 I just picked up this project that I was told would crank, but not start.  This is what I’ve figured out so far….

I installed a new battery and get all dash lights, head lights, and brake lights on when turning the ignition on.  Fuel pump even turns on.  It does not crank with the key, but would when I jumped the starter solenoid, so I replaced it…..no change.

Figured I’d check for spark and compression while I was dorking around.  Compression is 150 psi, but there is no spark.  Replaced the spark plug… no change.

So, is my new starter solenoid bad?  Could it be the brake or gear position switches even though the brakes and neutral lights come on?  Not sure where to go from here.

Did you check for 12v at starter solenoid with key in start position?

Did you you check fuses?

As he's saying, first thing is makes sure there is 12v on positive probe with negative probe on the metal chassis or even the motor itself.

I had 12V on the one post, but nothing happened when I turned the key to start it.  It ended up being a loose connection going into the relay/fuse box.  Far right connection doesn't seat the whole way.  I have it ziptied in place for now, but would like a better solution.  With the wiring fixed, I did a valve adjustment and it fired right up, but seems to be lacking power on hills.  I just ran it around my yard real quick and definitely feels like it's lacking power on anything other than flat ground.  I guess I'll have to inspect the clutch next.

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      MSU 700 Oil Burning
      By Chile
      2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
      Any and all assistance is greatly appreciated in advance.

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.

      Hisun 700 won’t start due to Break switch
      By Some random dude
      2015 Hisun 700 Utv
      the break pedal seems to not fully throw therefore it won’t engage the switch in order to start. 
      it throws enough to stop the UTV but not enough to engage the switch. 
      I used it this morning, started fine, did some work then shut it off to talk to a neighbour and it wouldn’t start after. I can hear the injectors working but the break pedal doesn’t seem to go all the way down.

      I'm looking for an engine for my Hisun 700 SXS.
      I've found a LOT of scam sites, and need to find a legitimate business to purchase a used engine.
