2009 Hisun 700.
Well, back to square one.
I've been doing this rebuild since Jan. 2021. MANY new parts and fixes and re-starts and working/then broke/then working/then broke... and on and on. Last week I had a good ride, about 18 miles. Ran great. Parked in the garage for 2 days and then the exact same problem as last time-- Cranks and cranks, about 6 or 8 times, and then click: nothing. I get one click and a red warning light on the dash but it's too small and doesn't say what it is. It's not the battery: it's fully charged. Had it on a charger overnight afterward and still getting one click. It's like the starter is stuck or the engine is seized. The last time it happened I took it to a guy who's rebuilt many of these and he found the starter was full of oil! Black oil. He said it was black 'cause it got cooked trying to crank. Put in a new starter and he did all kinds of adjustments and between him and the neighbor it was running great. Now it's stuck again. I'll pull the starter when I calm down....
One of the MANY new parts we threw at it was a new battery. it's got plenty of power, 350 cold cranking amps. Is it possible to have TOO heavy a battery?
But has ANYONE run into this? 🙁

Well the good news is, the starter's not full of oil this time. Bad news is, the connection point is melted inside. I'm thinking something jammed inside the crankcase and the started was trying to turn against the jam and melted.

Yup--- Did that today. It turns easily in one direction and slow-but-sure in the opposite direction: compression. But it does move so it's not seized.

I fished a piece of a ball cage out of the oil filler spout several months ago and I've always felt that there must be other metal junk down in the case. I had a guy working on it but he didn't have an indoor place to take the crankcase apart to check. He did get it all timed and valves set right and it ran good once or twice. The last ride was about 18 miles with no problems. Then it sat in the garage for 2 days and wouldn't start: just cranked and cranked. Until it locked up, I guess from the starter melting. But I didn't crank long, just 6 or 8 normal cranks and was about to give up but it locked and smoked. So ... there it sits.

Interesting, the rest of the cage bearing must be in the case. Not good! Did you drain oil from engine when you found cage in spout? If not, do so and meticulously inspect oil for foreign matter.

Did you turn motor over several revolutions by hand? Did you hear or feel any grinding or resistance? Remove spark plugs prior to test.

 

What is voltage at signal wire of starter when turning key to start position.

You may have two issues, electrical and mechanical.

Oil change--- I didn't. It went to a mechanic and he did all kinds of work on valves, etc., had the valve cover off and did some things... (I know Jack about engines so I leave it to more knowledgeable people).  He did say he didn't see anything in the oil when he drained it. I had told him about the ball cage and he didn't find any debris or metal shavings . I don't know for sure if he emptied out the oil or not. I plan to borrow a neighbor's magnet/stick today and fish it down in the oil spout and see if it brings anything up.

I will try again to turn it with the plug out and try and do several revolutions.  I'll check voltage, too.

Thanks.

      I just purchased a used 2023 Massimo warrior UTV SxS 1000mx with 600 miles on it. I didn't even get a full day of riding and the driver's side rear axle broke. I'm pretty sure it was already going bad because we would hear a noise once in a while. I'm wondering if anyone else has had problems with theirs. Also looking for places to buy accessories.

      Thanks for accepting me!
      Haven't got a side by side yet, but have been shopping.   
      Any advice welcome & I am on a limited budget, so haven't decided yet on new or used.

      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      I've had a Hisun Vector E1 for just a bit longer than is required for me to do some maintenance. While it's well-overdue, it only drives 1.5km a few times each week on a fairly decent gravel road (to the letterbox), and it has worked really well right from the get-go.
      Looking at the manual it states that I need to use SAE80 API GL-4 Hypoid Gear Oil for the Main gear Case, and SAE80 API GL-5 Hypoid Gear Oil for the Front gear Case - unfortunately i can't find either of those online here in Australia. Plenty of options that look close, but, as someone who has never driven any vehicle before, I want to use the right thing and it's a tad confusing.
      My question: Since there are no oils that are bang on SAE80 (they all seem to cover a range) would Liqui Moly Hypoid GL4 Gear Oil 80W-90  & Motorex Hypoid GL-5 Gear Oil 80W90 - be ok to use? (Or any other suggestions of what I might be able to purchase online in Australia) And would I have to drain out any existing oil from both gear cases?
      This is a whole new world for me and  being able to find exactly what is specified in the manual hasn't made this easy!

      I have a 2018 cub cadet challenger 750 I bought brand new almost 2 years ago the first month I had it the exhaust broke and burnt the spark plug wire in two that was a recall so the dealership installed the new one it had a different design and it bolted up to the bottom two plugs below the spark plug the dealership said they had to Adjust the exhaust valves I get the machine back thanking everything is good now wrong not even a week after I get it back the timing chain tensioner comes apart inside the motor I take it back to the dealership They put one on I get the machine back thanking everything is good but then just like before not even a week goes by when I was riding the Machine automatically quits going come to find out the wet clutch was burned up the primary clutch head stripped off of the splines I get that fixed and then  it overheats I take it back they bleed the air out of the coolant they bring it back to me the same day that I get it back it overheats again I take it back they temporarily fix it again just enough to let the warranty run out and now the machine has been to multiple different mechanics I have had them try to bleed the air out they have stood it up on its end I have had the water pump changed I have had the fan hooked to a switch so I could leave it on all the time but still almost 2 years later not even 200 hours on the machine and I cannot ride it The dealership will not take it back as a lemon I have tried I am at my wits end I have no clue what to try next
