Information on 2024 Hison 550x Stryker with a No start Issue

[KWinTX]

I just bought a new 2024 Hison 550 Stryker 2 months ago. this is the second time I have had this issue.  It only has about 20 hours on it. The last time it happened we took it back to the dealer. it was a fuse.  Since we live three-hour time driving there and back. I would like to find another solution if possible.  I have tried all the fuses that seem to have anything to do with starting.  Currently checking the battery. The battery is new. it came with the unit. It is probably 6 months old.  the UTV has all power to everything electrical. lights turn signals and radio all work.  When trying the key to start . it is 100% dead. as in it doesn't even click.  There is a low whirring like the fuel pump is turning on though. The Unit was running and driving just fine.  we shut it down for the night. The next morning my wife found it in this condition.  Thanks for any Ideas or solutions???   Otherwise, it goes back to the dealer tomorrow. Just hope I didn't buy a lemon. Great little UTV when it does run.😅  anyone else ever have this Issue..?

The whirring noise is the fuel pump building up pressure. It should stop about 3 to 5 seconds after turning the key to "on" position, (but not to start). 

With all other electricals all functioning, it doesn't sound like a battery issue.   No clicking, no reaction to "start" sounds like there is not 12v coming off the key switch to the starter solenoid.

From what you described, I'd be betting that the transmission neutral safety switch being defective or out of adjustment.  Thus not allowing 12v through the key switch to the starter solenoid. 

With it in neutral (so you can roll it forward and backward and everyone out of the way) jump 12v to the starter solenoid, it should kick the starter over. Don't let it start the engine, pull a plug wire for safety.

IF that works OK, then suspect the neutral or other safety switch.  If you connect a test light to the starter solenoid's 12v tab that comes from the key switch, you can start wiggling and pulling things on the shifter mechanism to see if you get a quick flash of the test lamp.  Otherwise, get in there with a voltage/continuity tester to see where your 12v is failing to reach the starter solenoid.  

My 2021 Hisun (Coleman branded) 550 has no brake safety but yours might, its a later model .  I do know that if the shifter is even slightly out of the "N" position or if the "N" light on the dash isn't on, you will get nothing when turning the key to start, but everything else electrical will work.  Sounding familiar?

Good luck, let us know how you are coming along.

Yea. that sounds a lot like what has happened.  we were getting the fault code for the gear shift. then it went away. It is a known Hisun problem. everyone says to ignore it.  we did until this happened.   I put a meter across the battery . it is fully charged. the reading just in front of the fuse block also shows full 12+ volts. I changed about every fuse with store bought replacements. It has been years since I worked on much of anything. Do not feel comfortable doing something that might void my warranty. I figured I would check the simple stuff first. get some ideas from others.  Since it is brand new with this being the second time doing it. As much as I hate it.  I think I better get it to the dealer just in case there is something more serious going on..  Thanks for the quick response. I really appreciate it.. It gives me a better idea of what might be happening since the main electrical is powering up.

You also might consider talking to the selling dealer to push for a full replacement of your unit with a new one since it is an on going issue from new and the first dealer attempt to fix didn't fix it. 

If they resist, ask for the owner of the dealership and ask him/her how they are going to make you a happy customer.  That might make your next dealer visit the last one for a while. 

Good luck on it.

Thanks,.. got it fixed, turns out there is a fuse interconnected with the brake safety interlock.  It prevents the gearshift from being recognized.  the linkage for the shifter was adjusted and that should solve all problems..  If any one has the same issue with a non start. it might be caused by the brake interlock system fuse. a 10 amp fuse popped.  I had changed most of the fuses with the Start and Run functions. never thought there would be a connection to the brakes.  weird Chinese Engineering I guess.
