By HISUN Sector 750 EPS Failu
"Mrs. Smith" doesn't like how loud our Sector 750 is. On a HISUN forum someone said the same thing about his 750. I haven't given it much thought because I've been more focused on stuff that has broken.
So, I used my decibel meter to check ours out. 4000 RPM, Low gear, under 20 MPH . . . . 97 decibels. That's above most ordinances, even state boat noise limits.
AI Overview Ninety-seven (97) decibels is considered very loud and dangerous to hearing with prolonged exposure, roughly equivalent to a newspaper press, a loud nightclub, or a snowmobile. At this level, damage can occur after just 30 minutes, necessitating hearing protection -

Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it.
Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming.
Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light.
Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
Thanks in advance and hope this all make sense!

I recently purchased a 2019 or 2020 (no manual) Massimo 400S Buck Series UTV. It ran fine for a couple days but the low battery light was flashing while it drove. It then died in the field one day and I was able to jump the battery and get it rolling enough to get back to the barn. It started both times I turned the key for a couple days after and when driven died 10 minutes later in the driveway. Even after jumping it had no juice, but with the key out of the ignition it kept trying to start, a quick look on the Google machine and it suggested starter solenoid or ignition switch was the culprit. Fair enough, let's just order a replacement solenoid, right? No way Jose....the pin connector on the UTV is a 2-pin white plastic connector and the part received is a 4 pin. How do I swap that and make it work? Can I even? Where do I find correct parts in the future?

Pulled fuel injector to see if I could clean it or if it's stuck open. Had a slide on clip that was really tough to get off. Don't see how the clip is supposed to lock into the plastic part that the injector slides into. Any videos or pics of injector replacement?

Hey all, I was just wondering what you guys consider a necessary upgrade or spare part to have or mod onto your machine.
I'm going for a kind of shtf survival rig that's not going to be SUPER heavy and I'm looking at getting:
A spare belt (I keep seeing this mentioned everywhere I look so it must be important)
A spare tire and mount( So would I need a jack like one from an old jeep or something else?)
Tire chains for the winter
And maybe a cargo bed upgrade so things don't slide out.
Bumpers because duh.
I already installed high output lights and have a windshield, roof, back window, and winch. And I outfitted a Molle panel for the back of my passenger seat with extra supplies like food, first aid, and spare mags.
Any advise on increasing durability, longevity, and having something on hand because it's absolutely necessary would be a plus.
Thanks so much!
