the clutch be rebuilt?
      Are there aftermarket clutches available?
