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 MSU 500. I will start and run but requires basically full throttle to move. Does this machine have a drive belt? If so how difficult to change?

Ok, battery was original, replaced it yesterday with a new one, fully charged ant went for a spin, noticed the red battery picture on the dash screen, also after 10 min drive, the power steering was jerky, like it was cutting out. I am thinking the unit is no charging when the unit is driving, should not have a light with a fully charged battery out of the box. Any suggestions, on what to replace ??

Earlier this year my battery was weak and I had to boost my mule to start it then I decided to remove the battery to check the fluid level which was very low, I set the levels and recharged the battery a few months later it did the same thing, so I had to boost it again then checked the voltage running was getting around 16 vdc ( which is too high) and fluid level was very low again and wouldn't hold a charge. Note: The battery was maybe 1-1/2 years old. Then I replaced the battery and checked the voltage running nothing changed I was only reading battery voltage it wouldn't increase with increased engine speed. I changed the voltage regulator with an aftermarket one, same thing not charging. I checked the alternator per the service manual which states .3 ohms or less it checks at .2 ohms and not shorted to ground. With the engine running I disconnected the alternator and it had around 22 vac idling and around 60 vac revving the engine, so I figured the regulator was bad so I replaced it with another new one (aftermarket) from a different company, again not charging only reading battery voltage. I did put the original voltage regulator on nothing changed still not charging. Using the manual wiring diagram did continuity checks going to the voltage regulator everything checks out OK. Now what am I missing?
