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.

I have an issue and I'm hoping that someone can help with a little Wisdom. I have a 2016 Massimo MSU500 UTV that blew a time chain while out riding. It has been torn down to replave the chain and Sprocket amount other things that will be renewed. The problem comes in with setting Top Dead Center on the motor. The Manuals all teel one to line up hash marks on the flywheel with a point on the side cover under what's referred to in several place as a manhole cover. Its a large headed cap/bolt that unscrews and allows you to view the edge of the flywheel. There are hash marks on the flywheel that your supposed to turn the crank until you get the proper alignment between a certain hash mark and a reference point on the Case. Problem is there is NO reference point on the case there. I also have another 2016 MSU500 and a 2014 Coleman 500. Not one of these machines have a reference mark of any kind in that location. (I have pictures if needed)
I know I can use the old pull the valve covers and rotate the crank and rely on getting the right point where Both Intake and Exhaust valves are closed at hopefully the correct point in the piston stroke. Is there any other reference point that could be used for this or is this the only thing left to use for finding TDC? Gotta Love documentation that doesn't match the equipment it's supposed to be for, any help would be greatly appreciated. Even if just to tell me that's about my only option.
Thanks to all who even take the time to read my rambling question.

I have a Hisun Strike 1000 I have been trying to get going, it has only 39 hours on it, so I can only assume it has been sitting for a long time.
The issue is it is losing spark to both coils after 20-30 seconds of running, doesn't matter if it's WOT or Idle, it will shut down. What sends signal to the coils to fire? It has a crank sensor, I was thinking a CDI box, but I have not found one of those on the machine.
The rear end was busted on it when I got it, So I ordered a new one and installed it only to run into this problem. I can only imagine the problem has happened over it sitting so long and not being driven.
I originally thought it was a fuel problem, so I checked the injectors, throttle body, o2 sensors. Discovered the heating element in one of the o2 sensors was bad, so ordered both and also replaced both injectors just to be sure, then discovered it is only losing spark.

Ok guys, my turn...
Working on my neighbors 2017 Massimo MSU-500. Initial complaint was it would start and run for about 10 minutes and the just die. He replaced the fuel pump and still had the same issue. I stopped over one day to look at it and saw that it had codes flashing on the dash; 505, 336 and 337. We decided to get a new stator/crank sensor. Took it apart installed the new stator/crank sensor and nothing. It won't even start. I checked the pins on the crank sensor plug and one was in the wrong place, so I repinned it and it still won't start. I double checked the connectors and all is good. I checked the wires from the ECU to the coil, good. It appears to have spark every once and awhile but not enough to start. I replaced the coil with a known good one and still nothing. I bought the cables and downloaded the ECU hardware and everything looks good. I pulled the timing cover back off to check the flywheel keyway, it is good. I checked the timing and timing chain, good. I checked the valve lash, good. I have to put it back together but just wanted to post in case there is something else I should check before hand. I checked the 9 pin connector and it is clean. I have battery voltage on the purple wire and pins 15 and 18 on the ECU. I pulled the air filter off and I am going to put a new plug in it just for the heck of it. What ECU inputs would prevent it from starting? Why would it now not start at all after replacing the stator/crank sensor? It has to be something simple. Any help would be appreciated.
