This is the correct service Manual for my machine. I uploaded it to the manuals this morning for everyone.  It is a 2016 (Manufactured  2015) Massimo MSU800.  Of coarse manufactured by HISUN, like about 40% of all UTV's.  I know, I know according to some here it's a piece of junk! But I still need to know what the 4th wire is for.  LOL  Thanks!!

      Just picked up a Hisun 500 that had shift issues (corroded fan gear) which I fixed. It also didn't seem to be running smoothly then all of a sudden it got worse. It seems to miss on both idle and when pushing the gas pedal to the floor and doesn't seem to be running at full power. I've been working with a local person who is walking me through some steps, but I'd like some input from this group as well. What I've done:
      - drained the fuel tank and replaced it with 93 octane fuel and added heet to help with any water problems.
      - replaced the fuel injector.
      - disconnected the battery (several times) to allow the module to reset.
      - set the valve clearance, both intake and exhaust, within specs ... intake was tight but exhaust seemed fine.
      - replaced the battery.
      - replaced the O2 sensor.
      Nothing has helped. Not sure what the next steps are, but would appreciate any expertise that can be offered here.

      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.

      Hi All
      Just installed a predator 670 on my Landmaster. My question is can I remove the low oil pressure wire fitting and plumb my mechanical gauge into that access point?
      Thanks in advance for your advice !!

      starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.
